Method for millet processing precision inspection (EMB)
Methylene blue, eosin Y, methanol and ethanol are analytical reagents, and the experimental water should at least meet the requirements of three-grade water in GB/T6682. A.2.1 Methylene blue in alcohol solution: dissolve 312 mg of methylene blue in a 500 mL beaker containing 250 mL of methanol, stir for about 10 minutes, and then let it stand for 20 minutes to 25 minutes to allow all insoluble particles to settle. A.2.2 Eosin methanol solution: dissolve 312 mg of eosin Y in a 500 mL beaker containing 250 mL of methanol, stir for about 10 minutes, and then let it stand for 20 minutes to 25 minutes to allow all insoluble particles to settle. A.2.3 Eosin-methylene blue methanol solution: Pour solutions A.2.1 and A.2.2 into a brown narrow-necked bottle and mix them thoroughly to form a purple dye. Store in a dark place for later use. A.3 Operation method
Take about 20g of millet rice from the average sample and count out 100 whole grains without selection. Place them in a glass dish and wash them with clean water 2 to 3 times. Then add eosin-methylene blue methanol solution (A, 2.3) to immerse the rice grains. Gently shake the glass dish. After soaking for 2 minutes, discard the solution, wash with clean water 2 to 3 times and drain. Then add ethanol and shake gently for 1 minute. Drain them all. Immediately wash with clean water 2 to 3 times. Finally, place the rice grains in clean water or use test paper to absorb the moisture. Observe the surface dyeing of rice grains. Grains with pink endosperm, green cortex and embryo, blue endosperm and pink grain surface of 2/3 or more are regarded as grains with basically clean cortex (α). Count the grains with basically clean cortex and calculate the processing accuracy. A.4 Result Expression
Processing accuracy is calculated according to formula (A.1):
Where:
Processing accuracy, %:
(\·Number of grains with basically clean cortex;
Number of grains released during dyeing test
The allowable difference between the values ​​measured in two parallel tests shall not exceed 3%. The average value shall be taken as the test result, and the test result shall be rounded to an integer.CA.1
