Introduction to Chitin/Chitosan

Chitin is the second most abundant biopolymer in the world next to cellulose. Chitin exists widely in the exoskeleton of insects and other marine crustaceans and cell walls of fungi. Chitin and chitosan gathered wide attention in the fields like environment, agriculture, medicine/pharmacy, food science, biotechnology and nanotechnology etc. due to its biodegradability, biocompatibility, antimicrobial activity, non-toxicity and versatile chemical and physical properties. Various derivatives of these biopolymers in the form of flakes, fibers, beads, composites, membranes, nano powders, templates etc have been prepared and found application in the above said fields and a few chitin/chitosan based products were commercialized.
