Molecular formula: (C6H11NO4)n

Chemical name: β-1,4-poly-D-glucosamine

CAS No.: 9012-76-4

Character:

Off-white, innocuous, flavourless semitransparent and amorphous solid with pearly color. Insoluble in water, dilute acid, dilute alkali. Insoluble in water or alkali solution, soluble in inorganic acid like diluted hydrochloric acid and nitric acid. and most organic acid. In diluted acid solution, backbone chain of chitosan will hydrolyze slowly.

Applications:

Food chitosan made by our company is made from unpolluted Alaska deep-sea crab shell with the processing techniques of decalcification, deproteinization, decolorization and deacetylation. For its nice appearance and excellent quality, it's the optimal choice for medicine, health care products and food.

Chitosan is awarded as the 6th life essence for human being besides glucide, protein, adipose, vitamin and minerals. Chitosan plays an important role in the physiological activities. Widely used in the following fields: medication, health food, food, feed, cosmetic, color film, bioengineering, agriculture, sewage treatment. textile, dyeing, leather, dope, tobacco, plastic.

(1). In medicine and healthcare field:  chitosan is widely applied for its multi-function of improving immunity, activating cells, preventing cancer, decreasing blood fat and blood pressure, adjusting blood sugar, fighting against aging and adjusting organism environment .

(2). In functional material field, chitosan can be applied in membrane material, carrier, sorbent, fiber and medical materials.

(3). In environment protection field, chitosan can be applied in waste water disposal, protein recycle and water purification.

(4). In light textile field, chitosan can be applied in fabric sorting, healthcare underwear and paper making additives. 

(5). In agriculture field, chitosan can be applied in feedstuff additive, seed disposal, soil amelioration and fruit refresh-keeping etc.

(6). In tobacco field, for its characteristics of improving taste, non-poisonous and odorless burning, chitosan can be applied as tobacco slice glue.
