Analysis:

When cooking rice, you should wash the rice first, and wash the sand and sundries mixed in the middle of the rice. But there is no way to wash rice. When washing rice, the nutrients on the surface of rice are easily lost with water.

The experiment shows that after washing rice in water once, protein content will be lost by 4%, fat loss 10% and inorganic salt loss by 5%.

The correct way to wash rice is:

1. Wash rice with cold water, not with hot water and running water.

2. Properly control the times of elutriation so as to elutriation sludge and debris.

3. Taomi can't be rubbed hard.

4. Don't soak rice in water before washing rice to prevent a large amount of soluble nutrients on the surface of rice grains from losing with water.
