Abstract

The isolation chitosan generates the different characteristics of the product, depending on the raw material and isolation method. The focus of this research is to study the thermal and morphological characteristics of chitosan isolated from banana shrimp shells (Penaeus merguiensis de Man). The production of chitosan was started by the isolation of chitin from shrimp shells via deproteinization, demineralization, and decolorization processes. Chitin was converted to chitosan by the deacetylation process. The characteristics of isolated chitosan were compared to the standard chitosan. Both of those chitosans were characterized by using Fourier Transform Infrared (FTIR) Differential Scanning Calorimeter (DSC), and Scanning Electron Microscopy (SEM). The yields of chitin and chitosan obtained were 19.80 and 72.72%, respectively. The degree of deacetylation of chitosan was determined by using FTIR spectroscopy. The degrees of deacetylation of isolated and standard chitosan were 55.34 and 59.22%, respectively. The exothermic temperature peak of isolated chitosan was higher than standard chitosan. The isolation and standard of chitosan respectively had temperature peak values of 307.65 and 295.50oC. Based on SEM images, a smooth and homogeneous structure was found on the surface of the isolated chitosan and the amorphous sphere structure was observed in the standard chitosan. For biomedical purposes, the chitosan isolated from banana shrimp shells could be used as a material for nano chitosan synthesis.
