- Abstract
The crab shell waste contains many chitins. When it processed in several chemical processes, it can produce chitosan, which has many benefits and economic value. Chitosan is a linear polysaccharide that consists of N-acetyl glucosamine and D-glucosamine monomers. This study aims to determine the optimum condition of temperature and time of the deacetylation process from the chitin crab shell (Portunus pelagicus) to be chitosan. There are three stages of making chitosan; deproteination, demineralization, and deacetylation. In the deproteination process, crab shell powder was added with a 3.5% NaOH at 65 oC while being stirred for 2 hours. In the demineralization process, crab shell powder was added by 1 N HCl solution for 30 minutes at room temperature. The deacetylation process was done by heating the chitin with NaOH 50% solution with a ratio of 1:10 (w/v) at 90o C for 2 hours. In every step of making chitosan when the stirring has been completed, then it’s neutralized using aqua dest and dried in the oven for 24 hours. Chitosan that produced has the highest degree of deacetylation is 79.68%.
