The embryo and aleurone layer of rice contain nearly 64% of rice nutrition and more than 90% of essential nutrients for human body, which is relatively balanced, which should be the fundamental reason why it has become a staple food for human beings. The newly patented product Mizhen is a clean and nutritious food based on rice germ and aleurone layer. It is an upgraded product of rice bran and will become the main product of rice processing industry. Rice is the basic food to supplement nutrients. In addition to rich carbohydrates, it also contains protein, fat, vitamins and 11 minerals, which can provide more nutrition for the human body. Although the individual content of various nutrients is not very high, they are generally of high nutritional efficacy due to their large consumption.
Rice contains about 75% carbohydrate, 7% - 8% protein, 1.3% - 1.8% fat, and rich B vitamins. The carbohydrate in rice is mainly starch, and the protein in rice is mainly glutelin, followed by glutelin and globulin. The biological value and amino acid composition of the protein are higher than those of wheat, barley, millet, corn and other cereal crops. The digestibility is 66.8% - 83.1%, which is also a higher type of cereal protein.
Therefore, eating rice has high nutritional value. However, rice protein contains less lysine and threonine, so it is not a complete protein, and its nutritional value is not comparable to animal protein. But eating rice at lunch and dinner is more conducive to people's weight loss than pasta. In the south of China, people generally eat rice as their staple food, while in the north, it is very different.
The fat content is about 9%, and the linoleic acid content in the fat is relatively high, generally accounting for 34% of the total fat, 2-5 times more than that of Lai seed oil and tea oil respectively.
Rice, grain (millet), millet (sorghum), wheat and beans are called "five grains". (Rice is unprocessed rice.).
