Question

What is rancidity?

Answer 1

Rancidity

1. It is a condition in which aerial oxidation of unsaturated fat present in food gives it an unpleasant flavor and odor.
2. Rancidity makes food undesirable for consumption.
3. When unsaturated fats are exposed to air it converts into hydroperoxide.
4. This further forms volatile aldehydes, esters, hydrocarbons, alcohol, etc which gives an unpleasant odor and taste.
5. Microorganism also aids this process.

Example of rancidity:

1. Food when exposed to atmospheric air for a long duration becomes rancid.
2. Butter changes its taste and smell when kept in an open atmosphere for a longer duration.
