Abstract
imported samples. Chitin and chitosan extracted from local shrimp shells contained 0.74% and 2.50% fat, respectively. Chitosan extracted from imported shrimp shells had a fat content of 7.307%. Fresh shrimp yielded 14.04% of chitosan, with a 0.329% the chitosan extracts from the local shrimp shells, compared to 8.5% extracts from the imported shrimp shells. A deacetylation score of 9.944 was found in chitosan extracted from both local and imported chimpanzees. The solubility of chitosan extracted from domestic shrimp shells was 0.329%, against an 8.5% solubility of chitosan extracted from imported shells. The solubility of locally extracted chitosan is, therefore, comparatively weaker. The water-binding capacity (WBC) of chitosan extracted from local and imported shrimp shells were found to be 485.6% and 483.2%, respectively. The ability of chitosan extracted from local shrimp shells showed a fat binding capacity (FBC) of 611% against a capacity of 764% of imported chitosan. Although this study succeeded in extracting chitin and chitosan from local and imported shrimp shells using chemical treatment, chitosan production was significantly poor, compared to previous studies.
