title = "Water-soluble chitosan from waste swimming crab shell (Portunus pelagicus)",
abstract = "Water-Soluble Chitosan (WSC) has been successfully synthesized from local swimming-crab shell (Portunus pelagicus) waste. Chitin was obtained from demineralization and deproteinization of swimming-crab shell. Chitin was converted to chitosan via deacetylation reaction that carried out using NaOH 50% (w/v) at varied temperatures. The highest deacetylation degree was 73.10% when the reaction was carried out at 100°C for 10 hours. WSC was obtained by the depolymerisation reaction of chitosan with H2O2 30%. The highest WSC rendemen obtained was 94.67%. The solubility test of WSC at 40°C in HCl 0.1 M and water were 0.79 mg/mL and 1 mg/mL respectively.",
