This document summarizes a study on biochemical changes in cabbage (Brassica oleracea L. var Capitata) leaves during senescence under different temperature conditions. The study found that protein, RNA, phosphorus, chlorophyll, and certain enzyme content decreased more under room temperature compared to refrigeration or deep fridge storage. However, most vitamin levels remained stable under refrigeration and deep fridge storage after 72 hours, except for vitamin C which decreased more under room temperature.
Biochemical changes in cabbage ( Brassica oleracea var Capitata) during senescence during storage at room temperature, refrigerated and deep fridge conditions.
- 1. Biochemical Changes in Cabbage (Brassica oleracea L. var Capitata) during senescence was at room temperature, refrigerated condition and deep fridge condition. Antik K. Bose Abstract The Biochemical changes in Brassica oleracia L. var Capitata leaf was studied during senescence at room temperature ( 30-35 - ). Many parameters have been evaluated like Protein, amino acid, Vitamins ( Vitamin K, A, C ,B6 Folic Acid, Thiamine, Riboflavin, Niacin, Cobalamine and Vitamin U), RNA, Phosphorus, Calcium, Sugar, Chlorophyll contents as well as marker enzymes have been assayed like Chlorophyllase, Catalase, Glutathione reductase, Glutathione peroxidase, Ascorbate peroxidase and Guaiacol Peroxidase. The protein content was decreased by 36.41% under room temperature after 96 hours but in refrigerated and deep fridge conditions the loss was 30.05 % and 24.45% respectively. The decrease in RNA content in room temperature, refrigerated and deep fridge conditions were 70.77%, 45.12% and 49.12% respectively after 96 hrs. The amino acid content was high in initial stages due to protein breakdown but it decreased sharply after 96 hrs in all conditions. The percentage of loss of Phosphorus and Chlorophyll was measured to be 67.97; 57.71, 45.19%; 20.16% and 54.80%; 39.07% under room temperature, refrigerated and deep fridge conditions after 96hrs for Phosphorus and Chlorophyll respectively. The Glutathione reductase activity was reduced by 66.67% at room - C after 72hrs. - C after 72hrs. Ascorbate peroxidase showed - C after 72hrs. G C after 72hrs. Most vitamin contents like Vitamin K, A, B6, Folic acid, Thiamine, Riboflavin, Niacin, Cobalamine and Vitamin U remained same in refrigerated and deep fridge conditions after 72hrs but Vitamin C s - C after 72hrs while at room temperature all vitamins showed decrease in content. - C respectively after 72hrs.
