Abstract

The 21 Kimchi samples collected by a contest for the best Kimchi homemaker in Jeonju were analysed to find major microbial composition and the correlation between sensory scores and the microbial properties, which include total microbial numbers, dominant strain number, subdominant strain number, yeast strain numbers, and floral diversity. The most common microbial composition of the Kimchi samples was Leuconostoc mesenteroides as dominant strain, and Lactobacillus sakei as subdominant strain, the pattern of which was also observed in all three Kimchi samples with the highest sensory scores, but not in all three Kimchi samples with the lowest sensory scores. However none of the other examined properties showed any significant correlation to sensory scores. This result means that the taste of fermented Kimchi depends mainly on the composition of bacterial species and that of Leuconostoc mesenteroides as dominant strain and Lactobacillus sakei as subdominant strain is the best for good taste. Yeast strains were found in the range of $3.8{\sim}4.6log\;CFU/g$ from 8 Kimchi samples and all the strains were identified to be Saccharomyces servazzii. However, fungi were not detected from any of the Kimchi. samples.

전주지역에서 김장시기에 수거한 김치의 미생물 조성과 관능성적간의 상관성을 조사하여 다음의 결과를 얻었다. 김치는 21 표본 중 11 표본에서 L. mesenteroides가 $8.31{\sim}11.27log\;CFU/g$의 범위에서 지배균으로, 16 표본에서 L. sakei가 $7.97{\sim}10.57log\;CFU/g$의 범위에서 차지배균으로 나타났다. 김치의 관능성적은 총균수, 지배균수, 차지배균수, 균종수 등 계량적 특성에는 유의적 상관성이 없었다. 가장 맛이 좋은 김치 3종은 모두 지배균이 L. mesenteroides, 차지배균은 L. sakei인데 비해 가장 맛이 없는 김치 3종은 지배균에 L. sakei가 많아 김치의 맛은 주요 미생물의 균종의 조합과 관련이 있었다. 효모는 8표본에서 $3.80{\sim}4.6log\;CFU/g$의 범위로 검출되었으며 모두 Saccharomyces servazzii로 동정되었다. 곰팡이는 전혀 검출되지 않았다. 효모 균수와 김치의 관능성적은 유의적 상관성이 없었다.
