Physicochemical and biological properties of chitosan derivatives with varying molecular weight produced by chemical depolymerization

Chitosan derivatives with lower Mw were prepared by chemical depolymerization using hydrochloric acid. This modification improves functional and biological properties of shrimp chitosan and facilitates its utilizations. The obtained chitosan depolymerization products (CDP) were characterized in term...

Description
Summary:Chitosan derivatives with lower Mw were prepared by chemical depolymerization using hydrochloric acid. This modification improves functional and biological properties of shrimp chitosan and facilitates its utilizations. The obtained chitosan depolymerization products (CDP) were characterized in terms of molecular weight (Mw), degrees of acetylation (DA) and polymerization (DP), solubility, viscosity, crystallinity, and FTIR spectroscopy. High Mw-CDP (from 94.10 to 396.46 kDa) and low Mw-CDP (
