Published under: Food Guide

Are you tired of keeping your food grains free from insects? Food storage and preservation is the biggest challenge a housewife faces. Cereals and cereal products are one of the most important food items consumed worldwide. The biggest threat to food grains and dry foods is infestations which may be in the form of live insects or insect eggs. Bacteria are surface contaminants of food grains and the main spoilage organisms in grains are moulds.

It is very important to store and preserve food grains so that they are free from micro-organisms that can impact health. Sun drying is one of the oldest methods used from time immemorial for preserving food grains. Drying removes moisture from the food stuff and prevents spoilage of food. This method has been also used for preserving certain vegetables, fruits, meats, dried fish, shrimps, tamarind, papads etc.

Besides sun drying, here are other simple ways of storing and preserving food grains so that they remain fresh and do not lose healthy nutrients present in them.
