A thorough evaluation of chitosan-based packaging film and coating for food product shelf-life extension

Chitosan is a cationic polysaccharide and derived from chitin present in exoskeleton of crustaceans such as prawns, crabs, and lobsters. This natural biopolymer chemical structure is identical to cellulose but insoluble in aqueous and organic solvents. Chitosan is an ecologically beneficial biodegradable alternative to synthetic polymers, notably typical plastics. Chitosan may be used to make a variety of films, coatings, and membranes, each having its own distinct features. Chitosan films are biodegradable, translucent, and have high mechanical strength, making them adequate for food packaging, water purification, and wound dressings. Chitosan-based films and coatings are often used for packaging foods such…
