Abstract EN
Keeping the importance of chitin and chitosan in mind, an attempt has been made on the extraction of chitin and chitosan from local shrimp waste using a chemical method.
The influence of using ionizing radiation before chemical treatment on the time needed for deproteination and demineralization process was investigated.
Deacetylation process was conducted by the conventional thermal heating.
The degree of deacetylation (DDA%) was determined by potentiometric titeration method.
The intrinsic viscosity and the weight average molecular weight (MW) were de termined by viscometric method.
Comparison between physicochemical properties of chitin and chitosan extracted from both non irradiated and irradiated shrimp waste was studied using Fourier Transform Infrared spectroscopy (FTIR), X–ray diffraction analysis (XRD) and thermogravimetric analysis (TGA).
The results showed that irradiation causes the reduction of time of deproteination, demineralization and deacetylation processes.
Also, chitosan prepared from irradiated sample has higher solubility, DDA% and lower molecular weight.
