Some businessmen buy hair in the rural market. What do they do with it?

Hair is a kind of keratin substance. After chemical treatment and hydrolysis into high concentration hydrochloric acid, it can decompose 28 amino acids and produce a large number of animal nutrient solutions and feed additives. This is also the reason why amino acids decomposed in hair can be used as nutrient solution and food additive. About 20 ~ 30 years ago, there was soy sauce in China. At that time, wool collectors often went to the countryside to buy. With the improvement of people's living standards, the phenomenon of paying more attention to nutrition and health gradually disappears. Now the hair has been bought and made into wigs, folds and decorations.

In addition, hair can absorb oil. In 20 10, an oil spill occurred in the Gulf of Mexico, and the American people began to collect wool. Barbers and beauty salons put their hair in stockings, where oil leaks, and use it to absorb oil. Surprisingly, 1 lb (453.59g) of hair can absorb 1 gallon (3.79L) of oil.

I remember when I was a child, people in our local countryside would open the door every once in a while to collect hair, usually women's hair, and the price of hair was determined according to the quality and length of hair. Women generally love beauty and don't cut their hair easily, but at that time, the price of hair was still very high and everyone wanted to sell it.

The first thing to know is that hair is keratin. After chemical decomposition, more than 20 amino acids can be decomposed, which can be used for mass production of animal nutrition and animal feed additives. Hair is rich in protein.

In fact, most of us used to know that most of the hair collected at high prices in rural areas was used to make wigs. When you think of ancient drama or drama, you need a lot of wigs. Ancient people all had long hair, so the demand was relatively large. The acting skills in some Beijing opera plays are also inseparable from wigs, and even beards need hair to look real.

There is a growing demand for wigs in modern society. Because recently many men have baldness when they are young. We often see bald men wearing wigs. What you don't know must be a wig. This is actually made of real hair. It may be because we often love beauty and need to work, so we often change our hair styles, but if it is our own hair, it is easy to break, so wigs are the best props.

Make synthetic soy sauce. Human hair contains a lot of protein, which is decomposed to extract amino acids and protein. Many illegal soy sauce enterprises use this chemically synthesized "hair water" to make soy sauce in order to meet the standards of amino acids and protein in refueling. This chemical synthetic refueling is very harmful to human health. Nowadays people often wash their hair and dye it, so there is a lot of arsenic left in their hair. In particular, the content of heavy metal lead often exceeds the standard. The use of this chemically synthesized soy sauce will lead to excessive intake by the human body and easily lead to health problems. I hope you don't do such immoral things.
