3 Terminology
3.1 Processing precision: the degree to which the seed coat of millet is removed. 3.2 Imperfect grains: imperfect grains that still have edible value, including the following: 3.2.1 Unripe grains: grains that are not full and dull. Worm-eaten grains: grains eaten by insects.
3.2.3 Diseased grains: grains with diseased spots on the surface. 3.2.4 Moldy grains: grains with mold on the surface or deteriorated endosperm. 3.2.5 Other imperfect grains: millet, barnyard millet and broken rice exceeding the specified limit. 3.3 Impurities: undersize through the specified sieve layer and materials with no edible value, including the following: 3.3.1 Undersize: materials that pass through a 1.0mm diameter round hole sieve. 3.3.2 Minerals: sand, coal slag, bricks and tiles, metal objects, etc. 3.3.3 Other impurities: chestnuts, foreign grains, millet with no edible value and other materials. 3.4 Broken rice: broken grains that pass through a 1.2mm diameter round hole sieve and remain on a 1.0mm diameter round hole sieve (except for the impurities removed,
will not test other items).
3.5 Color, smell, taste: refers to the comprehensive color, smell and taste of a batch of millet. 4 Classification
According to the classification method of millet, it is divided into two categories:
4.1 Stalk millet: rice made from stalk millet, with a purity of 95% or more. 4.2 Glutinous millet: rice made from glutinous millet, with a purity of 95% or more. Quality indicators
Various types of millet are classified according to processing precision.
Grade indicators and other quality indicators are shown in the following table: "Imperfect

Appendix A
Method for Inspection of Millet Processing Accuracy (EMB)
(Reference)
A1 Subject content and scope of application
This appendix specifies the instruments and utensils, reagents, operation methods and result calculations used to inspect the millet processing accuracy. This appendix applies to the inspection of millet processing accuracy. A2 Instruments and appliances
A2.1 Balance: sensitivity 0.0001g.
A2.2 Beaker: 500mL.
Brown narrow-necked bottle: 500mL.
A2.4 Glass blood.
A2.5 Tweezers.
A3 Reagent preparation
A3.1 Reagents: methylene blue, eosin Y, methanol, ethanol. A3.2 Reagent preparation
A3.2.1 Methylene blue methanol solution
Dissolve 312mg of methylene blue in a 500mL beaker containing 250mL of methanol and stir for about 10min. Then let it stand for 20
~25min to allow all the insoluble particles to settle. A3.2.2 Eosin Methanol Solution
Dissolve 312 mg of Eosin Y in a 500 mL beaker containing 250 mL of methanol, stir for about 10 min, and then let stand for 20~
25 min to allow all insoluble particles to settle. A3.2.3 Eosin-Methylene Blue Methanol Solution
Pour solutions A3.2.1 and A3.2.2 into a brown narrow-necked bottle and mix them thoroughly to form a purple dye. Store in a dark place for later use.
A4 Operation method
Take about 20g of millet from the average sample, count out 100 whole rice grains without selection, put them in glass blood, wash them with clean water 2-3 times, then add eosin-methylene blue methanol solution (A3.2.3) to immerse the rice grains, gently shake the glass blood, soak for 2 minutes, discard the solution (A3.2.3), wash with clean water 2-3 times and drain; then add ethanol and shake gently for 1 minute, discard, and immediately wash with clean water 2-3 times. Finally, put the rice grains in clean water or use filter paper to absorb the water, observe the surface staining of the rice grains, the endosperm is pink, the cortex and embryo are green, and the endosperm is blue. Grains with pink grain surface of 2/3 or more are regarded as grains with rice skin basically removed. Directly calculate the processing accuracy percentage. Additional remarks:bzxZ.net
