Abstract

In order to investigate the possible use of vegetable kimchi stuff as natural preservatives for kimchi, the methanol extracts of 15 kinds of vegetable kimchi stuff were solvent-fractionated and fractions were tested for antimicrobial activities against Leuconostoc mesenteroids, Pediococcus cerevisiae, Lactobacillus plantarum and Saccharomyces cerevisiae. The neutral fractions of the extracts of garlic and leek showed strong antimicrobial activities. The extract of leek showed particularly strong antimicrobial activities against Ped. cerevisiae and L. plantarum that were known to be main microorganism of fermentation and acidification of kimchi. The results suggest the possible use of the leek extract as natural preservatives for kimchi.

김치의 천연보존제로서의 이용가능성을 검토하기 위하여 15종의 식물성 김치재료를 MeOH로 추출, 용매분획하여 얻어진 산성구, 중성구 그리고 수용액구에 대해 김치 주발효미생물인 Leuconostoc mesenteroides, Pediococcus cerevisiae, Lactobacillus plantarum과 Saccharomyces cerevisiae를 대상으로 항미생물활성을 검색한 결과, 마늘과 부추추출물의 중성구에서 뚜렷한 항미생물활성을 나타냈다. 특히 부추추출물은 김치의 숙성 및 산패원인균으로 알려진 Ped. cerevisiae와 L. plantarum에 대해서 현저한 항미생물활성을 나타내, 김치의 천연보존제 및 산패억제제로서 부추추출물의 이용가능성이 시사되었다.
