Question

Name two food materials which are usually preserved by deep freezing.

Answer 1

Preservation of food by deep freezing means the preservation of food by excessive cold. Deep freezing of food can be done by placing it in the freezer compartment of our refrigerator. When the food is kept in the deep freezer then food gets frozen.
At the very low temperature in the deep freezer, the growth of food-spoiled micro-organism is prevented completely. Due to this, the frozen food remains unspoiled and fresh for long periods. The deep freezing method is used for the preservation of food like meat, fish, fruits and vegetables.
