The rice is a finished product prepared by the working procedures of rice cleaning, rice hulling, rice milling, finished product finishing and the like. The embryo and aleurone layers of the rice contain nearly 64 percent of rice nutrition and more than 90 percent of nutrient elements required by human bodies, and are main food for southern people. The rice contains about 75% of carbohydrate, 7% -8% of protein, 1.3% -1.8% of fat and rich B vitamins. The carbohydrate in the rice is mainly starch, the protein is mainly glutelin, and secondly gliadin and globulin, the biological value of the protein and the composition ratio of amino acid are higher than that of cereal crops such as wheat, barley, millet, corn and the like, the digestibility is 66.8-83.1%, and the carbohydrate is also one of the cereal proteins. Therefore, the edible rice has higher nutritional value. However, rice protein contains less lysine and threonine, and thus is not a complete protein and has a nutritional value comparable to that of animal protein. But the rice is more beneficial to losing weight compared with cooked wheaten food when being eaten in lunch and dinner. In southern areas of China, people generally eat rice as staple food, but in northern areas, there are great differences. The fat content is about 9%, and the linoleic acid content in the fat is higher, generally accounting for 34% of the total fat, and is 2-5 times more than that of the rapeseed oil and the tea oil respectively.
