Chitin & Chitosan Derived from Shrimp’s Shell of Persian Gulf
Biopolymers with no toxicity,
biodegradable and biocompatible with several ten of applications
Chitin is one of the most abundant polysaccharides found in nature. It is found naturally in the shells of crustaceans, insect exoskeletons, fungal cell walls, micro fauna and plankton. It is found in association with proteins and minerals such as Calcium Carbonate. Chitosan is a useful derivative of chitin. It is formed through N-deacylation of the chitin molecule.
Chitin was extracted at Iran Polymer & Petrochemical Institute from Persian Gulf shrimp’s shells. This powder is being named as Persian Gulf Chitosan (PGC). The key parameters obtained from the elemental analysis are shown in the below table. The degree of deacetylation (DD) is determined from the nitrogen percent of the Chitosan samples.
DD of PGC was 90-99% and MV around 1.03-5.31×105 .
