Methods to prevent rancidity.
1 Adding anti oxident such as nitrogen.
2 Keeping food in air tight container.

Answer 2

Food turns rancid when the fats and oils within them get oxidized and the taste and smell of the food changes. Oxidation of fats generates highly reactive molecules in the rancid food which is responsible for the unpleasant odour and flavour. These chemical reactions also reduce the nutrition of the food. Some studies show that rancid food can have harmful health effects if consumed.

Rancidity can be prevented using the following methods:

Adding antioxidants (substances which prevent oxidation) to food.

Storing food in airtight containers to slow the process of rancidification.

Refrigerating food also helps to slow down rancidification.
