The gamma irradiation has been used as a method of sterilization which is often needed for long-term storage of various dried-foods by preventing them from decomposition. In present study, we tested the sterilization effects of gamma irradiation on the egg yolk powder containing anti-canine parvovirus yolk antibody (IgY) which can be used for controling canine parvovirus infection. Egg yolk powder was gamma irradiated at various levels (0.08, 0.4, 2, 10 and 50 kGy), stored at 4℃ and 20℃ for 60 days, and measured on sterility and antibody titer. Counting of aerobic bacteria indicated that samples irradiated at 0.4, 2 and 10 kGy were 89-94, 93-99 and 100% sterilized, respectively compared to non- irradiated control. ELISA test showed that gamma irradiation at 2 kGy or less did not make significant influence on antibody titer, whereas irradiation at 10 kGy induced about 15% reduction of antibody titer. Neither bacterial count nor antibody titer was affected by storage temperature after gamma irradiation. Conclusively, the proper level of gamma irradiation was about 2 kGy to achieve maximum sterilization on egg yolk powder without diminishing antibody titer.
