Product Description

Chitin for Chitosan
A survey of the crustacean

Chitin, English chitin, also known as chitin, chitin, etc.


Chitin is a nitrogenous polysaccharide biological polymer widely existing in nature. It is mainly derived from the shell of crustaceans such as shrimp, crabs and insects, and the organs of software animals (such as the cartilage of squid), as well as the cell wall of fungi. Its reserves in the Earth's natural polymers account for the second, estimated annual natural biological synthesis of up to 1 × 1011 tons, second only to cellulose.



Chitin, purified from shrimp and crab shells, contain a small amount of amines (-NH2) and most acetyl groups (-COCH3). Chitosan is insoluble in general weak inorganic acids or organic solvents, insoluble in lye, only soluble in strong inorganic acids, the dissolution process will occur molecular chain degradation.



The Chitin class

According to the use of different raw materials can be divided into high quality chitin, industrial grade chitin, etc.

According to the actual use of different products, it is necessary to choose different, different use.

Chitin structure:

Use of Chitin:

Chitin is the basic raw material for the production of chitosan, glucosamine hydrochloride, glucosamine sulfate and other products. It can also be used in food, chemical and other fields.

      Chitin is a polysaccharide extracted from the shells of marine crustaceans with the chemical formula (C8H13O5N)n. Chitin is light beige to white, soluble in concentrated sulfuric acid and acetic acid, insoluble in alkali and other organic solvents, and insoluble in water. Chitosan, a deacetylated derivative of chitin, is insoluble in water and partially soluble in dilute acids.

                Chitin has a wide range of applications and can be used in fabrics, clothing, dyes, paper and water treatment in industry. In agriculture, it can be used as pesticides and plant antiviral agents. Fish feed for fish farming. Cosmetic beauty agent, hair protection, moisturizing agent, etc. Medical supplies can be used for contact lenses, artificial skin, sutures, artificial dialysis membranes and artificial blood vessels, etc.
