ABSTRACT
Chitin is a natural polysaccharide that was rst identied in 1821. Henri Braconnot who is the director of the botanical garden in France observed a material in mushrooms that did not dissolve in sulfuric acid. Braconnot named it as fungine. In the late 1830s, it was isolated from insects, and in 1859, chitosan, a derivative of chitin, was produced (Nicol, 1991).
