Explanation:

Preservation of food by using excessive cold is called deep freezing. It is done by placing the food in the freezer compartment of the refrigerator. The food gets frozen. At the very low temperature in the deep freezer, the growth of micro-organism that spoil the food is totally prevented. Hence, the frozen food remains unspoiled and fresh for a long time.

French fries, meat, seafood, dairy products, etc. are preserved by deep freezing.
