What is Chitosan?

Chitosan is a deacetylated derivative of chitin. It is polysaccharide with an amino group found in nature, contained in the shells of crustacean such as crabs, shrimps and etc. Chitosan is a white to light-red solid powder, insoluble in water, soluble in acid, but indigestible by human digestive enzyme. Therefore, it is one of the so-called dietary fibers.

Manufacturing method

Generally, chitosan is produced from the shells of crabs and shrimps. After the shells are deproteinized in a diluted sodium hydroxide solution, decalcium in a diluted hydrochloric acid to produce chitin. The chitosan is produced from chitin by deacetylation in a heated concentrate sodium hydroxide solution, thereby yielding the targeted chitosan substance.
