Abstract

Paprika is a major export of Korea, but biosafety is important if exports are to grow. To date, few paprika biosafety data are available. We evaluated microbiological contamination of paprika, and determined bacterial levels with respect to storage temperature. Mean counts of total aerobic bacteria were $2.3{\pm}0.3\;log_{10}\;CFU/g$, but coliforms were not isolated. Staphylococcus aureus, Salmonella spp., Listeria spp., and Escherichia coli O157 were also not detected. When bacterial contamination of paprika stored at room temperature or $4^{\circ}C$ for 20 days was evaluated, the numbers of total aerobic bacteria peaked at 14-16 days at room temperature (4 times more than those of $4^{\circ}C$). However, aerobic bacteria grew slowly at $4^{\circ}C$. Coliforms were also detected twice at room temperature, but not upon storage at $4^{\circ}C$. The results indicate that the paprika exported from Korea is relatively biosafe. However, food hygiene issues must be addressed to reduce contamination during storage and distribution.

파프리카(Capsicum annuum var. angulosum)는 우리나라의 대표적인 수출농산물로서 지속적인 수출확대를 위해서는 안전성 확보가 중요하다. 지금까지 수출과채류의 생물학적 위해요소에 대한 연구는 많이 이루어 지지 않았다. 본 연구는 우리나라의 대표적인 수출 농산물인 파프리카를 대상으로 미생물오염실태를 모니터링하고, 보관온도에 따른 세균오염도 변화를 분석하였다. 파프리카의 평균 총호 기성균 수는 $2.3{\pm}0.3$ log CFU/g이었으며, 대장균군은 발견되지 않았다. 파프리카에서는 황색포도상구균이 발견되지 않았으며, 또한 Salmonella spp., Listeria spp. 및 E. coli O157:H7도 검출되지 않았다. 파프리카를 상온 및 $4^{\circ}C$에 각각 보관후 20일동안 세균 오염도를 측정한 결과, 상온에 보관시 총호기성균 수는 구입 14~16일에 가장 많이 증가하 였으나(4배 이상), $4^{\circ}C$에 보관시에는 세균 수 증가가 완만하였다. 대장균군은 상온에서 2회 검출되었으나, $4^{\circ}C$에서는 검출되지 않았다. 이상의 결과로 보아, 수출용 파프리카는 생물학적으로 안전하였으나, 상온에 장기간 보관시 유해미생물의 오염 가능성이 있으므로 유통과정중 철저한 위생관리가 요구된다.
