Question

A) LIST SOME METHODS THAT DESTROY FOOD NUTRIENTS?

B ) STEAMING AND BOILING VEGETABLES ARE TWO PROCESSES OF COOKING FOOD.

HOW ARE THEY DIFFERENT?

Answer 1

A 1 If cooking is done in excess of water and the water is thrown away after cooking, many water soluble vitamins and minerals are lost.
2 If cooking is done at high temperature, many proteins and vitamins are destroyed.
3 Freezing of food materials also destroy the nutrients present in them.

B Steaming and boiling are two processes of cooking. In steaming, we use very little amount of water. So, most of the nutrients present in the vegetables are retained. While in boiling, large amount of water is used. So, when vegetables are boiled, many of their nutrients and antioxidant-carrying colours are lost in the water.
