5.3.1Color and odor shall be in accordance with GB/T5492. 5.3.2 Shape: visual inspection.
5.4 Physical and chemical inspection
5.4.1 Inspection of impurities and imperfect particles: Take samples as shown in Figure 1 and inspect them according to the method specified in GB/T5494. 5.4.2 Purity rate: Calculate the purity rate by using the value measured in 5.4.1 according to formula (1) (keep one decimal place): A(%) = m - (m+m=/2)
Where: A
-purity rate, %,
impurity mass, more,
m2---imperfect particle mass, g;

5.4.3. Inspection of hemp flakes and deformed grains: Sampling is as shown in Figure 1. Spread the sample flat on the laboratory table, separate the hemp flakes and deformed grains, collect the hemp flakes and deformed grains, weigh them separately on a balance, and calculate their percentages. Accurate to the unit. The hemp flake rate is calculated according to formula (2):
B(%) =m × 100
Where: B,———hemp flake rate, %,
m --hemp flake mass, g;
m--sample mass, g.
The deformed grain rate is calculated according to formula (3):
m×100
B2(%) =
Where: B2——deformed grain rate, %,
-deformed grain mass 8

-sample mass, g.
5.4.4 Tablet width inspection: Take 50 samples according to Figure 1 and divide them into five groups, with 10 seeds in each group. The seeds in each group are arranged horizontally, with the maximum horizontal diameter of a single seed on the same straight line. It is best if there is no gap or overlap between the seeds. Use a ruler to measure the length of each horizontal row, calculate the total length of the five groups, and find the average value. Keep one decimal place.
Tablet width is calculated according to formula (4):
Where: D~-tablet width, cm/10 horizontal rows of seeds, total length of five horizontal rows, cm.
5.4.5 Thousand-grain weight inspection: Take samples as shown in Figure 1 and then inspect according to GB/T5519. 5.4.6 Moisture inspection: Take samples as shown in Figure 1 and then inspect according to GB/T5497. 5.5 Safety and health inspection
