Chitosan is a biopolymer derived from chitin. The physicochemical properties of chitosan end products resulted from many factors such as chitin source of origin, deacetylation conditions such as alkali concentration, ratios of chitin to alkali, temperatureand extent of the reaction. The objective of this study was to investigate the effects of deacetylation time length and alkali treatments on physicochemical properties of chitosan products prepared from shrimp shell, and squid pen. The result demonstrated that the % yield of chitosan products were in the range of 62.23-90.83% for α form and 71.30-98.07% for β form. The molecular weight (MW) of chitosan products were in a range of 342.98-1603.48 kDa for α form, and 127.11-908.18 kDa for β form. The % deacetylation degree (%DD) of chitosan products derived from shrimp shell were in a range of 85.36-91.39%. In addition, the result showed that %DD of chitosan products was significantly negative correlated with MW of chitosan products.
