Why is washing food important before cooking?
Answer
Washing removes dirt, pesticides, and harmful microorganisms from the surface of fruits, vegetables, and grains. This prevents contamination and keeps food safe for consumption.
What is the purpose of peeling in food preparation?
Answer
Peeling removes the outer skin of fruits and vegetables that may be tough, inedible, or contaminated with dirt and chemicals. It improves texture and safety of the food.
Differentiate between slicing and dicing.
Answer
Slicing means cutting food into thin, flat pieces. Dicing means cutting food into small, uniform cubes. Dicing ensures even cooking in dishes like curries and stir-fries.
What is grating? Give one example.
Answer
Grating is reducing food into small particles by rubbing it on a rough surface. Example: Grating carrots for carrot halwa or cheese for pizza topping.
Why is soaking pulses before cooking beneficial?
Answer
Soaking softens pulses, reduces cooking time, and improves digestibility. It also helps remove anti-nutritional factors like phytic acid, which can interfere with mineral absorption.
What happens during sprouting (germination) of pulses?
Answer
Sprouting involves soaking pulses, then keeping them moist for 2–3 days until small sprouts appear. This process increases protein quality, B-complex vitamins, vitamin C, and digestibility.
How does fermentation improve food?
Answer
Fermentation uses microorganisms to break down sugars into lactic acid or alcohol. It improves digestibility, adds flavor, increases nutrient availability, and supports gut health with probiotics.
