This is fake soy sauce, made from human hair, salt, etc. as raw materials.

First dissolve the hair in a certain liquid (I have forgotten the specific liquid), then add salt and other substances to make a soy sauce flavor. However, this kind of "soy sauce" is not edible by humans (it contains bacteria and poison)

Theoretically it is possible:

Traditionally, soy sauce is made by fermenting soybean protein. The main component of hair is protein, and it is easy to hydrolyze it into amino acids to make soy sauce. This can save a lot of soy raw materials. Of course, the composition of various amino acids hydrolyzed from hair protein is definitely different from the composition of various amino acids hydrolyzed from soy protein, which may affect the flavor of soy sauce. Scientifically speaking, it is believed that soy sauce for hair can be eaten, but

we don’t want to eat dust, dirt, shampoo, shampoo, hair dye, etc. at the same time. We Chinese people are mean-spirited, but It's not a trash can either.

This is what black-hearted manufacturers do:

The procedure for producing amino acid mother liquor is to boil hair in hydrochloric acid, then neutralize it with alkali, filter it with a vacuum pump, and filter it out black The light red liquid underneath the lumpy object is the raw material for making soy sauce. The reporter then interviewed staff from the Quality Department of the Jilin Municipal Bureau of Quality and Technical Supervision. According to reports, the state has mandatory regulations on the production process and raw material configuration of soy sauce products. Using human hair as a raw material for soy sauce production does not comply with relevant regulations.
