Chitosan is a polycationic polymer containing more than 5000 glucosamine units and is obtained commercially by alkaline deacetylation of chitin (a N-acetyl-glucosamine polymer) from shellfish exo-skeletons. Chitosan is inexpensive, non-toxic and possesses potentially reactive amino functional groups. It has been shown to be of potential use in many different fields: as an antifungal compound in agriculture, as a flocculating agent in wastewater treatment, as a food additive in food industry, as a hydrating agent in cosmetics, and more recently, as a pharmaceutical agent in biomedicine. It is known to have a marked hypocholesterolemic effect in cholesterol-fed rats, lowering cholesterol absorption in the lymphatic thoracic duct.

Packing: for medical and food degree:15kg, 20kg, 25kg/fiber drum *①We can supply high pure chitosan with ≥95.0% deacetylation degree *② The viscosity is determined at 20.0℃ with 1%chitosan in 1.0% acetic acid.The application of chitosan is different with that of quality. We can supply chitosan with differentquality as required.
