Test for the proportion of grains with the same color as the seed coat
GB/T 11760—2021
Randomly select 100 whole grains from green stalks, and identify the color of the green stalks with sensory organs. According to the regulations for white green stalks, black green barley and blue green stalks in Chapter 1, select the highland barley grains (number of grains R) that do not meet the color requirements of this category. A.2.2 Test for hulled barley content
Take about 50g (ml) of the green stalk sample after removing impurities. Weigh the hulled barley mixed in the detected highland barley (m2). A.3 Calculation of results
Calculation of the proportion of grains with the same color
The proportion of grains with the same color (S) is calculated according to formula (A, 1): Where:
The proportion of grains with the same color:
The number of green naked grains with different colors,
A.3.2 Calculation of the content of husk barley
The content of husk barley (Y) is calculated according to formula (A.2): Where:
1c0-\×1c0%
The content of husk barley, that is, the mass fraction of husk barley mixed in the sample; the mass of husk barley, in grams (g);
The mass of highland barley sample, in grams (g). The test results are retained to one decimal place. -rKaeerKa-
