매실의 첨가 형태와 첨가량을 달리하여 제조한 김치를 에서 25일간 저장하면서 김치의 발효 및 품질특성을 조사하였다. 대조구의 pH는 발효 기간이 경과 할수록 급격히 감소하였으나, 매실 첨가구는 서서히 감소하였다. 산도의 변화도 pH와 유사한 경향을 나타내었다. 매실 첨가구는 발효 초기에 미생물의 성장이 다소 지연되었으나, 발효 말기에는 CFU/mL의 균수를 나타내어 대조구와 유사하였다. 김치의 색도는 담금 직후 매실 첨가구는 대조구에 비해 L,

The fermentation and quality characteristics of kimchi prepared using various types of maesil, including freshly sliced maesil (FSM), freshly ground maesil (FGM),and dried maesil powder (MP), were investigated during 25-day fermentation at 10C. The pH value decreased rapidly in the control fermentation but only slowly in maesil-supplemented kimchi. Titratable acidity values changed in the same manner. The addition of maesil significantly inhibited the growth of total aerobes, and lactic acid bacteria during fermentation over 10 days. The color (L, a, and b values) of kimchi did not differ between control and maesil-supplemented kimchi samples regardless of maesil type or concentration. Kimchi hardness did not initially differ among the various samples but decreased during fermentation. However, the hardness of maesil-supplemented kimchi was higher than that of control samples. Thus, kimchi supplemented with either 6% (w/w) MP or 6% (w/w) FGM maintained optimal hardness during fermentation. The antioxidant activity of kimchi was increased in a dose-dependent manner by addition of maesil. Kimchi supplemented with 6% (w/w) FGM showed the highest antioxidant activity. The sensory qualities (taste, flavor, color, and overall acceptability) of FSM-supplemented kimchi were better than those of control samples.
