- 1. TEXTURE ANALYZER Introduction Objective Application CT3 Analyser Operation Calibration
- 2. Texture: The feel,Appearance Consistencey of surface or Substance Different Texture of food- -Crispy -Crunchy -Chewy -Sticky
- 3. Objectives:- • Introduce: – Human sensory (subjective) texture perception – Instrumental (objective) measurements of the physical properties of products • Introduce texture analysis as the correlation between sensory perception and physical properties • Comparison with innovators
- 4. What is a Texture Analyzer? A texture analyzer is basically an upside down laboratory scale which continuously records the load (FORCE) response of a test material to the mechanical conditions imposed. Controlled mechanical conditions are input by an instrument. The response to these conditions becomes the measured variable allowing us to assess real-life physical properties. Bi-Directional Tests The instrument achieves this through either downward (compression) or upward (tension) movement. Instrument measures the response of the sample to an applied stress Graphical interpretation is usually shown as a function of load vs. time.

- 15. Tablet strength Tablet strength testing is therefore necessary for Research & Development of new formulations and for Quality Control.
- 16. Bi-layer Tablets Bi-layer tablets contain two or more Active Pharmaceutical Ingredients (API) in a single dosage form promoting patience convenience, compliance, and marketing. However, production of such tablets has faced great difficulties being prone to fracture along the material interface during compaction. The tablet failure is a result of weak bonding and adhesion between compacted layers. Results obtained from three bi- layer Tablets of same batch
- 17. CT3 Texture analyzer measures the force required to separate film coating from the tablet. Tablet Coating Four tablets taken from the same pack have been tested
- 18. Gelatine capsules -Soft and hard gelatine -Bloom test (gel strength) Data Set #1: Capsule 1 Data Set #2: Capsule 2
- 19. Gel capsules Soft gels are widely used in medicines. The active ingredient is packaged inside the capsule and the contents released at an appropriate time by rapture, dissolution, melting and diffusion. The rate at which these processes occur depends on the strength of the capsule.
- 20. Blister packaging Blister packs are widely used for unit dose packaging of tablets, capsules . They should have some degree of tamper-resistance avoiding accidental opening during transportation and by children but easily opened by weak patients and the elderly.

- 23. Operating Menu –CT3 Texture Analyzer:- The CT3 texture analyzer offers six test modes and one calibration mode. I. Normal test – single compression cycle. II. Hold time test – compress and hold. III. Cycle count test – compress sample several times. IV. Bloom test – compression test measures gelatin bloom strength. V. TPA test – two cycle texture profile analysis compression test. VI. Tension test – pulls apart a sample using tension force. VII. Static load test – monitors load while hanging calibration weights. The specific parameters required will depend upon the type of test chosen: Normal Test requires: trigger, deformation, speed Hold Time Test requires: hold time, trigger, deformation, speed Cycle Count Test requires: cycle count, trigger, deformation, speed Bloom Test requires: All parameters are fixed according to industry standard TPA Test requires: trigger, deformation, speed Tension Test requires: trigger, deformation, speed Static Load Test requires: none
- 24. The test parameters are defined as follows: Trigger : The load, in grams, measured by the CT3 to indicate that the probe is in contact with the sample. Once the trigger value is reached, the test will begin at the defined speed. Deformation : The total downward distance the probe will travel once the trigger value is reached. Speed : The speed at which the probe will travel the specified distance. Time : The number of seconds that the probe will be held at the defined distance during a Hold Time test. Count : The number of cycles (Speed and Distance) that will be applied to the sample during a Cycle Count test.
- 25. Display Conventions- The CT3 display contains four lines, but some result screens contain additional lines of information. In order to show more than four lines of information, screens are allowed to scroll using the Scroll knob. Scrollable screens are identified by the èê symbols in the upper right corner of the display. Whenever these symbols appear, the display can be scrolled up or down as indicated to show the lines above or below those presently displayed. In the following section describing test modes, all possible displays are shown. #Load shown in Newton # Load show in Grams HARDNESS1: XXXX.X g HARDNESS2: XXXX.X g COHESIVENESS: XXX.XX SPRINGINESS: XX.X mm ADHESION: XX.X mJ TEMP: XXX.X F HARDNESS1: XXXX.X N HARDNESS2: XXXX.X N COHESIVENESS: XXX.XX SPRINGINESS: XX.X mm ADHESION: XX.X mJ TEMP: XXX.X C
- 26. Running a Test A test is initiated by depressing the start button. The operator is reminded to attach a probe, then Press START again to zero the weight of the probe and begin the test. * Attach probe * press start To continue Depressing the select/scroll knob at any time during the test, or even while test results are displayed, Will show the current test parameters. At the completion of the test, the final results will be displayed until the start button or rest button is pressed. The reset button will return the instrument to the default display where the test mode may be selected. The start button will begin the same test again.
- 27. Normal Test – Performs a single compression of the sample then immediately returns to HOME starting position. The operator sets the trigger value, target deformation (travel distance into the sample) and the test speed using the Normal menu screen: TEST: NORMAL TRIGGER: XXX.X g DEFORMATION:XXX.X mm SPEED: X.XX mm /s
- 28. Hold time test – Performs a single compression of the sample. The sample remains compressed for programmed hold time before the probe returns to the starting position. The Operator sets the hold time, trigger value, target deformation and test speed using the Hold Time menu screen: TEST:HOLD TIME: XXXX S TRIGGER: XXX.X g DEFORMATION: XXX.X mm SPEED: XX.X mm/S
- 29. Tension test - –This test can be used to pull apart a sample, usually using grip fixtures to apply tension load on the sample. The operator sets the trigger value, target deformation and the test speed using the Tension menu screen: TEST: TENSION TRIGGER: XXX.X g DEFORMATION:XXX.X mm SPEED: XX.X mm/s
- 30. Cycle count test – Performs a programmed number of compression cycles upon a sample. The operator sets the number of cycles, trigger value, target deformation and test speed using the Cycle Count menu screen: TEST: CYCLE COUNT: XXXX TRIGGER: XXX.X g DEFORMATION :XXX.X mm SPEED: XX.X mm/s
- 31. Checking Calibration- The load calibration of the CT3 Texture Analyzer can be verified using the Static Load mode. Recommend Brookfield weight set appropriate for your CT3 load range: BEL Part No. Load Range •TA-CW-100C 100 gram •TA-CW-1000C 1000 gram •TA-CW-1500C 1500 gram •TA-CW-4500C 4500 gram •TA-CW-10KGC 10kg The frequency of the calibration verification should be set in accordance to your company procedures.
- 32. Start the calibration verification process using the select/scroll knob to set the test mode to Static Load and press the start button. The display will request that you attach the hanger mount to the probe shaft. The weight of the hanger mount itself will be zeroed by pressing the start button. The display will change to show static load active parameters once the auto zero process is complete. Attach the desired weight to the Hanger and record the load value from the display. Multiple weights may be attached to the Hanger to achieve a range of test points. TEST: STATIC LOAD *ATTACH HANGER MOUNT *PRESS START TO CONTINUE
