Chitosan is a useful derivative of chitin. It is formed through N-deacylation of the chitin molecule. In many papers, chitin and chitosan are used almost interchangeably. Chitin and chitosan are natural resources waiting for a market. They are refined from the waste products of the crabbing and shrimp industry.
Chitin is produced from the processing waste of shellfish, krill, clams, oysters, squid, and fungi.
The following is a chronolgical order of the processes needed to produce chitosan from crustacean shells. Chitosan Additionally, cartenoproteins can be extracted from crustacean wastes during this process for use in the production of aquacultured fish. Areas of Usefulness for Chitin and Chitosan Many areas have been investigated to find possible uses for these polymers over the years. The remainder of this page will focus on the biomedical uses. Biomedical Uses of Chitin and Chitosan Wound Healing Chitin has been found to have an acceleratory effect on the wound healing process.
