Do not expose rice worms to the sun.

Because the moisture content in rice is an important factor in measuring rice quality, rice with a moisture content of about 15% has the best eating quality and is more durable for storage. Exposing rice to the sun will cause the internal water in the rice to evaporate quickly, causing the inside and outside of the rice grains to shrink out of balance, resulting in the phenomenon of "exploding waist". The so-called burst waist refers to the horizontal or vertical cracks in the rice.

Rice contains about 75% carbohydrates, 7%-8% protein, 1.3%-1.8% fat, and is rich in B vitamins. The carbohydrates in rice are mainly starch, and the protein contained is mainly rice glutenin, followed by rice glutenin and globulin. The biological value of its protein and the proportion of amino acids are higher than those of wheat, barley, millet, corn and other cereal crops. High, with a digestibility of 66.8%-83.1%, it is also the highest among cereal proteins.
