Raw rice contains a lot of vitamins and protein. Under normal circumstances, raw rice can't be eaten. Eating raw rice often may cause indigestion and gastrointestinal discomfort. Cooked rice can fully release the nutrition of raw rice, which is easy to attract people.

Rice contains about 75% carbohydrates, 7%-8% in protein, 1.3%- 1. 8% fat and rich in B vitamins. The carbohydrate in rice is mainly starch, and the protein in rice is mainly glutenin, followed by glutenin and globulin, which is a kind of advanced cereal protein.

Tips for choosing rice:

1. Look at the hardness: the hardness of rice is determined by the content of protein. The hardness of rice is stronger, the protein content is higher and the transparency is better. New rice is harder than old rice, rice with low water content is harder than rice with high water content, and late indica rice (japonica rice) is harder than early indica rice (japonica rice)

2, look at the white belly: there are often opaque white spots on the abdomen of rice. White spots are called heart white in the central part of rice and outer white in the outer abdomen. Belly white rice is low in protein content and contains more starch. Rice with high water content, immature and immature after harvest has a big white belly.

3, look at waist explosion: waist explosion is caused by the loss of balance inside and outside after the rice grains suddenly appear heated during the drying process. Fried rice tastes rotten and endogenous, and its nutritional value is reduced. Therefore, when selecting rice, we should carefully observe the surface of rice grains. If one or more transverse cracks appear on the rice grain, it means that it is a waist-popping rice.
