Long-haired tofu is different from mildew. Long hair is edible.

Tofu can be eaten after long hair, but you must use brine. Because brine has bactericidal effect and can be preserved for a long time, we will eat tofu milk. So moldy tofu is harmless to human body. It is also wrong to say that moldy tofu can cause cancer, because moldy tofu and steamed bread fermentation are the same, not harmful bacteria fermentation.

Tofu is moldy and can't be eaten.

Because moldy food will produce many harmful microorganisms and bacteria, such as Aspergillus flavus, nitrite, typhoid Bacillus, Salmonella, cholera Bacillus, Escherichia coli, parahemolytic Bacillus, Clostridium botulinum and other bacteria, which can cause poisoning, such as nausea, vomiting, diarrhea, dizziness, dizziness and so on. The worst is life-threatening. Of course, some foods taste better and are more nutritious through mildew, such as yogurt and tofu milk.

Tofu is not sold until it grows.

It is hot in Yunnan, so it is difficult to keep food fresh. Many people in Yunnan also like to eat stinky tofu, so they simply cover the freshly made tofu with straw for a few days until the long hair turns into stinky tofu and then sell it on the street. It is said that Emperor Kangxi of the Qing Dynasty tasted the stinky tofu in Yunnan and was very happy. He named it "Fang Qing stinky tofu". As a result, tofu stalls in central Yunnan, southern Yunnan and western Yunnan spread all over urban and rural areas. Stinky tofu can also be fried, fried, steamed or pickled into fermented bean curd, which is a unique local food in Yunnan.
