Extraction of Chitin and Chitosan from Marine Waste and its Applications on Food and Agriculture Products

Chitin and chitosan are linear polysaccharides, structurally similar to cellulose, and have a set of unique characteristics such as biocompatibility, biodegradability to harmless products, non-toxicity, physiological inertness, antibacterial properties, heavy metal ion chelation, gel-forming properties, and, hydrophilicity and remarkable affinity to proteins. The motive of this review was to provide a literature review about chitin and chitosan. And also gives scientific research information about the context. This review reveals the chemistry of chitin and chitosan, various marine sources, different extraction methods and the different applications of chitin and chitosan in the food and agriculture industry.
