ANY OTHER RELEVANT INFORMATION: Chitosan is usually prepared from chitin found in a wide range of natural sources, crustaceans, fungi,<br />

insects, annelids, molluscs, coelenterata. However, chitosan is only manufactured from crustaceans<br />

(crab, krill and crayfish), primarily because a large amount of the crustacean exoskeleton is available as<br />

a byproduct of food processing.<br />

Chitosan from mushroom and squid pens may soon be available commercially<br />
