The reason is that some molds are harmless to people. Tofu with a layer of moldy hair on it is called hairy tofu. The moldy hair is not really moldy. The thick and pure white hair has some black particles evenly distributed on it, which is a spore and a sign of the maturity of hairy tofu.

Extended data:

Sufu does have a disadvantage, that is, it must put a lot of salt to help preserve it. The salt content of sufu products varies with varieties, and the average sodium content of most products can reach 2-3%, which is equivalent to 5-7.5% salt. Although the saltiness of sufu block itself is lower than that of sufu, the weight of a large block is about 20 grams, and that of a small block is about 10 grams, so the total salt intake is still considerable.

If the salt content is 5%, 20 grams of soy bean curd is equivalent to 1 gram of salt. Therefore, if you want to enjoy the nutritional value and health benefits of sufu, you should use it to replace the salt in three meals, instead of eating two pieces of sufu while eating the same amount of salt.

Replacing part of salt with sufu can increase the supply of nutrients, including a little calcium and magnesium, and peptides that are beneficial to controlling blood pressure, while not increasing the total sodium. Sufu is not as unhealthy as we thought. Please feel free to eat it.
