Question

Oil and Fat containing food items are flushed with Nitrogen. Why?

Answer 1

Rancidity

1. The main objective of flushing nitrogen into food packets containing oil and fat products is to avoid rancidity, which results when the oil or fat combines with oxygen and produces an unpleasant odor and taste.
2. The term rancidity refers to a condition in which food has become undesirable, it is often used to describe the oxygen content of oils.
3. When oxygen molecules interact with the oil and food, the normal structure of the food is damaged, resulting in a change in odor and taste.
4. It can be avoided by adding antioxidants to leftover food and can be stored in the refrigerator.

Therefore, due to rancidity oil and fat molecules are flushed with Nitrogen.
