Chitosan

Character:
Chitosan, unsolved in water but tenuous acid and absorbed in body is abstracted from chitin.As the first derivation, it, with chemical structure of alkyl polysaccharide polymer with cation, has peculiar physical and chemical capability and biological activating function.
Application:
The products can mostly applied in textile, printing, leather, cigarette, plastics , foodstuff, fodder, color film, medicine, and paper manufacturing industry, biological engineering industry, agriculture protecting industry , dirty water cleaning industry, etc . Depending on the different viscosity , in particular, chitosan owing to the characters naturally activating capability without virulent and side effect, absorbed in body, reducing heavy metal, adjusting pH in body,improving the immunity, strongthening the liver function,ameliorating digestion, abasing fat and sugar, restaining cancer occuring, and expelling heavy metal out of body, is greatly applied as the food protcting health and the medicine additive.
