According to GB5492-85 "Identification of color, smell and taste of grain and oilseeds". 3.6 Determination of cotyledon discolored grains
From the average sample, after sampling, randomly select complete soybean grains (excluding broken grains and obvious insect-damaged grains), spread 200 grains in a small plate, place in an oven, bake at 105℃ for 40 minutes, and take out. Cut along the cotyledon with a knife, and count the grains whose cotyledons can be seen to be light red to brown.
Cotyledon discolored grains (%) = number of cotyledon discolored grains Total number of grains in the sample
The allowable error of the double test results shall not exceed 2% of the average value, and the average value shall be taken as the determination result, and the determination result shall be rounded. 4 Packaging, transportation and storage
