HOW IS LARGE SCALE STORAGE OF GRAINS, FRUITS AND VEGETABLES DONE?

Dear student.

Grains are stored in jute bags or metallic bins. Granaries and silos are used for large-scale storage of grains. This protects the grains from pests like insects and rodents.
Vegetable and fruits are stored at a low temperature of −10°C to −18°C in cold storage, where growth of microorganisms is completely inhibited.  

Regards.

Storage:

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.
