Abstract

The effects of combined treatment of aqueous $ClO_2$ and UV-C or electron beam irradiation on microbial growth and quality in chicon during storage at $4^{\circ}C$ were investigated. Samples were treated separately with 50 ppm of $ClO_2$, 5 kJ/$m^2$ of UV-C, 2, 5, 7, and 10 kGy of electron beam irradiation, as well as a combination of $ClO_2$ and UV-C or 2 kGy of electron beam irradiation. The populations of total aerobic bacteria as well as yeast and molds in the chicon samples were determined following each treatment. The populations of total aerobic bacteria in the chicon samples decreased by 1.49~2.92 log CFU/g following combined treatment of $ClO_2$ and UV-C irradiation compared to the control, whereas the populations of yeast and molds decreased by 1.63~1.78 log CFU/g. On the contrary, following combined treatment of $ClO_2$ and electron beam irradiation, the populations of total aerobic bacteria as well as yeast and molds in the chicon samples were undetectable during storage. Color measurements indicated that Hunter $L^*$, $a^*$, and $b^*$ values were not significantly different among the treatments during storage. These results suggest that combined treatment of $ClO_2$ and electron beam irradiation can be useful for improving microbiological safety in chicon during storage.

치콘의 미생물학적 안전성을 확보하기 위해 50 ppm 이산화염소수와 5 kJ/$m^2$ UV-C 및 2 kGy 전자빔 조사 병합처리에 따른 저장 중 미생물 수 및 품질 변화를 $4{\pm}1^{\circ}C$에서 11일 동안 저장하면서 측정하였다. 이산화염소수와 UV-C 병합처리 후 치콘의 총 호기성 세균 수는 대조구와 비교하여 1.49~2.92 log CFU/g, 효모 및 곰팡이는 1.63~1.78 log CFU/g의 감소를 보였다. 반면에, 이산화염소수와 2 kGy 전자빔 병합처리구의 경우 총 호기성 세균은 저장기간 동안 검출되지 않았으며, 효모 및 곰팡이 역시 11일 간의 저장기간 동안 나타나지 않았다. 이산화염소수와 전자빔의 병합처리는 대조구와 비교하여 치콘의 저장 중 Hunter 색도 값에 부정적 영향을 미치지 않았다. 관능검사에 있어서도 저장기간 동안 대조구와 비교 시 유의적인 차이가 없는 것으로 나타났다. 따라서 본 연구결과, 이산화염소수와 전자빔 조사의 병합처리가 치콘의 저장 중 오염될 수 있는 위해미생물의 감소와 외관적 품질유지에 효과적인 살균처리 기술이라고 판단된다.
