Production and characterization of Chitosan from shrimp shells waste

Abstract

This research aims to study the production of chitosan from shrimp shell waste origin and characterize the chitosan quality of shrimp shell waste that includes parameters yield, solubility, intrinsic viscosity, molecular weight and deacetylation degree. Results showed that the treatment of heating temperature and heating time in the process of deacetylation caused significant (P≤0.01) influence on yield, solubility, intrinsic viscosity, molecular weight and deacetylation degree of produced chitosan. Whereas, the interaction between heating temperature and heating time on the process of deacetylation gave no significant effect on yield, solubility, intrinsic viscosity, molecular weight and deacetylation degree of chitosan produced. The best results in this study were obtained from heating temperature of 100°C and 80 min heating time.
