Description

Chitosan, also known as deacetylated chitin, is obtained by deacetylation of chitin, which is widely present in nature. Its chemical name is polyglucosamine (1-4)-2-amino-B-D glucose. Since 1859, when Frenchman Rouget first obtained chitosan, the excellent properties of this natural polymer, such as biofunctionality, compatibility, blood compatibility, safety, and microbial degradability, have attracted wide attention from all walks of life. Significant progress has been made in the application research in many fields such as medicine, food, chemical industry, cosmetics, water treatment, metal extraction and recovery, biochemistry and biomedical engineering. For patients, there are research reports on the effect of chitosan in lowering blood lipids and blood sugar. At the same time, chitosan is listed as a thickener and film-forming agent in the national food additive use standard GB-2760.

Chitosan is the product of chitin deacetylation. Generally speaking, chitosan is the product of chitin with more than 55% N-acetyl removed. In other words, chitosan is the product of chitosan with 1% N-acetyl removed. In other words, chitosan is the product of chitosan with 1% deacetylation dissolved in 1% acetic acid or 1% hydrochloric acid. In fact, chitosan with an N-deacetylation degree of more than 55% can be dissolved in such dilute acid. As an industrial product, chitosan has an N-deacetylation degree of more than 70%. Chitosan with an N-deacetylation degree of 55% to 70% is low-deacetylation chitosan, chitosan with a N-deacetylation degree of 70% to 85% is medium-deacetylation chitosan, chitosan with a N-deacetylation degree of 85% to 95% is high-deacetylation chitosan, and chitosan with a super-high-deacetylation degree of 95% to 100% is super-high-deacetylation chitosan. Chitosan with an N-deacetylation degree of 100% is extremely difficult to prepare. Each sugar group of chitin may or may not have N-acetyl groups. Any chitin with an N-acetyl degree below 50% is called chitin because it is definitely insoluble in the above concentration of dilute acid.
