Chitosan: Sources, Processing and Modification Techniques

Gels, Journal Year: 2022, Volume and Issue: 8(7), P. 393 - 393

Published: June 21, 2022

Chitosan, a copolymer of glucosamine and N-acetyl glucosamine, is derived from chitin. Chitin found in cell walls crustaceans, fungi, insects some algae, microorganisms, invertebrate animals. Chitosan emerging as very important raw material for the synthesis wide range products used food, medical, pharmaceutical, health care, agriculture, industry, environmental pollution protection. This review, line with focus this special issue, provides reader (1) an overview on different sources chitin, (2) advances techniques to extract chitin converting it into chitosan, (3) importance inherent characteristics chitosan that makes them suitable specific applications and, finally, (4) briefly summarizes ways tailoring applications. The review also presents influence degree acetylation (DA) deacetylation (DDA), molecular weight (Mw) physicochemical biological properties acid-base behavior, biodegradability, solubility, reactivity, among many other determine processability suitability intended help guide researchers select right their

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

Journal of Agriculture and Food Research, Journal Year: 2024, Volume and Issue: 16, P. 101164 - 101164

Chitosan is a cationic polysaccharide and derived from chitin present in exoskeleton of crustaceans such as prawns, crabs, lobsters. This natural biopolymer chemical structure identical to cellulose but insoluble aqueous organic solvents. an ecologically beneficial biodegradable alternative synthetic polymers, notably typical plastics. may be used make variety films, coatings, membranes, each having its own distinct features. films are biodegradable, translucent, have high mechanical strength, making them adequate for food packaging, water purification, wound dressings. Chitosan-based coatings often packaging foods fruits vegetables, meat, seafood. According the findings, chitosan outstanding barrier qualities against UV radiation, gases, moisture. They can assist safeguarding packed objects outside influences oxidation humidity, which could degrade their quality. Chitosan's antibacterial naturally limit development bacteria, viruses, fungi. Because this property, chitosan-based useful perishable products since they extend shelf life by lowering microbial contamination. Modifying content or adding additional components change strength flexibility film. Surfaces treated with improve resistance, properties, activity. review article discusses different approaches solvent casting, extrusion, electrospinning, thermoplastic method, layer-by-layer assembly, spraying, dipping preparation coatings. Further these material properties viscosity, thermal optical solubility, hydrophobicity, color, characteristics, qualities, antioxidant activity prolonging described depth.
