• Changes of Properties of Chitosan Film by ⁶⁰Co γ-ray Irradiation

抄録

Due to a remarkable deterioration of material properties when chitosan film is dry-heat-sterilized,chitosan film is conventionally sterilized with the gas sterilization method.<br/> However, there is a potential risk of adverse effects of gas residue on a living body system. In this study, the film was sterilized under ⁶⁰Co γ-ray irradiation, and changes in properties were investigated.<br/> The main conclusions were as follows:<br/> 1.The tensile strength of chitosan film D70(Deacetyl 70%)with a lower level of deacetyl degree markedly decreased. On the other hand, films D85 (Deacetyl 85%), and D99(Deacetyl 99%)did not show any reduction in tensile strengths.<br/> 2. The tensile elongation of all films after the ⁶⁰Co γ-ray irradiation decreased. Among them,the film(Deacetyl 70%)showed the largest reduction in tensile elongation.<br/> 3. It was also observed that the ⁶⁰Co γ-ray irradiation caused film discoloration of turning yellowish.<br/> 4. The molucules of all chitosans after the ⁶⁰Co γ-ray irradiation decreased.<br/>
