[0002] Rice polishing is an important technological process, aiming to improve the appearance of rice, enhance its storage performance, and possibly optimize its taste. After brown rice is milled into rice, a small amount of bran powder remains on the surface of the rice grains. These bran powders not only affect the appearance of rice but also may affect its storage property and the taste of cooked rice. Polishing can effectively remove these impurities. Polishing makes the surface of the rice grains smoother, reduces the erosion of ultraviolet rays and oxygen, and thus extends the storage period of rice;
