Its chemical name is polyglucosamine (1-4) -2-amino-B-D glucose. Since 1859, the French Rouget first after get the chitosan, the biological functions and compatibility of the polymer, blood compatibility and microbial degradation is excellent properties such as wide attention from all walks of life, in food, chemical, cosmetic, water treatment, metal extraction and recovery, chemical, biological and biomedical engineering, and many other studies have made great progress in the field of application. At the same time, chitosan as a thickening agent, film agent listed in the national standard for food additives GB-2760.
