Answer 2

What is Rancidity?

• The oxidation of oils or fats in food resulting in a bad smell and bad taste is called rancidity.
• When unsaturated components of a fatty material are exposed to sunlight, they can be converted into hydroperoxides, which break down into esters, volatile aldehydes, ketones, alcohols, and hydrocarbons, some of which have unpleasant odours.

Prevention methods

Rancidity can be prevented by following ways:

• By adding anti-oxidants to foods containing fats and oils.
• Food items leftover can be refrigerated.
• Flush the food with nitrogen gas.
• Use tight containers where the air is not allowed to come in contact with the food.
