Abstract

Hydrochloric acid has been the conventional acid of use in shrimp shell demineralization for chitosan synthesis. This inorganic acid was compared to acetic acid; an organic acid in the demineralization stage. Deproteinization and deacetylation stages were carried out using a sodium hydroxide solution to produce chitosan. Characterization using Fourier Transform Infrared Spectroscopy (FTIR) showed the structure and functional groups of the synthesized chitosans, while X-Ray Diffractometry (XRD) and Scanning Electron Microscopy (SEM) were used to investigate the crystallinity and structural differences respectively. From the analysis, chitosan property was compared at the molecular weight, viscosity, solubility and Degree of Deacetylation (DD) (85% when acetic acid was used, and 87.06% when HCl was used).  Experimental analysis indicated that acid type did not significantly affect properties of synthesized chitosan.
