Aims & Objectives of Cooking

Aims & Objectives of Cooking Food: 1. Making food safe for consumption – Cooking sterilizes food partially. The growth of bacteria gets restricted at 40oC (104oF). Non-sporing bacteria are killed at temperatures above 60oC (140oF). For example, pasteurization – milk is made safe by holding it at 63oC (145oF) for 30 minutes or at 72oC (161oF) for 15 seconds. Boiling kills living cells. Spore-bearing bacteria take 4-5 hours of boiling to be destroyed. 2. Making food more digestible – Complex foods are split into simpler substances during cooking. The human body can absorb and utilize these more readily. 3. Increasing palatability 4. Making food look better – Heat brings about changes in colour, texture and overall appearance of the food, making it more appetizing. 5 .

Cereal starch is found in rice, wheat and maize. ( Thickening And Binding Agents ) When  cooked , corn wheat, or rice, begins to gelatinize at about 710c (160oF) but requires about 85-96oc (185-205oF) for maximum thickening. Cereal starches, whe...
