This video introduces students to the different methods of preparing food and explains how each method changes the properties of food.
Through familiar examples such as rice, idlis, potatoes, pakodis, peanuts, and salads, students explore the science behind boiling, steaming, fermentation, roasting, deep frying, shallow frying, and cutting or mixing foods.
They learn how heat, water, steam, microorganisms, and oil affect food's texture, flavour, aroma, safety, nutrient retention, and digestibility.
By connecting everyday cooking practices with simple scientific concepts, the lesson helps students understand why the same ingredients can produce foods with completely different characteristics depending on the preparation method.
