UV-C 조사가 국내에 유통되고 있는 수입 건어포류의 저장 중 미생물학적 변화와 품질에 미치는 영향을 연구하였다. UV-C 조사량은 5, 10, 으로 처리하여 대조구와 비교하였다. 조사시간은 5분 33초, 11분 6초, 22분 12초를 사용하였다. UV-C 조사에 의한 건어포류에 존재하는 오염된 미생물의 감소는 처리에서, 쥐포는 호기성 세균과 효모 및 곰팡이에서 각각 0.82, 1.23 log CFU/g, 문어포는 각각 1.20, 1.01 lo

The effect of UV-C irradiation on microbial growth and the quality of imported dried filefish and octopus during storage was examined. Samples of imported dried filefish and octopus were irradiated at 0, 5, 10 and and stored for 3 months at or for 6 days at . Exposure times of 5 min 33 sec, 11 min 6 sec, and 22 min 12 sec were used. UV-C treatment of the imported dried filefish and octopus decreased the populations of aerobic bacteria, yeasts and molds in proportion to radiation dose. Compared to the control, total aerobic bacteria, and yeast and mold populations were significantly lower (1-2 log CFU/g) with UV-C treatment of . UV-C irradiation caused negligible changes in the Hunter color L, a and b values. These results indicate that UV-C irradiation could be useful in inhibiting microbial growth on imported dried fish without impairing quality during storage.
