Abstract
This study was conducted to evaluate the possible subacute toxicity of gamma-irradiated dried bibimbap. The dried bibimbap was irradiated at the dose of 30 kGy at room temperature. For the animal study, the male and female ICR mice (8 mice per group) had the diet with AIN39G as control and dried bibimbap 30 kGy irradiated and non-irradiated for three months. During the experimental period, the group with 30 kGy irradiated bibimbap did not show any changes in appearance, behavior, mortality, body weight, organ weight, and food consumption compared to the control. Also, all of the biochemical parameters were observed in the normal ranges. In histopathological examination including hematological and serum biochemical analyses, there were no significant differences among the control and 30 kGy irradiated dried bibimbap groups. These results indicate that irradiation of bibimbap up to 30 kGy did not cause any toxic effects and could be applied for the development of safe ready-to-cook food.
