Answer 2

hey.....

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.

hope it help.
