[0002] Corn kernel testing mainly includes the following aspects: Bulk density is the weight per unit volume, which reflects the fullness of the corn kernels. It is affected by moisture and impurities. The bulk density of corn is now used as the basis for grading. Generally speaking, the larger the bulk density, the higher the quality, which means that the corn kernels that are worm-eaten, empty-shelled, and shriveled are fewer. Moisture detection: Moisture refers to the ratio of the moisture content per unit weight of corn to the total weight, mostly calculated in units of 0.5%. The moisture content of newly harvested corn is related to the weather near maturity, the maturity of the corn, etc. Imperfect kernels refer to corn kernels that have defects such as insect damage, disease spots, sprouts, mildew, damage, frostbite, baking damage, or are not ripe, but still have edible value.
