Summary
Gamma irradiation of shrimp chitosan (10kGy & 20kGy) enhances its stability and structural properties. This modified chitosan, with smaller polymer size and compacted structure, is suitable for food industry applications.
Area of Science:
- Materials Science
- Biochemistry
- Food Science
Background:
- Chitosan, a biopolymer derived from shrimp waste, possesses valuable properties but can be modified for enhanced functionality.
- Gamma (γ) irradiation is a method used to alter the physical and chemical characteristics of biopolymers.
Purpose of the Study:
- To investigate the morphological, elemental, and functional group changes in chitosan after gamma irradiation.
- To assess the impact of 10kGy and 20kGy gamma irradiation on shrimp-derived chitosan.
Main Methods:
- Fourier Transform Infrared (FTIR) spectroscopy for functional group analysis.
- X-ray Diffraction (XRD) for structural characterization.
- Thermogravimetry/Differential Thermal Analysis (TG/DTA) for thermal stability assessment.
Main Results:
- Gamma-irradiated chitosan exhibited a smaller polymer size, reduced pore size, and a more compacted structure compared to non-irradiated samples.
- FTIR analysis revealed the presence of active alkyl and hydroxyl groups in irradiated chitosan.
- TG/DTA indicated increased thermal stability in the gamma-irradiated chitosan.
Conclusions:
- Gamma irradiation (10kGy & 20kGy) significantly modifies the structure and enhances the stability of shrimp-derived chitosan.
- The improved properties make irradiated chitosan a promising candidate for diverse applications within the food industry.
