Abstract

This study was performed in order to investigate the effect of Leuconostoc mesenteroides, Lactobacillus plantarum and salt fermented anchovy extracts on Kimchi sauce. The sauce was fermented more rapidly by addition of Leu. mesenteroids or salt fermented anchovy extracts on the early fermentation stage than the control, but it was fermented slowly on the late fermentation stage. When L. plantarum was added to the Kimchi on the early fermentation stage, the acidity of Kimchi didn't show a significant difference from the control, but acidity was remarkably increased on the late stage. Coliform group was disappeared when acidity of sauce was higher than 0.8% during fermentation. It was controlled by Leu. mesenteroides but not by L. plantarum. Total count and lactic acid bacterial count of the sauces with starter were $6.30{\times}10^6{\sim}1.0{\times}10^7\;CFU/mL$ and $1.04{\sim}2.04{\times}10^6\;CFU/mL$, respectively, but those of the control sauce were $10^6\;CFU/mL$ and $10^4\;CFU/mL$, respectively. Those count of the sauce with starter were higher than those of the control sauce on the later stage of fermentation. Organoleptic quality of the sauce with Leu. mesenteroides was superior to that with L. plantarum.

양념에 Leu. mesenteroides, Lac. plantarum의 젖산균과 멸치액젓 첨가가 김치 양념의 대장균군 제어, 숙성촉진여부 및 관능적 특성에 미치는 영향을 조사하였다. Leu. mesenteroides과 젓갈을 첨가한 경우 초기 숙성이 촉진되나 후기 산패는 완만하였으며 Lac. plantarum의 첨가시에는 초기 숙성에는 큰 차이가 없고 후기 산패가 현저하게 진행되었다. 대장균군은 산도 0.80% 이상에서 사별되었는데 Leu. mesenteroides의 경우가 숙성이 촉진되어 보다 신속히 사멸시켰다. 총균수와 젖산균수는 초기에 starter 첨가구는 $10^6\;CFU/mL$ 정도인데 반해서 starter를 첨가하지 않은 처리구에서 총균수는 $10^6\;CFU/mL$, 젖산균수가 $10^4\;CFU/mL$ 이었고 숙성 후에는 첨가군이 높은 수준을 유지하였다. 하지만 대체적으로 스타터의 첨가가 숙성 및 대장균에 크게 영향을 주지 못하는 경향으로 동일하게 나왔다. 관능적 특성에서는 Leu. mesenteroides 첨가구가 Lac. plantarum의 경우보다 우수하였다. 한편, 시판 겉절이 김치는 산도가 $0.09{\sim}0.18%$, $pH\;5.46{\sim}5.89$, 총균수 $2.2{\times}10^6{\sim}3.1{\times}10^7\;CFU/ml$, 젖산균수 $2.1{\times}10^4{\sim}6.6{\times}10^5\;CFU/ml$, 대장균군수 $1.8{\times}10^4{\sim}7.1{\times}10^5\;CFU/ml$, 염분 $1.89%{\sim}2.51%$으로 스타터 첨가 겉절이에 비해 pH와 염도를 제외한 품질 특성에서 전반적으로 낮은 값을 나타냈다.
