1) Try to reduce the number of rice washes, generally not three times, and it is not advisable to rub rice vigorously. Cold water should be used to wash rice, and the soaking time should not be too long.

(2) Don't eat "fishing rice", that is, take out the rice until it is half cooked, then steam it, and throw away a lot of B vitamins dissolved in rice soup. Cooking rice should be done by steaming and boiling. If cooking rice, rice soup should also be drunk.

(3) Do not add alkali when cooking. Because alkali can easily accelerate the destruction of vitamin C and B vitamins. Generally, when making pasta, the loss of B vitamins caused by steaming, roasting and burning is small, but it is greater when frying at high temperature.
