What is bean skin?

Bean skin, also called bean curd skin, is made of soybean. The nutritional value of soybean protein, dietary fiber and carbohydrate is similar to that of soybean, which is very beneficial to human body. The disadvantage of tofu skin is the lack of an essential amino acid-methionine. If it is combined with some other foods, such as fish, eggs, kelp, ribs, etc., the utilization rate of protein in tofu skin can be improved and the taste is more delicious.
