Background
The rice is made by hulling the seeds of the rice, contains nearly 64 percent of nutrient substances in the rice and more than 90 percent of nutrient elements required by human bodies, and is a main food for people in most regions of China. Rice is essential for both family meals and restaurants. From the aspect of nutrition, the rice can provide rich B vitamins, and has the effects of tonifying middle-jiao and Qi, strengthening spleen and stomach, replenishing vital essence and strengthening mind, regulating five internal organs, promoting blood circulation, improving hearing and eyesight, relieving restlessness, quenching thirst and stopping diarrhea, and the rice porridge has the effects of tonifying spleen, harmonizing stomach and clearing lung-heat.
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. The traditional Chinese medicine considers that the rice is sweet and neutral in taste, has the effects of tonifying middle-jiao and Qi, strengthening spleen and stomach, replenishing vital essence and strengthening mind, harmonizing five internal organs, promoting blood circulation, improving hearing and eyesight, relieving restlessness, quenching thirst and stopping diarrhea, is called as the first of five cereals, is a main food crop in China, and occupies about one fourth of the cultivation area of the food crop. Rice is the staple food for half of the world population. The rice, entering spleen, stomach and lung channels, has the functions of invigorating spleen and replenishing qi, nourishing yin and moisturizing lung, strengthening spleen and stomach and removing polydipsia.
