Abstract Water-Soluble Chitosan (WSC) has been sucessfuly synthesized from squid pens waste. The synthesis of chitosan from chitin was carried out by optimization of deacetylation temperature and time. Chitin was obtained from squid pens waste by demineralization and deproteinization process. HCl 7% was used for demineralization and NaOH 10% at 60°C was applied for deproteinization process. Deacetylation reaction was carried out at varied temperatures i.e., 60°C, 70°C, 80°C, 90°C and 100°C in NaOH 50% solution for 10 hours. Deacetylation reaction time were varied for 2 hours, 4 hours, 6 hours, 8 hours, and 10 hours. The crude chitosan obtained then reacted… More >
