Question

Define rancidity ? Write two prevent it? Write two examples?

Answer 1

Rancidity is a very general term and in its most general meaning, it refers to the spoilage of a food in such a way that it becomes undesirable (and usually unsafe) for consumption. When people say that a food has "gone bad," what they're usually talking about is rancidity.

For Example, Potato Chips when kept in air for a long time gives unpleasant smell and bad taste. Rancidity can be retarded by storing food in air-tight containers.

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.

• Replacing oxygen in the containers with another gas.
