Question

Write three methods for preventing rancidity of food.​

Answer 1

Explanation:

In order to prevent rancidity due to 1.oxygen or water vapours present in a container, vacuum packing should be used or the packing should be filled with inert gases. For Example: Potato Chips are usually packed in thick foil packets filled with Nitrogen.

2. Refrigeration of foods also reduces the rate of most of the reactions that cause rancidity.

3. Reducing the water content in foods by drying or smoking and then storing them in a moisture free environment helps to reduce the chances of rancidity.

Answer 2

1. Adding antioxidants (substances which prevent oxidation) to food.
2. Storing food in airtight containers to slow the process of rancidification.
3. Refrigerating food also helps to slow down rancidification.
4. Replacing oxygen in the containers with another gas.
