Question

What is rancidity and Carrosion
they can be prevented?​

Answer 1

Explanation:

Corrosion: It is the process in which metals are slowly eaten up by the action of air moisture or chemicals. ... Rancidity: When the substance containing oils and fats are exposed to air they get oxidised and become rancid due to which their smell, taste and colour change. This process is known as rancidity.

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.

I hope that's helpfull so mark me brainlist.

Answer 2

When fats and oils are oxidised, they become rancid and their smell and taste change. To prevent rancidity antioxidants (which prevent oxidation) are added to foods containing fats and oils. Rancidity can also be prevented by flushing out oxygen with an inert gas like nitrogen.
