3 Terms
3.1 Pure grain rate: The percentage of the net sample weight minus one-half the weight of imperfect grains in the sample weight. 3.2 Imperfect grains: grains that are imperfect but still have edible value, including the following: 3.2.1 Unripe grains: grains that are not full, wrinkled to more than half of the grain surface, and significantly different from normal grains. 3.2.2 Diseased grains: grains with diseased spots on the grain surface and damaged cotyledons. 3.2.3 Broken grains: grains with incomplete, cross-sectioned, or broken cotyledons. 3.2.4 Budded grains: grains with buds or young roots breaking through the seed coat. 3.2.5 Deteriorated grains: grains with raw or deteriorated grain surfaces or deteriorated cotyledons. 3.3 Insect-eaten grains: grains that are eaten by insects and have damaged cotyledons. 3.4 Impurities: substances that pass through the specified sieve layer and have no use value, including the following: 3.4.1 Screened material: substances that pass through a 3.0mm diameter round hole sieve. 3.4.2 Inorganic impurities: soil, sand, gravel, bricks and tiles and other inorganic substances. 3.4.3 Organic impurities: peas with no edible value, foreign grains and other organic matter. 3.5 Odor and taste: the comprehensive color and odor of the peas. 4 Classification
According to the color of the seed coat of peas, they are divided into the following three categories: 4.1 White peas: peas with white, milky white and pink seed coats account for 95% or more. 4.2 Other pure color peas: peas with the same seed coat color account for 95% or more. 4.3 Variegated peas: peas that do not meet the above two categories.

5 Quality indicators
GB10460--89
5.1 Various types of peas are classified according to the net grain pure grain rate. The quality indicators of each grade are shown in the following table: Grade
Pure grain rate, %
Minimum index
5.2 All types of peas are priced according to the second grade. Quality
5.3 The limit of insect-damaged grains is 5.0%. The treatment method for the part exceeding the limit shall be stipulated by each province and autonomous region. 5.4 Sanitary indicators: in accordance with GB2715 and relevant regulations. 5.5 Plant quarantine: implemented in accordance with relevant national regulations. 6 Inspection methods
Pickup and sub-sampling of pea samples: in accordance with GB5491. 6.1
6.2 Classification inspection: in accordance with GB5493.
6.3 Inspection of pure grain rate and impurities: in accordance with GB5494, color, air spider
6.4 Inspection of insect-damaged grains: from the samples of grains that have not been inspected, 100 grains are selected as samples without selection, and the insect-damaged grains are first identified by appearance. If the appearance identification is not satisfactory, the grains are then shaved for inspection. The percentage of insect-damaged grains is calculated according to the following formula. Insect-damaged grains (%) = quantity × 100
W--the number of sample grains.
6.5 Determination of moisture: in accordance with GB5497, 6.6 Identification of smell and taste: in accordance with GB5492. 6.7 Determination of hygienic items: in accordance with GB5009.36. Packaging, transportation and storage
The packaging, transportation and storage of peas must meet the requirements of quality assurance, quantity assurance, transportation safety and classified storage, and strictly prevent pollution. Additional remarks:
