Grains, commonly referred to as cereals (maize, wheat, millet, rice, millets), pulses (beans, peas, cowpeas), oilseeds (soybean, sunflower, linseed) are the edible seeds of specific grasses belonging to the Poaceae family with or without outer layer while the grains like amaranth, buckwheat and quinoa are known as pseudo-cereal grains as they do not belong to the same family but nutritionally they are at par or superior to the grains.

GRAIN: A NUTRL-RICH TREASURE

Nature has designed the grains in a way that balanced diet along with fruits and vegetables and supply the required nutrients to our body. Cereals are dominant in low cost energy source carbohydrates while pulses are predominant in protein and oilseeds are cherished with lipids which are important macro-nutrients of human diets.

WHAT IS THE GRAIN PROCESSING?

Processing of agricultural commodity expressly grains is an important practice for their further use as raw or ingredient. Grains undergo various post-harvest pretreatments and processing steps to make them available for final consumption. The post-harvest processing of grains falls in different phases. In the primary processing the grains are cleaned, graded, sorted, dehusked/dehulled, milled, and converted into edible form. The secondary processing uses the primary processed grains using various steps to convert it into value added edible food products.

Grains are naturally covered with cellulosic materials known as hull or husk which are non-edible fibers for human consumption. To make the grain edible and ready for further processing, onset the grains are passed through various cleaners and graders with the aim of removing impurities and grading the grains into different quality fractions. The sound grains are dehusked for further processing through conventional or advanced mechanical methods. The grains are then dried to obtain optimum recommended moisture content and packed carefully in suitable packaging material for storage in warehouse/godowns until further use for consumption or processing. During the storage period, suitable care has to be taken to protect the grains from external or environmental factors such as rodents, mice, moisture, temperature, etc. GrainPro Cocoon is one of the advanced solutions (made of flexible UV-resistant Polyvinyl chloride) to safely store the dry grains like agricultural commodities without the need for chemicals. Also, the advanced techniques of grain storage involve the use of silo having the capacities of around or more than 100 tones.
