CAS No.: 9012-76-4
Origin: Alaska Crab Shell/shrimp shell
Chitosan is a Off-white powder,flavorless semi-transparent and amorphous solid. Soluble in acid, but insoluble in alkali and water or in ordinary organic solvent. Decomposed at 185°C.Chitosan is produced commercially by deacetylation of chitin by treating crabs and shrimp with the alkali sodium hydroxide it is a kind of unique fat-absorbing dietary fiber.
The molecular weight of Chitosan: Chitisan is a deacetylated dervative from chitin,widely used in biomedical, food industry,chemicals. high molecular weight and low molecular confine their usage: high molecular weight chitosan exhibit high viscosities in aqueous solutions,the lower molecular weight of chitosan have a better solubility in neutral aqueous solutions, the lower one have a more wide application for usage.Our factory produce lowder molecular weight of chitosan by treatment high molecular weight chitosan according to buyer's requests and specific application.
