김치 제조시 위생적 품질 개선을 위하여 ethanol과 천연항균물질인 polylysine의 복합 첨가를 검토하였다. Ethanol 농도를 0.3, 0.6 및 0.9%로 첨가하여 김치를 제조한 후 1에 저장하면서 3일 간격으로 총균수, 대장균군, 젖산균, 곰팡이 및 효모 등을 비교 측정한 결과, ethanol의 첨가는 대장균군과 젖산균의 생육 억제에 있어 보다 효과적인 것으로 나타났으며, ethanol 농도 0.6% 첨가시부터 미생물 생육 억제 효
Addition of ethanol and/or polylysine to kimchi was investigated to improve its microbial hygienic quality and to extend shelf-life. Ethanol was added to kimchi with several concentrations(0.3％, 0.6％, 0.9％) and stored at 10. Addition of 0.6％ and 0.9％ ethanol showed apparent inhibitory effect on growth of microorganism, but any distinct difference was not found between those concentrations. Addition of ethanol was more effective on growth inhibition of coliform and lactic acid bacteria than others. Addition of 0.6％ and 0.9％ ethanol retarded apparently pH decrease and acidity increase. Although addition of 0.6％ ethanol in combination with 0.12％ polylysine showed good retardation of pH decrease and acidity increase, overall organoleptic quality was not good because of off-flavor and taste. Also, addition of 0.6％ ethanol showed good overall organoleptic quality.
