This study was investigated the potential toxicity of gamma-irradiated chocolate ice cream for its future use in space. Chocolate ice cream was irradiated at a dose of 30 kGy at a temperature of -20oC. For the animal study, AIN-93G was used as a control diet and irradiated and non-irradiated chocolate ice cream diets were administered to male and female ICR mice (ten mice per group) for three months. During the experimental period, the group fed irradiated chocolate ice cream did not show any changes in appearance, behavior, mortality, body weight, organ weight, or food consumption compared to the control. Also, all biochemical parameters, including hematology profiles, erythrocyte counts, and serum biochemical values were in normal ranges. In histopathological examinations of liver and kidney tissues, there were no significant differences between the control group and the group fed irradiated chocolate ice cream. These results indicate that chocolate ice cream irradiated at 30 kGy did not cause any toxic effects and could be applied for the development of safe and hygienic space food.
