COOKING :
• Application of heat in food preparation
• Heat brings about chemical, physical and
microbiological changes.
Purpose of Cooking:
1.To make its maximum value available in palatable
form.
2. To develop and enhance flavor
3. To improve its digestibility
4. To increase palatibility by improving its color
color, texture and flavor.
5. To destroy pathogenic organisms and substances
found in raw foods
