Grain goes through a long process from planting, drying, transportation, storage to processing, etc.During this period, various chemical poisons, molds and others that are harmful to human health often contaminate the grains through various channels inadvertently, thus threatening human health. Since grains are the staple food of human beings, their hygiene and safety are particularly important.

The main problems in the course of planting, processing and marketing of grains are as follows: heavy metal pollution caused by soil and water pollution during field planting; excessive pesticide residues caused by excessive use of pesticides during field pesticide application; microbial contamination during storage and production and excessive mycotoxins, etc. Consumers who eat food with excessive microbes, heavy metals, and mycotoxins maycause damage to the body, and even die from food poisoning.

Food is the first necessity of the people. Strictly controlling the safety of grains to provide guarantee for "dishes on the menu" is needed.

According to the definition of grain in《National food safety standard-Grain》(GB 2715), grain is divided into raw grain and refined grain, including unprocessed grains, potatoes, beans and primary products processed by mechanical methods (rice, wheat flour, etc.).

In order to control the safety of grain products, a series of regulations and management measures have been issued at national and local levels, such as 《Rice》(GB/T 1354), 《Wheat flour》(GB/T 1355), 《Green food-Rice》(NY/T 419), 《Green food-Barley and barley flour》 (NY/T 891), etc.
