Key Topics to Revise
1
Preliminary Food Preparations
- Preliminary preparation involves steps taken before actual cooking to clean, cut, and condition ingredients.
- These processes help in removing dirt, improving digestibility, and saving time and energy during cooking.
- Common methods include washing, peeling, cutting, grating, soaking, sieving, and mashing.
2
Methods of Cooking
- Cooking methods are classified into three main categories: Moist Heat, Dry Heat, and Combination methods.
- Moist heat methods use water or steam (e.g., boiling, steaming, poaching).
- Dry heat methods use direct heat without water (e.g., roasting, baking, frying).
3
Effect of Cooking on Nutrients
- Cooking can both destroy and enhance nutrient availability.
- Water-soluble vitamins (like Vitamin C and B-complex) are prone to leaching and heat degradation.
- Fat-soluble vitamins (A, D, E, K) are more stable but can leach into cooking oils.
4
Enhancing Nutritional Value of Foods
- Traditional processes like germination (sprouting), fermentation, and malting improve nutritional quality.
- Germination increases vitamin C, B-complex vitamins, and dietary fiber.
- Fermentation breaks down anti-nutritional factors and produces beneficial gut bacteria.
