Methods for determination of purekernel yield of unhulled oilseedsThis standard applies to the inspection of purekernel yield of commercial oilseeds (with shells). Instruments and appliances
1.1Tray balance: sensitivity 0.1g;
1.2Analysis plate;
1.3Surface blood, tweezers, etc.
2Amount of sample
Net sample (excluding impurities and kernels): 200g for peanuts, tea seeds, and tung seeds; 20g for sunflower seeds and cotton seeds. 3Shelling
Shell peanuts by hand; shell tea seeds and tung seeds after breaking the shell; shell sunflower seeds by pressing with tweezers or by hand; shell cotton seeds by scissors and tweezers. Do not lose kernels when shelling. 4 Operation method
Weigh the sample (W) according to the specified amount. After shelling, remove the kernels that have no use value, weigh the total weight of the kernels (W1), and then remove the imperfect kernels according to the regulations and weigh them (W2). 5 Result calculation
The total amount of kernels and the pure kernel rate are calculated according to formulas (1) and (2): Wi
Total amount of kernels (%)=
-×100
W1-W2-2
Pure kernel rate (%)=
Total weight of kernels, g;
W1-
Imperfect kernel weight, g;
-net sample weight, g. bzxZ.net
× 100
The allowable difference between the two test results shall not exceed 1.0%. The average is the test result. The test result is rounded to the first decimal place.
