Can the grain depot be yellow

Rice susceptible to yellowing suffers from long-term continuous rainfall during harvest. If the rice is not threshed and dried in time, the temperature in the accumulated wet valley rises sharply, which leads to the yellowing of rice grains and the production of yellow rice, which is called yellowing valley, yellow retting valley or yellow rice. During storage, rice will turn yellow whether it is stored in warehouse or in the open air. This is closely related to the temperature and moisture of rice during storage. Rice temperature is an important factor that causes rice to turn yellow, and moisture is another factor that cannot be ignored. The interaction between rice temperature and moisture will accelerate the yellowing of rice. The higher the temperature, the greater the moisture content and the longer the storage time of rice, the more serious the yellowing will be.

After rice turns yellow, the roughness, germination rate and viscosity decrease, the acid value and unsaturated fatty acid increase, the fatty acid value and reducing sugar increase, the saturated fatty acid decreases, the broken rice increases, the regression score decreases, and the quality deteriorates obviously, which has a great influence on the edible quality and seed quality. Rice not only can't be dried in time in rainy weather at harvest, which leads to the yellowing of grain piles when heated, but also turns yellow during storage, which is mainly related to the temperature and moisture during storage.
