Abstract
This study aimed to evaluate the extract of chitosan obtained from pink
shrimp (Parapenaeus longirostris) shell wastes in Balıkesir, the Marmara
Sea in Turkey, and to characterize its quality. The physicochemical
properties of biopolymer chitosan such as moisture content, solubility,
degree of deacetylation (DD), molecular weight (MW), particle size, bulk
density, pH, water-binding capacity (WBC), fat-binding capacity (FBC),
and color attributes were examined. The obtained chitosan was
characterized by Fourier transform infrared spektrofotometer (FT-IR),
Dynamic light scattering (DLS), and Thermogravimetric measurements
(TG/DTA/DTG). Results indicated that the yield and moisture content of
chitosan was 18.82% and 3.62%, respectively. DD was 81.50% while
solubility was 86.79%. MW of chitosan was found to be 310 kDa. The
presence of the amino group was confirmed from the FT-IR spectra of the
synthesized chitosan. Thermogravimetric measurements showed that
chitosan had low thermal stability. SEM analysis revealed that the surface
morphologies of chitosan consisted of relatively smooth surface and
nanofiber structures. Based on the physicochemical characteristics
obtained in the present study, pink shrimp could be a potential source to
produce high-quality chitosan for industrial applications.
