How to refine chitin 20, how to refine chitin

The first method: all say "small profits", experts say, in fact, not only can protein powder be extracted from fly maggots, but also chitin extracted from fly maggots is currently the highest in the world market, selling at a sky-high price of $27 per gram.

In fact, the chitin extracted from fly maggots is the best quality.

Such chitin not only has the best health care function, but also is the best raw material for the manufacture of "artificial **" and clothing, because of the scarcity of resources, so the ** in the international market is also the most expensive, last year it was sold at a sky-high price of 55 US dollars per gram, and this year's market ** has declined slightly, but the ** per gram is also about 27 US dollars, a ton ** is very considerable.

Due to the small number of people who know fly maggots, there are many people who think that fly maggots are dirty and disgusting, so fly maggots have been in short supply on the market.

Fly head is not a small profit, point fly can be gold.

Jiang Xihua said that in the eyes of people, flies are the first to spread diseases, useless, in fact, flies live in a bacterial environment, and do not carry bacteria themselves, and the reason why it spreads diseases is because the fluff on the fly's feet will bring bacteria to food and spread to people.

Scientists have found inspiration from the flies' own super resistance to bacteria, and through research, they have found that "antimicrobial peptides" can be proposed from flies, which is a natural "antibiotic", and the shells shed by fly maggots are currently recognized as the best raw materials for the production of chitin.

In fact, flies are full of treasures, and the skin of fly maggots can produce chitin and chitosan; The pulp of maggot crushing can separate "antimicrobial peptides" with high bactericidal effect; Maggot oil can be used in cosmetics and health care products; Maggot pulp protein has a good amino acid balance suitable for human absorption, which can be made into health products. Flies are particularly fertile and have a short growth cycle.

The second method:

Chitin is a substance that occurs naturally in crustaceans such as crabs.

Lobster shells are extracted from chitin.

There are many ways to refine!

There are many methods in the chemical industry.

The hard part is synthesis.

This is a very broad question.

You should find a chemical department to discuss it together.

It is mainly divided into two parts:1After grinding the crustaceans, the inorganic salts such as calcium carbonate are removed with acid;

2.Next, the protein is removed with dilute lye or enzyme treatment, and all that remains is chitin.

You can also refer to Jiang Tingda's book "Chitin", although it is a bit old, but the method is still practical.

As for the purpose, I think it is mainly for the preparation of chitosan, after all, this is more eye-catching in scientific research. If you encounter the above problems in the process of scientific research, it is better to consult the literature.

Hope that helps!
