How to see the standard of 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. Generally, new rice is harder than old rice, low water decimeter is harder than high water decimeter, and late indica rice is harder than early indica rice.

2. Look at the white belly: there is often an opaque white spot in the belly 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. Generally, rice with high water content, immature rice and immature rice after harvest has a big white belly.

3. Look at waist explosion: waist explosion is caused by internal and external imbalance after rice grains suddenly appear heated during drying. Fried rice tastes rotten and endogenous, with low nutritional value. 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.

4. Look at the yellowing of rice grains: The yellowing of rice grains is caused by chemical reactions of some nutrients in rice under certain conditions, or by rice microorganisms. These yellow grains lack country flavor and food flavor.

5. Look at Xin Chen: The aging of rice is serious, the color of old rice becomes darker, the viscosity decreases, and the original flavor of rice is lost. Therefore, we should carefully observe the color of rice grains. The rice with gray powder or white grooves on the surface is old rice, and the more it is, the older it gets.
