[0002] Rice is a finished product made from rice grains after cleaning, husking, milling, and finishing. The germ and endosperm of rice contain nearly 64% of rice nutrition and more than 90% of the nutrients required by the human body. It is the main food of the people in the south. Rice has extremely high nutritional value and edible value. With the advancement of technology, rice is not only eaten as a staple food, but also processed into other types of products.
