Abstract

There have been contradictory reports concerning the role of garlic on kimchi fermentation; therefore, in this study, the stimulatory effect of garlic on the fermentation of kimchi was reappraised. In this study, fermentation of kimchi prepared using spring Chinese cabbage was stimulated by the addition of garlic, but kimchi prepared using autumn Chinese cabbage was not. In addition, the results of this study revealed that the fermentation of kimchi prepared using spring Chinese cabbage was found to be stimulated by glucose, yeast extract, peptone, and secondary ingredients of kimchi, but the fermentation of kimchi prepared using autumn Chinese cabbage was not stimulated by these ingredients. Taken together, these results indicate that general nutrients in garlic stimulate the fermentation of kimchi by compensating for nutrients that are not found in spring Chinese cabbages. However, these findings do not indicate that certain specific substance(s) in garlic stimulate kimchi fermentation.

김치를 제조할 때 마늘이 김치의 발효를 촉진시킬 때도 있지만 영향을 미치지 못할 때도 있었다. 배추 자체만으로도 발효가 충분히 일어나는 가을 배추김치에는 마늘을 첨가하여도 발효촉진 작용이 나타나지 않았지만, 자체만으로는 발효력이 약한 봄 배추김치에는 마늘을 첨가했을 때 발효촉진 현상이 관찰되었다. 봄 배추를 사용하여 만든 김치에 포도당, yeast extract와 peptone, 김치 부재료를 각각 따로 첨가했을 때에도 마늘을 첨가했을 때와 같은 촉진현상이 관찰되었으나, 가을 배추김치에서는 촉진현상이 거의 나타나지 않았다. 따라서 마늘이 김치의 발효를 촉진하는 현상은 마늘 특유의 고유한 성분에 의한 촉진작용이 아니고 배추의 영양소 구성성분 특성에 따라 나타나는 현상으로 해석되었다. 즉, 마늘의 첨가를 통해 공급되는 당이나 영양성분이 봄 배추의 부족한 영양을 보충해 줌으로써 나타나는 일반적인 현상으로 판단되었다.
