Millet in husk
This standard applies to commercial millet for purchase, sale, allocation, storage, processing and export. Classification
It is divided into two categories according to the skin color and grain quality of millet: UDC 633.17
GB 8232- 87
1.1 Stalk millet: the seed coat is mostly yellow (different shades) and white, beige, shiny, rice-like quality, and the purity is 95% or more. According to the dry grain weight of millet, it is divided into two types:
1.1.1 Large-grain stalk millet: the grain weight is 3.0g or more. 1.1.2 Small-grain stalk millet, the dry grain weight is less than 3.0g. 1.2 Glutinous millet (commonly known as sticky millet): the seed coat is mostly red (different shades), slightly shiny, the rice is glutinous, and the purity is 95% or more. According to the There are two types of dry grain weight:
1.2.1 Large grain millet: The grain weight is 3.0g or more. 1.2.2 Small grain glutinous millet: The dry grain weight is less than 3.0g. 2 Grade index
2.1 Various types of millet are graded by bulk density. Imperfect grains, impurities, and moisture are price increase or decrease items. The quality indexes are shown in the following table: Bulk density, g/L

2.2 All kinds of millet are priced based on Grade 2.
2.3 Hygiene items are based on GB2715--81 "Food Hygiene Standards", GB2761--81 "Standards for the Allowable Amount of Aflatoxin B in Foods", GB4809--84 "Standards for the Allowable Amount of Fluoride in Foods", GB4790--84 "Sanitary Standards and Inspection Methods for Dibromoethane Residues in Foods" Plant quarantine items shall be implemented in accordance with the relevant national regulations.
2.4 The maximum moisture limit and safe storage moisture standard for millet purchased shall be stipulated by the provinces, autonomous regions and municipalities directly under the Central Government. Approved by the Ministry of Commerce of the People's Republic of China on October 8, 1987 and implemented on April 1, 1988
