Abstract

This study evaluated the microbial population (total aerobic count, fungi) and organoleptic quality of freeze-dried bibimbap sterilized by gamma irradiation to develop the space food. An irradiation dose above 30 kGy was needed to sterilize the freeze-dried bibimbap, while organoleptic quality of the sample was significantly decreased by irradiation (p<0.05). However, it was observed that scores on overall acceptance of rehydrated bibimbap after irradiation were the highest, when vitamin C and paprika extract were added at 0.1%, respectively. Therefore, it was considered that the freeze-dried bibimbap could be developed as a space food, which meet microbial requirements and organoleptic quality through addition of vitamin C 0.1% and paprika extract 0.1% before gamma irradiation at 30 kGy.
