What is Food Science?
Food Science is a multi-disciplinary field involving chemistry,
biochemistry, nutrition, microbiology and engineering to give one the
scientific knowledge to solve real problems associated with the
many facets of the food system. The basis of the discipline lies in an
understanding of the chemistry of food components, such as
proteins, carbohydrates, fats and water and the reactions they
undergo during processing and storage. A complete understanding
of processing and preservation methods is required including
drying, freezing, pasteurization, canning, irradiation, extrusion, to
name just a few. The ability to carry out analysis of food
constituents is developed along with statistical quality control
methods. The microbiology and the safety aspects of food must also
be understood. Other topics covered include food additives, the
physico-chemical properties of food, flavor chemistry, product
development, food engineering and packaging. Food science
integrates this broad-based knowledge and focuses it on food.
Food Science
is still a relatively new and growing discipline, brought about mainly
as a response to the social changes taking place in North America
and other parts of the developed world. The food industry, which
originally provided only primary products for final preparation in the
home, finds itself responding to market demands for more refined,
sophisticated, and convenient products. The demand for easy to
prepare, convenience foods, poses major scientific and
technological challenges which cannot be met without highly trained
scientists capable of understanding the complex
chemistry/biochemistry of food systems and knowledge of the
methods to preserve them. This increased reliance of society on
ready-to-eat foods has led to greater responsibility for processors in
terms of quality, safety and nutrition. In order to ensure high quality
and competitive products, scientific principles and new technologies

are being applied to food manufacturing and the body of knowledge
required has become that discipline called Food Science.
What is Nutrition Explain Diff Type of Nutrition?
Nutrition
is defined as the process of taking food to carry out different
function of the body needed for the survival of the organism. The
main type of Nutrition is autotrophic and heterotrophic. When an
organism can prepare its own food such as plants, they are
known as autotrophs and such type of Nutrition is known as
autotrophic Nutrition.
Heterotrophic Nutrition is a type of nutrition in which an organism is
dependent on other organism for food. Heterotrophic Nutrition is
divided as saprophytic nutrition, parasitic nutrition and holozic
.Parasitic mode of nutrition occurs when an organism drives its
nutrition from the other living organisms. Saprophytic organism is a
type of nutrition when an organism feeds on dead plants or animals.
Holozoic nutrition is a type of nutrition in which an organism takes in
whole food.

What is the properties of food ?
A property of a system or material is any observable attribute or
characteristic of that system or material. The state of a system or
material can be defined by listing its properties. A food property is a
particular measure of the food's behavior as a matter, or its
behavior with respect to energy, or its interaction with the human
senses, or its efficacy in promoting human health and well-being
(ASHRAE, 1993; McCarthy, 1997).
The Needs of a Classification
An understanding of food properties is essential for scientists and
engineers who have to solve problems in food preservation,
packaging, processing, storage, marketing, and consumption, and
even after consumption. Proper classification and terminology
comprise an essential basis for avoiding confusion or imprecision.
Classification will assist in recording available data, setting up a
global database and developing predictive relationships. Where a
large amount of data is available, but there is no way of adequately
modeling it, then there is a need to develop general conclusions or
expectations and limitations. Classifying food properties is a difficult
task, and any attempt is likely to raise questions and controversy.
Difficult though the task may be, it is now an appropriate time to
develop a well-defined terminology and classification of food
properties (Rahman, 1998b). A good classification will facilitate
sound interdisciplinary approaches to the understanding of food
UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT

properties, and of the measurement and use of food property data,
leading to better process design and food product characterization.
Proposed Classification
Paulus (1989) proposed the classification of food properties shown
in Table 1. The characteristics given for each class may be
misleading, for example "physical properties are primarily not
relevant for food quality". In many cases, physical properties are
important in determining quality characteristics; for example, in dried
food, porosity is related to speed of rehydration, and in some cases
to texture. In the case of nutritive and sensory properties, Paulus
(1989) states these as being "primarily not relevant for process
conditions" (Table 1). This may be misleading since processing
conditions always have effects on nutritive and sensory properties.
Furthermore, it is difficult to classify food properties adequately on
the basis of a combination of how they are measured (objectively or
subjectively) and their applications. Jowitt (1974) proposed a
classification of foodstuffs and their physical properties. Rahman
(1998b) settled on the list that appears at the end of the first issue of
the International Journal of Food Properties, after several revisions
based on discussions with many academics and scientists around
the world (Table 2). The classification now proposed contains four
major classes: (i) physical and physicochemical properties, (ii)
kinetic properties, (iii) sensory properties, (iv) health properties
(Table 3).

CLASSIFICATION OF FOOD PROPERTIES
Physical and Physico-chemical properties
UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT
9
Physical and physico-chemical properties are properties
defined, measured and expressed in physical and physico-
chemical ways. However, there is no clear dividing line between
these two types of properties. Paulus (1989) classified physical
properties as: mechanical properties, thermal properties,
transport properties, and other properties (electrical and
optical). It is considered misleading to use transport as a
subclass of physical properties, since many mechanical,
thermal, and electrical properties are considered transport
properties, e.g. electrical conductivity and thermal conductivity.
Moreover, among thermal properties, specific heat is a
constitutive property, whereas thermal conductivity and
diffusivity are transport properties. The classification proposed
here is similar to the classification of physical properties in
Jowitt (1974), but firstly two new subclasses, thermodynamic
properties and mass transfer properties, replace Jowitt's
subclass of diffusional and related properties; most of the
properties included in Jowitt's subclass are in fact
thermodynamic ones. The new mass transfer properties
subclass now proposed includes both mass transfer by diffusion
and mass transfer by other mechanisms, and thus is more
general. Secondly, a new subclass of physico-chemical
constants has been added.
Kinetic properties
UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT
10
Kinetic properties are kinetic constants characterizing the rates
of changes in foods. These can be divided into two groups. The
first comprises kinetic constants characterizing the rates of
biological, biochemical, chemical, physico-chemical, and
physical changes in food. It could include respiratory constants,
rate constant, decimal reduction time, half life, Arrhenius
equation constants, temperature quotient (Qw), and z value.
The second comprises kinetic constants characterizing the rates
of growth, decline and death of micro-organisms in food. It
could include such properties as specific growth rate, the
parameters of the logistic and Gompertz equations
(mathematical models of microbial growth), generation time,
square root (Ratkowsky) equation constants, decimal reduction
time, z value. It should be noted that these properties are not
actually properties of food, but properties of micro-organisms
as moderated by the food they are in.
Sensory properties
A sensory property can be defined as the human physiological-
psychological perception of a number of physical and other
properties of food and their interactions. The physiological
apparatus (fingers, mouth, eyes, taste and aroma receptors,
ears) examines the food and reacts to the food's properties.
Signals are sent to the brain which interprets the signals and
comes to a decision about the food's sensory quality; this is the

1. When the food is directly given in the veins,
it is called ______ nutrition.
a) Parenteral
b) Enteral
c) Intravenous
d) Saline
Answer: a
Explanation: Parenteral nutrition is given to
people directly in their veins. The food is in its
most basic form, like Amino Acids instead of
protein pulses, and can be absorbed by the
body directly. It is given when the person is
unconscious, has had an operation in the GI
tract etc.
2. When food is given in the stomach or
intestines directly then it is ________
nutrition.
a) Intravenous
b) Saline
c) Enteral
d) Parenteral
Answer: c
Explanation: This type of nutrition is given to
those who have been unconscious or comatose
for a longer period of time. The food is normal
food but churned into a paste and diluted
sufficiently. This food is given directly in the
stomach with the help of tubes.
3. A person who has had a renal transplant
should regulate the intake of ______
a) carbohydrates
b) proteins
c) fats
d) vitamins
Answer: b
Explanation: Kidneys are the site of blood
purification and the waste that is flushed out is
mostly nitrogenous in nature. This nitrogenous
waste is produced due to the breakdown of
proteins and amino acids. Thus, to reduce the
pressure on kidneys, the intake of proteins is
reduced.
4. To overcome diabetes, a person can increase
the intake of ______ and reduce the intake of
___________
a) carbohydrates, proteins
b) proteins, fats
c) fats, carbohydrates
d) carbohydrates, fats
Answer: c
Explanation: Diabetes is of two kinds, one
where the body cannot produce insulin and
the second in which the cells have developed
resistance to insulin so absorption of glucose
has gone down. Thus, the amount of sugar in
blood increases. To control this, the level of fat
intake can be increased. The lesser amount of
fat is needed to satisfy hunger as compared to
carbohydrates. Also, the energy produced by
oxidation of fat is much higher. Thus, to
control diabetes, consumption of
carbohydrates is reduced and the intake of fats
is increased.
5. For a person suffering from problems like
slow neural transmission, eg dementia, they
should be given __________
a) increased sodium
b) increased potassium
c) increased calcium
d) increased magnesium
Answer: b
Explanation: The cell systems use sodium and
potassium to transmit impulses. The neural
systems also use these two ions. However, the
body uses potassium more than sodium when
it comes to transmitting impulses. Thus, when
a person is suffering from neural problems,
UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT MCQs
3
especially when the impulses are being
transmitted slowly, increasing the levels of
potassium in the body helps stabilize it.
6. A person who is suffering from high blood
pressure should cut down on _______
a) sodium
b) potassium
c) calcium
d) magnesium
Answer: a
Explanation: Sodium and potassium are used
by the body to conduct impulses but unlike
potassium, sodium is a much smaller ion. This
means it has higher electropositivity and a
higher capacity to attract negatively charged
ions. It attracts water molecules and causes
water retention, something which is very
harmful to a patient suffering from high blood
pressure. Thus, their sodium intake is reduced
so that the excess water is not held back in
blood and the pressure on the heart to
circulate the larger volume of blood reduces.
7. Long periods of parenteral nutrition is not
recommended because of ______
a) it increases the toxicity of blood
b) it puts pressure on the kidney
c) it puts pressure on the heart
d) it causes the GI track to degenerate
Answer: d
Explanation: When the functioning of an organ
system reduces, it starts degenerating. The
same happens with GI track. If parenteral
nutrition is given for a long period of time,
then even though the body will meet its
nutritional needs but the GI track will start
degenerating.
8. In cases of renal insufficiency, what should
take in place of proteins?
a) Triglycerides
b) Essential Amino Acids
c) Glucose
d) Vitamin K
Answer: b
Explanation: A protein is a long chain of
various amino acids which may or may not be
needed by the body. Since proteins are the
building blocks of the body, doing away with
proteins cannot be done however taking
proteins will harm the damaged kidney. In
such cases, essential amino acids are ingested
instead of taking in proteins. These essential
amino acids are directly absorbed by the body.
This allows the body to function normally and
the pressure on the kidney is kept at the
minimum.
9. In cases of muscle fatigue, which of the
Vitamin should be taken?
a) A
b) D
c) E
d) K
Answer: b
Explanation: Vitamin D helps the bones and
muscles in absorbing various nutrients. When
the levels of Vitamin D in the body go down,
the muscles feel fatigued as they are not able
to absorb the nutrients. The melanin pigments
of the skin in the presence of sunlight produce
Vitamin D but in case the levels go down, then
Vitamin D is orally taken or injected in the
muscles.
10. Which Vitamin in large amounts harms the
bones?
a) A
b) B
c) C
d) D
UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT MCQs
4
Answer: c
Explanation: Vitamin C is essentially Citric Acid.
It is found in citric fruits like oranges and
lemons. Necessary amounts are needed to
keep away colds and reduce the levels of
toxicity of the body. It helps keep the skin
clean and pimple free but it is still acidic in
nature. Excess consumption of Vitamin C can
cause the acid to react with the bones where
most of the minerals are and causes the bones
the bones to become weak.
11. Which of the following deals with how
food is adjudged by the consumer?
a) Food microbiology
b) Product Development
c) Sensory Analysis

14. Which sentence is untrue with respect to
the human body?
a) Unconsumed water broken → fats
b) Carbohydrates broken → Sugars
c) Proteins broken down → Amino acids
d) Fats broken down → Fatty acids and glycerol
Answer: a
Explanation: Water isn’t converted into
anything inside the body. It is just a carrier and
removes toxins from the body via sweat and
urine.
15. Which provides energy very slowly?
a) Carbohydrates
b) Fats
c) Proteins
d) Fibers
Answer: b
Explanation: Carbohydrates provide quick
energy. Proteins are for body growth. Fibers do
not provide energy as they don’t have any
calorific value. Hence, fats slowly provide
energy.
16. Which of the following is untrue?
a) A gram of carbohydrate or protein contains
4 calories
b) A gram of fat contains 9 calories
c) A gram of fat contains 5 calories
d) None of the mentioned

UNIT-II : NUTRITION AND DIETETICS
What is food groupbalanced diet, food pyramid,
macro and micro nutrition?
Food group
The food groups are part of a method of classification for the
various foods that humans consume in their everyday lives, based
on the nutritional properties of these types of foods and their
location in a hierarchy of nutrition.
Eating certain amounts and proportions of foods from the different
categories is recommended by most guides to healthy eating as one
of the most important ways to achieve a healthy lifestyle through
diet.
Different food guides vary in the number of categories used to
divide types of food, but the majority of them include the following
classifications: grain products; vegetables; fruits; dairy products;
meat and alternatives; fats, oils and sugars.
balanced diet
A healthy diet is good for your physical and mental health.
It can reduce the risk and severity of obesity, heart disease,
diabetes, hypertension, depression and cancer.
Very few foods are either all good or all bad. By having an idea of
the balance in your diet, it should be easier to enjoy food and be
healthy.
There are seven essential factors for a balanced diet: carbs, protein,
fat, fibre, vitamins, minerals and water.
UNIT-II : NUTRITION AND DIETETICS
Table 1: Essential nutrients for a healthy balanced diet
UNIT-II : NUTRITION AND DIETETICS
Table 2: Eat more, eat less…
Diet and weight
In general, if we eat fewer calories than our body needs for energy,
we will lose weight. If we eat more than we need we put on weight.
But this is not the whole story. We all have an individual balance
depending on how our body signals to itself to process food. Some
people burn more energy and in different ways, and this explains
some of the diversity in how we all look.
UNIT-II : NUTRITION AND DIETETICS
This can also change over time through life depending on whether
we are still growing and when we get older.
Some foods are processed by our bodies in ways that are more
healthy. This tends to be foods that release sugars more slowly and
that contain fibre.
Other foods including saturated fats and foods that are high in salt
or simple sugars can have a negative impact on health because of
how the body processes them.
Calories and lifestyle
The average number of calories you need each day can vary. It is
influenced by many factors including sex, age, metabolism, physical
activity, growth and pregnancy.
Body height, weight and size, genetics, hormone levels and any
illness can affect how much energy we need.
Average daily guidelines recommend around 2500 calories for men
and 2000 calories for women.
Differences within nutrients
There are healthy and less healthy dietary sources of nutrients,
especially for carbohydrates (carbs) and fats. These are explained
in below and in Table 12
Carbs: simple vs complex
Guidelines recommend that carbohydrates (“carbs”) form the basis
of most diets, making up half of total energy (calorie) intake. This
food group can be separated into complex (good) and simple (bad)
carbs.
UNIT-II : NUTRITION AND DIETETICS
Complex carbs (wholewheat flour and pasta, and brown rice)
contain larger chains of sugar molecules. These take longer to
digest than processed grains. This makes you feel full for longer,
helping to control your appetite.
Complex carbs provide energy and are key sources of fibre, B
vitamins and minerals.
Refined complex carbs (white flour, pasta and rice) are digested
more quickly by the body. This makes them a faster source of
energy. However, these types of carbs do not offer as many
additional nutrients. This is why whole-wheat and brown carbs help
improve the overall quality of your diet.
Simple carbs are the sugars. These can be natural (e.g. fructose
found in fruit) or refined (e.g. sucrose or glucose in soft drinks,
sweets and biscuits).
Another key carb-related term is the Glycaemic Index (GI). This
relates to how quickly the sugar is released into the blood stream.
Low GI foods release sugar slowly. This gives a prolonged supply of
energy to the body. Higher GI foods give shorter bursts of energy.
Many factors affect the GI of a carbohydrate including whether the
carb is simple or complex, how the food is cooked and also what it
is eaten with.
Fruit and vegetables are carbohydrate foods. They include a wide
range of vitamins and minerals as well as soluble fibre. Aiming for
five portions of fruit and vegetables a day is good for your heath.
Fruit juice is counted as one of your 5-a-day, but if you are watching
your weight it is better to eat whole fruit which takes longer to digest
and keeps you feeling full for longer.

UNIT-II : NUTRITION AND DIETETICS
Diet and cholesterol
Cholesterol is a compound that is similar to fat. It is needed by the
body to form the outside barrier of cells (membrane). It can be made
both by the body and consumed through sources in the diet.
Absorption of dietary cholesterol is complicated. Other factors such
as genetics can affect the overall level of cholesterol circulating in
the blood.
High levels of cholesterol in the blood are associated with damaging
arteries and heart disease.
Specifically, having high levels of low-density lipoprotein cholesterol
(LDL) and low levels of high-density lipoprotein cholesterol (HDL) in
the blood increase the risk of heart disease.
Changes in diet can make a difference though. Choosing foods with
more unsaturated fats compared to saturated fats can increase
levels of HDL (good cholesterol) and lower levels of LDL (bad
choleterol) Ways of cooking
The way that we cook and prepare food is important. Certain
cooking methods are also better at retaining the nutrients within
food.
Cooking techniques such as roasting and frying can be less healthy
if a large amount of fat (oil or butter) is added during the cooking.
However, you can fry and roast using small amounts of healthier
fats such as olive and rapeseed oil.
Grilling and steaming are widely considered to be healthier cooking
techniques in most cases.
The Food Pyramid
UNIT-II : NUTRITION AND DIETETICS
oil The Food Pyramid is designed to make healthy eating easier.
Healthy eating is about getting the correct amount of nutrients –
protein, fat, carbohydrates, vitamins and minerals you need to
maintain good health.
Foods that contain the same type of nutrients are grouped together
on each of the shelves of the Food Pyramid. This gives you a
choice of different foods from which to choose a healthy diet.
Following the Food Pyramid as a guide will help you get the right
balance of nutritious foods within your calorie range. Studies show
that we take in too many calories from foods and drinks high in fat,
sugar and salt, on the top shelf of the Food Pyramid. They provide
very little of the essential vitamins and minerals your body needs.
Limiting these is essential for healthy eating.
So in a nutshell, healthy eating involves:
 plenty of vegetables, salad and fruit
 a serving of wholemeal cereals and breads, potatoes, pasta
and rice at every meal - go for wholegrain varieties wherever
possible
 some milk, yoghurt and cheese
 some meat, poultry, fish, eggs, beans and nuts
 a very small amount of fats, spreads and oils
 and a very small amount or no foods and drinks high in fat,
sugar and salt
Supplements
If you eat a varied and balanced diet, then there is normally no need
to take any food supplements – you’ll get everything you need from
UNIT-II : NUTRITION AND DIETETICS
your food. The one exception to this is folic acid. All women of child-
bearing age who could become pregnant should take a supplement
of 400µg (micrograms) folic acid each day. If a woman does
become pregnant, she should continue to take the supplement
during the first twelve weeks of pregnancy.

What is Textile terminologies- fibre, yarn, weave,
fabric etc., classification of fibers, yarns and
weaves, Identification of fibres and weaves?
INTRODUCTION
Plain
Cotton plain is woven the simplest link a simple crossbreeding
the warp and the weft. Cotton plain is the most widely used
textile fabrics in the production of technical fabrics, lining fabrics,
ladies and men’s dress and suit materials. Generally, fabrics made
using plain weave said plain. Our printed cotton plain is
called Diana which is the best selling of all textile fabrics from
our fabric shop online. Next we offer cotton plain Aruna, it is very
fine fabric. Grasi is the breathable fabric. Some example of fabric
with plain weave are organza, chiffon, taffeta or biaz
Flannel
Cotton flannel is fabric in plain weave. Flannel may be brushed
to create extra softness or remain unbrushed. The brushing process
is a mechanical process where a fine metal brush rubs the fabric to
create fine fibers from the loosely spun yarns. Typically are single
sided flannel or double sided flannel. Double-napped flannel refers
to a fabric that has been brushed on both sides. Flannel is quite
lightweight, gratifying and soft to the touch. Our flannel's printed

cotton fabrics are calling Elmosa. Flannel is commonly used to
make tartan clothing, blankets, bedding sets and bed sheets.
Flannel fabrics are widely used in sleepwear of all textile fabrics.
Sateen
Cotton sateen is fabric in satin weave with a high sheen on the
face side, where a predominance of warp threads. The basic form is
a five-thread. Has the right or left direction by the direction of
binding points in its structure. It is used in weaving brocade, satin,
damask and sateen. Cotton sateen is used to sewing

luxury bedding sets, curtains and blouses, evening gown or
underwear and nightwear.
Twill
Cotton twill we recognize by the fact that i tis made by a set of
diagonal parallel lines going to the fabric surface from right to left or
in the opposite direction. I tis used on technical fabrics, lining, ladies
dress materials, men‘s suits, military and police uniforms. The most
widespread and best known use id in the production of denim from
which to sew jeans.

Flax
Traditional material of plant origin. From the plants are
processed stemp, from which is possible on textile use utilize only
about 10%. Flax is stronger than cotton, good wicks moisture and
heat. Flaxy and blended fabrics are used for summer outerwear and
summer shoes, decoration, canvas and bookbinding.
Viscose
Viscose stands on the border between artificial and natural
fibers. Viscose is composed of pure cellulose obtained by
processing cotton as a waste or wood processing. It is thus
chemically produced from natural raw materials. Fibers have
properties of cotton, including a creasy and manufactured fabrics
Unit-III : TEXTILES

are often a mixture of viscose and cotton or wool. Fabric keep
natural character and viscose reduce final price.
CLASSIFICATION OF YARNS
Almost any textile yarn can be used to produce such interlaced
fabrics as woven and knitted types. In weaving, the warp, or
lengthwise, yarns are subjected to greater stress and are usually
stronger, smoother, and more even and have tighter twist than
the weft, or crosswise, yarns. A sizing (stiffening) material such
as starch may be applied to warp yarns, increasing their strength to
withstand the stresses of fabric construction operations. Weft yarns,
subjected to little stress during weaving, may be quite fragile.
Warp and weft threads used in the same fabric may be of differing
diameter, producing such special effects as ribbing or cording in the
fabric. Special effects may also be obtained by combining warp and
weft yarns of fibre from differing origin, or with different degrees of
twist, or by introducing metallic threads into weaves composed of
other fibres.
Yarns for machine knitting are usually loosely twisted because
softness is desired in knit fabrics.
Types of yarn
Yarns can be described as single, or one-ply; ply, plied, or
folded; or as cord, including cable and hawser types.
Single yarns
Single, or one-ply, yarns are single strands composed of fibres held
together by at least a small amount of twist; or of filaments grouped
together either with or without twist; or of narrow strips of material;
or of single synthetic filaments extruded in sufficient thickness for
use alone as yarn (monofilaments). Single yarns of the spun type,
Unit-III : TEXTILES
7
composed of many short fibres, require twist to hold them together
and may be made with either S-twist or Z-twist. Single yarns are
used to make the greatest variety of fabrics.
Ply yarns
Ply, plied, or folded, yarns are composed of two or more single
yarns twisted together. Two-ply yarn, for example, is composed of
two single strands; three-ply yarn is composed of three single
strands. In making ply yarns from spun strands, the individual
strands are usually each twisted in one direction and are then
combined and twisted in the opposite direction. When both the
single strands and the final ply yarns are twisted in the same
direction, the fibre is firmer, producing harder texture and reducing
flexibility. Ply yarns provide strength for heavy industrial fabrics and
are also used for delicate-looking sheer fabrics.
Cord yarns
Cord yarns are produced by twisting ply yarns together, with
the final twist usually applied in the opposite direction of the ply
Unit-III : TEXTILES

twist. Cable cords may follow an SZS form, with S-twisted singles
made into Z-twisted plies that are then combined with an S-twist, or
may follow a ZSZ form. Hawser cord may follow an SSZ or a ZZS
pattern. Cord yarns may be used as rope or twine, may be made
into very heavy industrial fabrics, or may be composed of extremely
fine fibres that are made up into sheer dress fabrics.

yarns.Encyclopædia Britannica, Inc.
Novelty yarns
Novelty yarns include a wide variety of yarns made with
such special effects as slubs, produced by intentionally including
small lumps in the yarn structure, and synthetic yarns with varying
thickness introduced during production. Natural fibres, including
some linens, wools to be woven into tweed, and the uneven
filaments of some types of silk cloth are allowed to retain their
normal irregularities, producing the characteristic uneven surface of
the finished fabric. Synthetic fibres, which can be modified during
production, are especially adaptable for special effects such as
crimping and texturizing.
Unit-III : TEXTILES
9
Textured yarns
Texturizing processes were originally applied to synthetic
fibres to reduce such characteristics as transparency, slipperiness,
and the possibility of pilling (formation of small fibre tangles on a
fabric surface). Texturizing processes make yarns more opaque,
improve appearance and texture, and increase warmth and
absorbency. Textured yarns are synthetic continuous filaments,
modified to impart special texture and appearance. In the production
of abraded yarns, the surfaces are roughened or cut at various
intervals and given added twist, producing a hairy effect.
Unit-III : TEXTILES
10
Examples of textured yarns
Bulking creates air spaces in the yarns, imparting absorbency
and improving ventilation. Bulk is frequently introduced by crimping,
imparting waviness similar to the natural crimp of wool fibre; by
curling, producing curls or loops at various intervals; or by coiling,
imparting stretch. Such changes are usually set by heat application,
although chemical treatments are sometimes employed. In the early
1970s bulky yarns were most frequently produced by the “false
twist” method, a continuous process in which the filament yarn is
twisted and set and then untwisted and heated again to either
stabilize or destroy the twist. The “stuffing box” method is often
applied to nylon, a process in which the filament yarn is compressed
in a heated tube, imparting a zigzag crimp, then slowly withdrawn.
In the knit-de-knit process, a synthetic yarn is knitted, heat is
applied to set the loops formed by knitting, and the yarn is then
unraveled and lightly twisted, thus producing the desired texture in
the completed fabric.
Bulk may be introduced chemically by combining filaments of both
high and low shrinkage potential in the same yarn, then subjecting
the yarn to washing or steaming, causing the high shrinkage
filaments to react, producing a bulked yarn without stretch. A yarn
may be air bulked by enclosing it in a chamber where it is subjected
to a high-pressure jet of air, blowing the individual filaments into
random loops that separate, increasing the bulk of the material.
Stretch yarns
Stretch yarns are frequently continuous-filament synthetic
yarns that are very tightly twisted, heat-set, and then untwisted,
producing a spiral crimp giving a springy character. Although bulk is
imparted in the process, a very high amount of twist is required to
produce yarn that has not only bulk, but also stretch.

What isBody measurements-procedure, need,
figure types and anthropometry?
There are a variety of reasons why you may want to take your body
measurements. You could be making, tailoring, or purchasing
clothes, or you may be trying to gauge weight loss. Different
purposes will require different measurements but all are easy to
take with basic tools and maybe a helping hand. Use the following
steps when you take your measurements.
Method1
Using a Tape Measure
Use the correct type of tape measure. When taking body
measurements, you need to use the correct type of tape measure.
You will want to use a soft cloth or flexible plastic/rubber tape
measure, such as is used in sewing. Do not use a metal measuring
tape such as is used in construction.
2.Stand correctly. Stand straight, tall, and breathe normally when
taking measurements. Some measurements may be taken better
when exhaling, some when inhaling (it will depend on the purpose
of the measurement). This may be difficult to do yourself, so get a
friend to help you.
3.Measure correctly. You want to be sure that when you measure,
the tape is straight and in line with the appropriate body part. For
example, for most circumference measurements the tape will need
to be parallel to the floor while while lengths will need to be either
parallel or perpendicular (based on the line orientation of the body
part being measured).
UNIT-IV : APPAREL DESIGNING
D i w a k a r E d u c a t i o n H u b Page 3
4.Wear appropriate clothing. You can’t get a very accurate
measurement when wearing baggy or thick clothing, so try to wear
clothes which fit closely or wear nothing at all. Similarly, breast
measurements for women will be most accurate when wearing a
well-fitting, unpadded bra.
 If measuring for clothes tailoring, some measurements
will need to be taken with clothing on, such as pants
measurements and shoulder measurements.
5.Know when to measure circumference vs length. Different
measurements will need to be either circumference measurements
(the measurement around something) or length measurements (the
measurement between two straight points). Which is necessary
should be obvious but all will be indicated in the instructions below.
6.Write down your measurements. Make sure that you write down
the measurements as you take them, so that you do not forget them
and need to take them again.
Method2
1.Measure your upper arm. Measure the circumference around
the thickest part of your upper arm, usually at the bicep.
2.Measure your chest. Measure the circumference around your
chest at its widest point. For most men this will be at the armpits, for
most women this will be at the nipple line.[3]
3.Measure your waist. Measure the circumference around your
natural waist and your lower waist (two separate measurements).
The natural waist is the smallest point of your waist (unlike where
clothes’ waistlines are located these days) and is usually an inch or
two above your bellybutton.[4] Your lower waist is the widest part of
UNIT-IV : APPAREL DESIGNING
D i w a k a r E d u c a t i o n H u b Page 4
your waist, usually at the bellybutton or just below, where weight is
generally gained first.
4.Measure your hips. Measure the circumference around your hips
at the widest point. This will usually be roughly just above the crotch
line.
5.Measure your upper thigh. Measure the circumference around
your upper thigh at its widest point. This is usually ½ to 3/4’s of the
way up your thigh, from the knee.
6.Measure your calves. Measure the circumference around your
calf at its widest point, usually roughly ¾ of the way up from the
ankle.
7.Measure your weight. For weight monitoring, you may include
your body weight as a body measurement. This measurement will
need to be taken with a scale, either electronic or manual. You can
find scales for sale at many stores, or for use at gyms and doctor’s
offices.
8.Measure your height. The easiest way to measure your height is
to stand straight with no shoes on and place your back against a
wall. Using a pencil, place the pencil flat against the top of your
head with the writing end against the wall. Carefully mark your
height against the wall. Step away and measure from the mark
down to the floor using any measuring tape.
9.Calculate your body fat or BMI. You may wish to use the above
measurements to calculate your body fat or BMI if you are intending
to monitor your weight loss. Be aware that body fat calculations are
frequently inaccurate or unreliable, though BMI is a fairly accurate
way of measuring your weight (unless you are a fit athlete, in which
case better not).

What is Equipments and tools used for
manufacturing garments-advancements and
attachments used for sewing machine. Types of
machines used and their parts?
At some point, we all think of starting own business rather than
continuing our day job till the retirement. If you are one of such
thinkers, this post is for you. Let me share that there are many fields
for starting a business from scratch you can choose.
Starting a business in the garment industry can be considered as
one such good option. You can start your business in garment
manufacturing sector or start your own clothing label (brands) and
open a retail store. It not necessary that the guy who has
experience in the apparel industry can only start a business in
readymade garment manufacturing and other can’t. Anyone can
enter into garment manufacturing business. I have seen many
newcomers are from different fields like IT professionals, bankers
and HR professionals have started their business in this industry.
Product designing and pattern making
Garment pattern made prior to garment sample development.
The pattern for a style can be made manually.
For the pattern making of the sample products, you may be
interested in software. For this, you can purchase CAD (computer-
aided design). There are other components of the CAD systems –
pattern grading, Marker planning, Nesting, Pattern digitization. For
printing the marker paper, you need a plotter machine. With the help
of CAD software, you can estimate fabric requirement accurately
and improve the garment fit.

Fabric testing and fabric inspection
In garment manufacturing, fabric plays an important role in the
garment quality and product valuation as well as customer demand.
Secondly, 60-70 percentage cost incurred in fabrics in total garment
costing. That is why purchasing the right quality fabric for your
products is necessary. For the verifying the fabric quality parameter,
garment manufacturers prefer to set-up in-house fabric testing. You
may also like to purchase some basic fabric testing equipment – like
Fabric GSM testing machine,
 weighing scale,
 Meter scale,
 Fabric inspection (visual inspection machine).
 Color cabinet
 Fibre content
 Sample washing machine and Tumble drier
 Fabric handing equipment in the fabric store
Fabric spreading machines
For small-scale garment manufacturing, manual spreading is
viable. But if you want to scale up your business and improve
cutting room productivity and reduce cutting room manpower,
automatic spreading machines must be considered. See this post to
UNIT-IV : APPAREL DESIGNING
D i w a k a r E d u c a t i o n H u b Page 7
learn more about automatic fabric spreading process and auto
spreading machines.
Cutting table
You need cutting tables for fabric layering. You need a wide
and long table depending on the marker length and maximum fabric
width to be used. A number of fabric layers are spread over on the
flat table and whole plies are cut together as per marker. For check
and stripe design fabric layering where you need to match fabric
stripe and checks in the garment, a pin table is commonly used.
Cutting room machines and equipment
For the garment making fabric sheets need to cut as per
patterns. Various types of cutting machines are available for fabric
cutting. for cutting the fabric you can use a straight knife cutting
machine. For cutting few numbers of plies you can use round knife
cutting machine instead of the straight knife cutting machine. For
cutting small garment parts a band knife cutting machine is very
helpful.
Other fabric cutting machine, for the cutting room you may need
 A fusing machine,
 Ply number machine,
 Piping cutting machine (automatic rib cutting machine)
 Racks for storing cutting
 Trolley for moving cutting from bundle section to sewing lines
UNIT-IV : APPAREL DESIGNING
D i w a k a r E d u c a t i o n H u b Page 8
 Heat transfer printer – if your designs have printed labels and
logo, you can install the heat transfer printer and do the
printing job in-house.
With the technology advancement, cutting automation is preferred
by medium and large-scale garment manufacturers. Cutting room
efficiency is improved by many folds after using automatic textile
fabric cutting machine.
Sewing machines
Sewing machines are the heart of the garment manufacturing
factories. Different types of sewing machines are available for
making the garment products. You need to select the right mix of
sewing machines for your products or product groups. For the
selection of sewing machines and the number of sewing machines
need to be purchased for setting up your factory, you can take
advice from an expert. Just for your quick reference, a list of sewing
machines is shown below.
 Single Needle Lock Stitch (three different types of SNLS
machines are used depending on the operation. Normal
lockstitch machine, with under bed trimmer and equipped with
edge cutter)
 Feed off the Arm
 Single needle chain stitch machine
 Multi-needle chain stitch machine (e.g. Kansai Special)
 Overlock sewing machines
 Flatlock machines – Flatbed and cylinder bed types
UNIT-IV : APPAREL DESIGNING
D i w a k a r E d u c a t i o n H u b Page 9
 Double-needle lockstitch machine
 Button holing machine
 Button Sewing machine
 Zig-zag sewing machine
 Snap button attaching machine
For the garment sewing, there are many automatic and semi-
automatic machines are available. Some of the automatic sewing
machines are sewing operation and product specific. Like trouser
back pocket welting machine, Jeans back pocket setter and pocket
attachment in back panels. Logo embroidery machine.
Sewing room equipment (non-sewing machine)
Sewing room equipment includes – material handling systems,
sewing machine attachment and guides, WIP storing crate or bins,
and material transportation equipment. See the detailed list of non-
sewing machines and equipment Sewing is an important operation
in apparel manufacturing. It is called the heart of garments
manufacturing industry.
Before making a perfect garments, different cutting parts are joined
together and make a quality garment for the customer or buyer with
the help of various types of sewing machines, threads, needles,
tools and equipments. To get a quality products or garments sewing
section must be follow all the buyers’ specifications and
requirements.
What kind of tools, equipments and machines are essential for
sewing department in apparel industry? To get remarkable changes
on productions, every apparel professionals and apparel related
peoples should know about this topic Various types of machine,

Different types of machine, tools and equipment’s for sewing
section is must be needed to get desire products. To increase
garments production Quality inspector or supervisor always follows
up these kinds of machine, tools and equipments for sewing in the
garments industry.
Finishing machines and equipment
Finishing room activities involve garment checking, repair
defective garment, stain removing, mending, thread cutting, thread
removing, garment pressing and folding the garment. For these
processes, various types of finishing equipment are required. Like,
garment pressing equipment - Vacuum table and Steam iron for
pressing garments,
 Garment checking tables,
 Spotting gun etc.
 Thread trimmers
 For the garment finishing, various type finishing equipment is
there. Like bulk pressing, Tunnel finishing etc.
Garment packing
Garment folding is normally done manually. But garment
folding template is available in the market. In the garment packing
stage, hang tags must be attached to the garment. For tagging, you
need tag gun machine.
If you are making kids garment, one of compliance parameter, all
garments must be passed under needle detector machines. You
may need to buy a needle detector machine Types of Sewing

  • 1. UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT 2 What is Food Science? Food Science is a multi-disciplinary field involving chemistry, biochemistry, nutrition, microbiology and engineering to give one the scientific knowledge to solve real problems associated with the many facets of the food system. The basis of the discipline lies in an understanding of the chemistry of food components, such as proteins, carbohydrates, fats and water and the reactions they undergo during processing and storage. A complete understanding of processing and preservation methods is required including drying, freezing, pasteurization, canning, irradiation, extrusion, to name just a few. The ability to carry out analysis of food constituents is developed along with statistical quality control methods. The microbiology and the safety aspects of food must also be understood. Other topics covered include food additives, the physico-chemical properties of food, flavor chemistry, product development, food engineering and packaging. Food science integrates this broad-based knowledge and focuses it on food. Food Science is still a relatively new and growing discipline, brought about mainly as a response to the social changes taking place in North America and other parts of the developed world. The food industry, which originally provided only primary products for final preparation in the home, finds itself responding to market demands for more refined, sophisticated, and convenient products. The demand for easy to prepare, convenience foods, poses major scientific and technological challenges which cannot be met without highly trained scientists capable of understanding the complex chemistry/biochemistry of food systems and knowledge of the methods to preserve them. This increased reliance of society on ready-to-eat foods has led to greater responsibility for processors in terms of quality, safety and nutrition. In order to ensure high quality and competitive products, scientific principles and new technologies
  • 2. UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT 3 are being applied to food manufacturing and the body of knowledge required has become that discipline called Food Science. What is Nutrition Explain Diff Type of Nutrition? Nutrition is defined as the process of taking food to carry out different function of the body needed for the survival of the organism. The main type of Nutrition is autotrophic and heterotrophic. When an organism can prepare its own food such as plants, they are known as autotrophs and such type of Nutrition is known as autotrophic Nutrition. Heterotrophic Nutrition is a type of nutrition in which an organism is dependent on other organism for food. Heterotrophic Nutrition is divided as saprophytic nutrition, parasitic nutrition and holozic .Parasitic mode of nutrition occurs when an organism drives its nutrition from the other living organisms. Saprophytic organism is a type of nutrition when an organism feeds on dead plants or animals. Holozoic nutrition is a type of nutrition in which an organism takes in whole food.
  • 3. UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT 4 What is the properties of food ? A property of a system or material is any observable attribute or characteristic of that system or material. The state of a system or material can be defined by listing its properties. A food property is a particular measure of the food's behavior as a matter, or its behavior with respect to energy, or its interaction with the human senses, or its efficacy in promoting human health and well-being (ASHRAE, 1993; McCarthy, 1997). The Needs of a Classification An understanding of food properties is essential for scientists and engineers who have to solve problems in food preservation, packaging, processing, storage, marketing, and consumption, and even after consumption. Proper classification and terminology comprise an essential basis for avoiding confusion or imprecision. Classification will assist in recording available data, setting up a global database and developing predictive relationships. Where a large amount of data is available, but there is no way of adequately modeling it, then there is a need to develop general conclusions or expectations and limitations. Classifying food properties is a difficult task, and any attempt is likely to raise questions and controversy. Difficult though the task may be, it is now an appropriate time to develop a well-defined terminology and classification of food properties (Rahman, 1998b). A good classification will facilitate sound interdisciplinary approaches to the understanding of food
  • 4. UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT 5 properties, and of the measurement and use of food property data, leading to better process design and food product characterization. Proposed Classification Paulus (1989) proposed the classification of food properties shown in Table 1. The characteristics given for each class may be misleading, for example "physical properties are primarily not relevant for food quality". In many cases, physical properties are important in determining quality characteristics; for example, in dried food, porosity is related to speed of rehydration, and in some cases to texture. In the case of nutritive and sensory properties, Paulus (1989) states these as being "primarily not relevant for process conditions" (Table 1). This may be misleading since processing conditions always have effects on nutritive and sensory properties. Furthermore, it is difficult to classify food properties adequately on the basis of a combination of how they are measured (objectively or subjectively) and their applications. Jowitt (1974) proposed a classification of foodstuffs and their physical properties. Rahman (1998b) settled on the list that appears at the end of the first issue of the International Journal of Food Properties, after several revisions based on discussions with many academics and scientists around the world (Table 2). The classification now proposed contains four major classes: (i) physical and physicochemical properties, (ii) kinetic properties, (iii) sensory properties, (iv) health properties (Table 3).

To be determined objectively III. Important to define process condition from an engineering point of view. IV. Primarily not relevant for food quality. 2.Nutritive properties I. Defined by the food Itself. II. To be determined objectively. III. Primarily not relevant for process conditions. IV. Important for food quality. 3.Sensory Properties I. Defined by the food and by the people. II. To be determined subjectively. III. Primarily not relevant for process conditions. IV. Important for food quality. Table 2.

Excessive or unbalanced intake CLASSIFICATION OF FOOD PROPERTIES Physical and Physico-chemical properties
  • 8. UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT 9 Physical and physico-chemical properties are properties defined, measured and expressed in physical and physico- chemical ways. However, there is no clear dividing line between these two types of properties. Paulus (1989) classified physical properties as: mechanical properties, thermal properties, transport properties, and other properties (electrical and optical). It is considered misleading to use transport as a subclass of physical properties, since many mechanical, thermal, and electrical properties are considered transport properties, e.g. electrical conductivity and thermal conductivity. Moreover, among thermal properties, specific heat is a constitutive property, whereas thermal conductivity and diffusivity are transport properties. The classification proposed here is similar to the classification of physical properties in Jowitt (1974), but firstly two new subclasses, thermodynamic properties and mass transfer properties, replace Jowitt's subclass of diffusional and related properties; most of the properties included in Jowitt's subclass are in fact thermodynamic ones. The new mass transfer properties subclass now proposed includes both mass transfer by diffusion and mass transfer by other mechanisms, and thus is more general. Secondly, a new subclass of physico-chemical constants has been added. Kinetic properties
  • 9. UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT 10 Kinetic properties are kinetic constants characterizing the rates of changes in foods. These can be divided into two groups. The first comprises kinetic constants characterizing the rates of biological, biochemical, chemical, physico-chemical, and physical changes in food. It could include respiratory constants, rate constant, decimal reduction time, half life, Arrhenius equation constants, temperature quotient (Qw), and z value. The second comprises kinetic constants characterizing the rates of growth, decline and death of micro-organisms in food. It could include such properties as specific growth rate, the parameters of the logistic and Gompertz equations (mathematical models of microbial growth), generation time, square root (Ratkowsky) equation constants, decimal reduction time, z value. It should be noted that these properties are not actually properties of food, but properties of micro-organisms as moderated by the food they are in. Sensory properties A sensory property can be defined as the human physiological- psychological perception of a number of physical and other properties of food and their interactions. The physiological apparatus (fingers, mouth, eyes, taste and aroma receptors, ears) examines the food and reacts to the food's properties. Signals are sent to the brain which interprets the signals and comes to a decision about the food's sensory quality; this is the
  • 10. UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT MCQs 2 1. When the food is directly given in the veins, it is called ______ nutrition. a) Parenteral b) Enteral c) Intravenous d) Saline Answer: a Explanation: Parenteral nutrition is given to people directly in their veins. The food is in its most basic form, like Amino Acids instead of protein pulses, and can be absorbed by the body directly. It is given when the person is unconscious, has had an operation in the GI tract etc. 2. When food is given in the stomach or intestines directly then it is ________ nutrition. a) Intravenous b) Saline c) Enteral d) Parenteral Answer: c Explanation: This type of nutrition is given to those who have been unconscious or comatose for a longer period of time. The food is normal food but churned into a paste and diluted sufficiently. This food is given directly in the stomach with the help of tubes. 3. A person who has had a renal transplant should regulate the intake of ______ a) carbohydrates b) proteins c) fats d) vitamins Answer: b Explanation: Kidneys are the site of blood purification and the waste that is flushed out is mostly nitrogenous in nature. This nitrogenous waste is produced due to the breakdown of proteins and amino acids. Thus, to reduce the pressure on kidneys, the intake of proteins is reduced. 4. To overcome diabetes, a person can increase the intake of ______ and reduce the intake of ___________ a) carbohydrates, proteins b) proteins, fats c) fats, carbohydrates d) carbohydrates, fats Answer: c Explanation: Diabetes is of two kinds, one where the body cannot produce insulin and the second in which the cells have developed resistance to insulin so absorption of glucose has gone down. Thus, the amount of sugar in blood increases. To control this, the level of fat intake can be increased. The lesser amount of fat is needed to satisfy hunger as compared to carbohydrates. Also, the energy produced by oxidation of fat is much higher. Thus, to control diabetes, consumption of carbohydrates is reduced and the intake of fats is increased. 5. For a person suffering from problems like slow neural transmission, eg dementia, they should be given __________ a) increased sodium b) increased potassium c) increased calcium d) increased magnesium Answer: b Explanation: The cell systems use sodium and potassium to transmit impulses. The neural systems also use these two ions. However, the body uses potassium more than sodium when it comes to transmitting impulses. Thus, when a person is suffering from neural problems,
  • 11. UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT MCQs 3 especially when the impulses are being transmitted slowly, increasing the levels of potassium in the body helps stabilize it. 6. A person who is suffering from high blood pressure should cut down on _______ a) sodium b) potassium c) calcium d) magnesium Answer: a Explanation: Sodium and potassium are used by the body to conduct impulses but unlike potassium, sodium is a much smaller ion. This means it has higher electropositivity and a higher capacity to attract negatively charged ions. It attracts water molecules and causes water retention, something which is very harmful to a patient suffering from high blood pressure. Thus, their sodium intake is reduced so that the excess water is not held back in blood and the pressure on the heart to circulate the larger volume of blood reduces. 7. Long periods of parenteral nutrition is not recommended because of ______ a) it increases the toxicity of blood b) it puts pressure on the kidney c) it puts pressure on the heart d) it causes the GI track to degenerate Answer: d Explanation: When the functioning of an organ system reduces, it starts degenerating. The same happens with GI track. If parenteral nutrition is given for a long period of time, then even though the body will meet its nutritional needs but the GI track will start degenerating. 8. In cases of renal insufficiency, what should take in place of proteins? a) Triglycerides b) Essential Amino Acids c) Glucose d) Vitamin K Answer: b Explanation: A protein is a long chain of various amino acids which may or may not be needed by the body. Since proteins are the building blocks of the body, doing away with proteins cannot be done however taking proteins will harm the damaged kidney. In such cases, essential amino acids are ingested instead of taking in proteins. These essential amino acids are directly absorbed by the body. This allows the body to function normally and the pressure on the kidney is kept at the minimum. 9. In cases of muscle fatigue, which of the Vitamin should be taken? a) A b) D c) E d) K Answer: b Explanation: Vitamin D helps the bones and muscles in absorbing various nutrients. When the levels of Vitamin D in the body go down, the muscles feel fatigued as they are not able to absorb the nutrients. The melanin pigments of the skin in the presence of sunlight produce Vitamin D but in case the levels go down, then Vitamin D is orally taken or injected in the muscles. 10. Which Vitamin in large amounts harms the bones? a) A b) B c) C d) D
  • 12. UNIT-I : FOOD SCIENCE AND FOOD SERVICE MANAGEMENT MCQs 4 Answer: c Explanation: Vitamin C is essentially Citric Acid. It is found in citric fruits like oranges and lemons. Necessary amounts are needed to keep away colds and reduce the levels of toxicity of the body. It helps keep the skin clean and pimple free but it is still acidic in nature. Excess consumption of Vitamin C can cause the acid to react with the bones where most of the minerals are and causes the bones the bones to become weak. 11. Which of the following deals with how food is adjudged by the consumer? a) Food microbiology b) Product Development c) Sensory Analysis d) Food physics Answer: c Explanation: Sensory Analysis deals with how the food is adjudged by a consumer. 12. Industry lobbying, local to international rules, Quality and food safety etc includes which component of the food industry? a) R&D b) Financial Services c) Regulation d) Wholesale and distribution Answer: c Explanation: Food regulation ensures Industry lobbying, local to international rules, Quality and food safety. 13.

Which sentence is untrue with respect to the human body? a) Unconsumed water broken → fats b) Carbohydrates broken → Sugars c) Proteins broken down → Amino acids d) Fats broken down → Fatty acids and glycerol Answer: a Explanation: Water isn’t converted into anything inside the body. It is just a carrier and removes toxins from the body via sweat and urine. 15. Which provides energy very slowly? a) Carbohydrates b) Fats c) Proteins d) Fibers Answer: b Explanation: Carbohydrates provide quick energy. Proteins are for body growth. Fibers do not provide energy as they don’t have any calorific value. Hence, fats slowly provide energy. 16. Which of the following is untrue? a) A gram of carbohydrate or protein contains 4 calories b) A gram of fat contains 9 calories c) A gram of fat contains 5 calories d) None of the mentioned Answer: c Explanation: 4 calories make a gram of carbohydrate or protein and 9 calories make a gram of fat. 17.

  • 17. UNIT-II : NUTRITION AND DIETETICS What is food groupbalanced diet, food pyramid, macro and micro nutrition? Food group The food groups are part of a method of classification for the various foods that humans consume in their everyday lives, based on the nutritional properties of these types of foods and their location in a hierarchy of nutrition. Eating certain amounts and proportions of foods from the different categories is recommended by most guides to healthy eating as one of the most important ways to achieve a healthy lifestyle through diet. Different food guides vary in the number of categories used to divide types of food, but the majority of them include the following classifications: grain products; vegetables; fruits; dairy products; meat and alternatives; fats, oils and sugars. balanced diet A healthy diet is good for your physical and mental health. It can reduce the risk and severity of obesity, heart disease, diabetes, hypertension, depression and cancer. Very few foods are either all good or all bad. By having an idea of the balance in your diet, it should be easier to enjoy food and be healthy. There are seven essential factors for a balanced diet: carbs, protein, fat, fibre, vitamins, minerals and water.

  • 19. UNIT-II : NUTRITION AND DIETETICS Table 2: Eat more, eat less… Diet and weight In general, if we eat fewer calories than our body needs for energy, we will lose weight. If we eat more than we need we put on weight. But this is not the whole story. We all have an individual balance depending on how our body signals to itself to process food. Some people burn more energy and in different ways, and this explains some of the diversity in how we all look.
  • 20. UNIT-II : NUTRITION AND DIETETICS This can also change over time through life depending on whether we are still growing and when we get older. Some foods are processed by our bodies in ways that are more healthy. This tends to be foods that release sugars more slowly and that contain fibre. Other foods including saturated fats and foods that are high in salt or simple sugars can have a negative impact on health because of how the body processes them. Calories and lifestyle The average number of calories you need each day can vary. It is influenced by many factors including sex, age, metabolism, physical activity, growth and pregnancy. Body height, weight and size, genetics, hormone levels and any illness can affect how much energy we need. Average daily guidelines recommend around 2500 calories for men and 2000 calories for women. Differences within nutrients There are healthy and less healthy dietary sources of nutrients, especially for carbohydrates (carbs) and fats. These are explained in below and in Table 12 Carbs: simple vs complex Guidelines recommend that carbohydrates (“carbs”) form the basis of most diets, making up half of total energy (calorie) intake. This food group can be separated into complex (good) and simple (bad) carbs.
  • 21. UNIT-II : NUTRITION AND DIETETICS Complex carbs (wholewheat flour and pasta, and brown rice) contain larger chains of sugar molecules. These take longer to digest than processed grains. This makes you feel full for longer, helping to control your appetite. Complex carbs provide energy and are key sources of fibre, B vitamins and minerals. Refined complex carbs (white flour, pasta and rice) are digested more quickly by the body. This makes them a faster source of energy. However, these types of carbs do not offer as many additional nutrients. This is why whole-wheat and brown carbs help improve the overall quality of your diet. Simple carbs are the sugars. These can be natural (e.g. fructose found in fruit) or refined (e.g. sucrose or glucose in soft drinks, sweets and biscuits). Another key carb-related term is the Glycaemic Index (GI). This relates to how quickly the sugar is released into the blood stream. Low GI foods release sugar slowly. This gives a prolonged supply of energy to the body. Higher GI foods give shorter bursts of energy. Many factors affect the GI of a carbohydrate including whether the carb is simple or complex, how the food is cooked and also what it is eaten with. Fruit and vegetables are carbohydrate foods. They include a wide range of vitamins and minerals as well as soluble fibre. Aiming for five portions of fruit and vegetables a day is good for your heath. Fruit juice is counted as one of your 5-a-day, but if you are watching your weight it is better to eat whole fruit which takes longer to digest and keeps you feeling full for longer.

  • 23. UNIT-II : NUTRITION AND DIETETICS Diet and cholesterol Cholesterol is a compound that is similar to fat. It is needed by the body to form the outside barrier of cells (membrane). It can be made both by the body and consumed through sources in the diet. Absorption of dietary cholesterol is complicated. Other factors such as genetics can affect the overall level of cholesterol circulating in the blood. High levels of cholesterol in the blood are associated with damaging arteries and heart disease. Specifically, having high levels of low-density lipoprotein cholesterol (LDL) and low levels of high-density lipoprotein cholesterol (HDL) in the blood increase the risk of heart disease. Changes in diet can make a difference though. Choosing foods with more unsaturated fats compared to saturated fats can increase levels of HDL (good cholesterol) and lower levels of LDL (bad choleterol) Ways of cooking The way that we cook and prepare food is important. Certain cooking methods are also better at retaining the nutrients within food. Cooking techniques such as roasting and frying can be less healthy if a large amount of fat (oil or butter) is added during the cooking. However, you can fry and roast using small amounts of healthier fats such as olive and rapeseed oil. Grilling and steaming are widely considered to be healthier cooking techniques in most cases. The Food Pyramid
  • 24. UNIT-II : NUTRITION AND DIETETICS oil The Food Pyramid is designed to make healthy eating easier. Healthy eating is about getting the correct amount of nutrients – protein, fat, carbohydrates, vitamins and minerals you need to maintain good health. Foods that contain the same type of nutrients are grouped together on each of the shelves of the Food Pyramid. This gives you a choice of different foods from which to choose a healthy diet. Following the Food Pyramid as a guide will help you get the right balance of nutritious foods within your calorie range. Studies show that we take in too many calories from foods and drinks high in fat, sugar and salt, on the top shelf of the Food Pyramid. They provide very little of the essential vitamins and minerals your body needs. Limiting these is essential for healthy eating. So in a nutshell, healthy eating involves:  plenty of vegetables, salad and fruit  a serving of wholemeal cereals and breads, potatoes, pasta and rice at every meal - go for wholegrain varieties wherever possible  some milk, yoghurt and cheese  some meat, poultry, fish, eggs, beans and nuts  a very small amount of fats, spreads and oils  and a very small amount or no foods and drinks high in fat, sugar and salt Supplements If you eat a varied and balanced diet, then there is normally no need to take any food supplements – you’ll get everything you need from

It is thus chemically produced from natural raw materials. Fibers have properties of cotton, including a creasy and manufactured fabrics
  • 37. Unit-III : TEXTILES 6 are often a mixture of viscose and cotton or wool. Fabric keep natural character and viscose reduce final price. CLASSIFICATION OF YARNS Almost any textile yarn can be used to produce such interlaced fabrics as woven and knitted types. In weaving, the warp, or lengthwise, yarns are subjected to greater stress and are usually stronger, smoother, and more even and have tighter twist than the weft, or crosswise, yarns. A sizing (stiffening) material such as starch may be applied to warp yarns, increasing their strength to withstand the stresses of fabric construction operations. Weft yarns, subjected to little stress during weaving, may be quite fragile. Warp and weft threads used in the same fabric may be of differing diameter, producing such special effects as ribbing or cording in the fabric. Special effects may also be obtained by combining warp and weft yarns of fibre from differing origin, or with different degrees of twist, or by introducing metallic threads into weaves composed of other fibres. Yarns for machine knitting are usually loosely twisted because softness is desired in knit fabrics. Types of yarn Yarns can be described as single, or one-ply; ply, plied, or folded; or as cord, including cable and hawser types. Single yarns Single, or one-ply, yarns are single strands composed of fibres held together by at least a small amount of twist; or of filaments grouped together either with or without twist; or of narrow strips of material; or of single synthetic filaments extruded in sufficient thickness for use alone as yarn (monofilaments). Single yarns of the spun type,
  • 38. Unit-III : TEXTILES 7 composed of many short fibres, require twist to hold them together and may be made with either S-twist or Z-twist. Single yarns are used to make the greatest variety of fabrics. Ply yarns Ply, plied, or folded, yarns are composed of two or more single yarns twisted together. Two-ply yarn, for example, is composed of two single strands; three-ply yarn is composed of three single strands. In making ply yarns from spun strands, the individual strands are usually each twisted in one direction and are then combined and twisted in the opposite direction. When both the single strands and the final ply yarns are twisted in the same direction, the fibre is firmer, producing harder texture and reducing flexibility. Ply yarns provide strength for heavy industrial fabrics and are also used for delicate-looking sheer fabrics. Cord yarns Cord yarns are produced by twisting ply yarns together, with the final twist usually applied in the opposite direction of the ply

Cord yarns may be used as rope or twine, may be made into very heavy industrial fabrics, or may be composed of extremely fine fibres that are made up into sheer dress fabrics. diagram of single, ply, and cord yarnsSingle, ply, and cord yarns.Encyclopædia Britannica, Inc. Novelty yarns Novelty yarns include a wide variety of yarns made with such special effects as slubs, produced by intentionally including small lumps in the yarn structure, and synthetic yarns with varying thickness introduced during production. Natural fibres, including some linens, wools to be woven into tweed, and the uneven filaments of some types of silk cloth are allowed to retain their normal irregularities, producing the characteristic uneven surface of the finished fabric. Synthetic fibres, which can be modified during production, are especially adaptable for special effects such as crimping and texturizing.
  • 40. Unit-III : TEXTILES 9 Textured yarns Texturizing processes were originally applied to synthetic fibres to reduce such characteristics as transparency, slipperiness, and the possibility of pilling (formation of small fibre tangles on a fabric surface). Texturizing processes make yarns more opaque, improve appearance and texture, and increase warmth and absorbency. Textured yarns are synthetic continuous filaments, modified to impart special texture and appearance. In the production of abraded yarns, the surfaces are roughened or cut at various intervals and given added twist, producing a hairy effect.
  • 41. Unit-III : TEXTILES 10 Examples of textured yarns Bulking creates air spaces in the yarns, imparting absorbency and improving ventilation. Bulk is frequently introduced by crimping, imparting waviness similar to the natural crimp of wool fibre; by curling, producing curls or loops at various intervals; or by coiling, imparting stretch. Such changes are usually set by heat application, although chemical treatments are sometimes employed. In the early 1970s bulky yarns were most frequently produced by the “false twist” method, a continuous process in which the filament yarn is twisted and set and then untwisted and heated again to either stabilize or destroy the twist. The “stuffing box” method is often applied to nylon, a process in which the filament yarn is compressed in a heated tube, imparting a zigzag crimp, then slowly withdrawn. In the knit-de-knit process, a synthetic yarn is knitted, heat is applied to set the loops formed by knitting, and the yarn is then unraveled and lightly twisted, thus producing the desired texture in the completed fabric. Bulk may be introduced chemically by combining filaments of both high and low shrinkage potential in the same yarn, then subjecting the yarn to washing or steaming, causing the high shrinkage filaments to react, producing a bulked yarn without stretch. A yarn may be air bulked by enclosing it in a chamber where it is subjected to a high-pressure jet of air, blowing the individual filaments into random loops that separate, increasing the bulk of the material. Stretch yarns Stretch yarns are frequently continuous-filament synthetic yarns that are very tightly twisted, heat-set, and then untwisted, producing a spiral crimp giving a springy character. Although bulk is imparted in the process, a very high amount of twist is required to produce yarn that has not only bulk, but also stretch.

  • 49. UNIT-IV : APPAREL DESIGNING D i w a k a r E d u c a t i o n H u b Page 2 What isBody measurements-procedure, need, figure types and anthropometry? There are a variety of reasons why you may want to take your body measurements. You could be making, tailoring, or purchasing clothes, or you may be trying to gauge weight loss. Different purposes will require different measurements but all are easy to take with basic tools and maybe a helping hand. Use the following steps when you take your measurements. Method1 Using a Tape Measure Use the correct type of tape measure. When taking body measurements, you need to use the correct type of tape measure. You will want to use a soft cloth or flexible plastic/rubber tape measure, such as is used in sewing. Do not use a metal measuring tape such as is used in construction. 2.Stand correctly. Stand straight, tall, and breathe normally when taking measurements. Some measurements may be taken better when exhaling, some when inhaling (it will depend on the purpose of the measurement). This may be difficult to do yourself, so get a friend to help you. 3.Measure correctly. You want to be sure that when you measure, the tape is straight and in line with the appropriate body part. For example, for most circumference measurements the tape will need to be parallel to the floor while while lengths will need to be either parallel or perpendicular (based on the line orientation of the body part being measured).
  • 50. UNIT-IV : APPAREL DESIGNING D i w a k a r E d u c a t i o n H u b Page 3 4.Wear appropriate clothing. You can’t get a very accurate measurement when wearing baggy or thick clothing, so try to wear clothes which fit closely or wear nothing at all. Similarly, breast measurements for women will be most accurate when wearing a well-fitting, unpadded bra.  If measuring for clothes tailoring, some measurements will need to be taken with clothing on, such as pants measurements and shoulder measurements. 5.Know when to measure circumference vs length. Different measurements will need to be either circumference measurements (the measurement around something) or length measurements (the measurement between two straight points). Which is necessary should be obvious but all will be indicated in the instructions below. 6.Write down your measurements. Make sure that you write down the measurements as you take them, so that you do not forget them and need to take them again. Method2 1.Measure your upper arm. Measure the circumference around the thickest part of your upper arm, usually at the bicep. 2.Measure your chest. Measure the circumference around your chest at its widest point. For most men this will be at the armpits, for most women this will be at the nipple line.[3] 3.Measure your waist. Measure the circumference around your natural waist and your lower waist (two separate measurements). The natural waist is the smallest point of your waist (unlike where clothes’ waistlines are located these days) and is usually an inch or two above your bellybutton.[4] Your lower waist is the widest part of
  • 51. UNIT-IV : APPAREL DESIGNING D i w a k a r E d u c a t i o n H u b Page 4 your waist, usually at the bellybutton or just below, where weight is generally gained first. 4.Measure your hips. Measure the circumference around your hips at the widest point. This will usually be roughly just above the crotch line. 5.Measure your upper thigh. Measure the circumference around your upper thigh at its widest point. This is usually ½ to 3/4’s of the way up your thigh, from the knee. 6.Measure your calves. Measure the circumference around your calf at its widest point, usually roughly ¾ of the way up from the ankle. 7.Measure your weight. For weight monitoring, you may include your body weight as a body measurement. This measurement will need to be taken with a scale, either electronic or manual. You can find scales for sale at many stores, or for use at gyms and doctor’s offices. 8.Measure your height. The easiest way to measure your height is to stand straight with no shoes on and place your back against a wall. Using a pencil, place the pencil flat against the top of your head with the writing end against the wall. Carefully mark your height against the wall. Step away and measure from the mark down to the floor using any measuring tape. 9.Calculate your body fat or BMI. You may wish to use the above measurements to calculate your body fat or BMI if you are intending to monitor your weight loss. Be aware that body fat calculations are frequently inaccurate or unreliable, though BMI is a fairly accurate way of measuring your weight (unless you are a fit athlete, in which case better not).

Types of machines used and their parts? At some point, we all think of starting own business rather than continuing our day job till the retirement. If you are one of such thinkers, this post is for you. Let me share that there are many fields for starting a business from scratch you can choose. Starting a business in the garment industry can be considered as one such good option. You can start your business in garment manufacturing sector or start your own clothing label (brands) and open a retail store. It not necessary that the guy who has experience in the apparel industry can only start a business in readymade garment manufacturing and other can’t. Anyone can enter into garment manufacturing business. I have seen many newcomers are from different fields like IT professionals, bankers and HR professionals have started their business in this industry. Product designing and pattern making Garment pattern made prior to garment sample development. The pattern for a style can be made manually. For the pattern making of the sample products, you may be interested in software. For this, you can purchase CAD (computer- aided design). There are other components of the CAD systems – pattern grading, Marker planning, Nesting, Pattern digitization. For printing the marker paper, you need a plotter machine. With the help of CAD software, you can estimate fabric requirement accurately and improve the garment fit.
