The seed set by rice is rice, which is called brown rice after the husk is removed, and the rice can be obtained by grinding the brown rice to remove the rice bran layer. Rice, also known as rice, is a food made from rice after cleaning, husking, milling and finishing. Rice is the main food for people in most areas of China. Rice is one of the important food crops for human beings, and it has a long history of cultivation and consumption.
Wheat is the general name of the genus Triticum, and its representative species is common wheat or Gramineae, which is a cereal crop widely planted all over the world. The caryopsis of wheat is one of the staple foods of human beings. After being ground into flour, it can be made into bread, steamed bread, biscuits, noodles and other foods, and after being fermented, it can be made into beer, alcohol, white wine (such as vodka) or biomass fuel.
Introduction to rice storage
After long-term storage of rice, due to the influence of temperature and moisture, the starch, fat and protein in rice will undergo various changes, which will make rice lose its original color, aroma and taste, reduce its nutritional components and edible quality, and even produce toxic and harmful substances (such as aflatoxin). Storage time, temperature, moisture and oxygen are the main factors that affect rice aging, and rice varieties, processing accuracy, bran powder content and insect damage are also closely related to rice aging.
The aging speed of rice is proportional to the storage time, and the longer the storage time, the heavier the aging. High moisture content, high temperature, poor processing accuracy, and more bran powder make rice aging faster. Among different types of rice, glutinous rice is the fastest aging, followed by japonica rice, and indica rice is slower. Therefore, in order to maintain the fresh quality and palatability of rice, attention should be paid to reducing storage time and keeping it cool and dry. The storage temperature of rice should be below 15℃, the relative humidity should be 75%, and the best storage condition is the balanced moisture of rice 14.5%.
