Answer 2

Answer:

there are different methods :

Explanation:

• Cereals and pulses can be stored much longer than fruit and vegetables, which spoil easily. Spoilage, depends to a great extent on the moisture content of the food to be stored. The way grains are stored, thus, differs from the way fruit and vegetables are stored.

• Grains: Harvested grains are usually dried before being stored because moisture encourages the growth of microorganisms. They are then stored in metal or earthen containers, gunny bags or grain silos. The godowns where grains are stored are first fumigated to get rid of pests. Fumigation is the process of using the vapours of a chemical to get rid of pests and infections. The chemical can be sprayed using hand-operated machines.
• Cold storage: Fruit and vegetables are stored in cold storages, where the temperature is maintained between 0°C and 4°C. This discourages the growth of microorganisms. It also stops the enzymes present in the fruit and vegetables from spoiling them. However, if the temperature becomes too low, the stored fruit and vegetables can get destroyed. The other thing that has to be controlled in a cold storage is humidity. The humidity is kept pretty high because fruit and vegetables lose moisture when the humidity is low.
