c.i. keep oily food in freezer

ii.add nitrogen gas to oily food

Answer 2

Explanation:

oxidation

The decomposition or degradation of fatty acids is often called rancidity and entails two main reactions: hydrolysis and oxidation. Hydrolysis, an enzymatic-type oxidation reaction, occurs with exposure to moisture in an oxygen-free environment, while oxidation occurs in the presence of oxygen and/or UV light.
