Abstract

The replacement effects of cheese far salted and fermented fish on growth of lactic acid bacteria, fermentation velocity and sensory characteristics of Kimchi were investigated. In both control and cheese Kimchi, the total viable cell count of lactic acid bacteria was increased rapidly during the initial 2 days of fermentation. From 3 days after preparation, Kimchi added with cheese showed higher number of lactic acid bacteria than control Kimchi. The pH of Kimchi decreased rapidly after a small increase at the first day of fermentation, reaching 4.18-4.33 at the third day of fermentation, and the pH was slightly lower in Kimchi added with cheese than in control. Proximate analysis of Kimchi added with cheese was slightly higher in moisture and lower in crude protein and fat than control Kimchi. Sensory evaluation of the Kimchi fermented for 3 days showed that the Kimchi added with 3 or 5% of cheese had higher scores of appearance, flavor and overall taste than the control Kimchi.

본 연구는 배추김치 제조시 김치의 단백질원인 젓갈 대신 치즈를 첨가하였을 때 김치의 발효적, 이화학적 및 관능적 품질 특성을 조사하였다. 젓갈이 첨가된 대조구와 치즈가 첨가된 김치 모두 담근 후 2일까지 빠른 속도로 미생물이 증식되었으나, 담근 후 3일부터는 치즈 첨가 김치가 대조군 김치에 비하여 높은 생균수를 보였으며, 치즈 첨가량이 많을수록 더욱 더 높았다 pH는 대조구와 치즈 첨가 김치 모두 담근 후 하루동안 일시적으로 약간 상승하다가 2일째부터 급격히 저하되어 3일째에는 pH4.33-4.18로 가장 맛있다고 일반적으로 평가되는 김치의 pH 범위를 보였으며, 치즈 첨가량이 많을수록 pH가 다소 낮은 경향이었다. 발효속도는 대체로 치즈 첨가량이 많을수록 빨랐으며 특히 발효 3일 이후에는 7% 치즈 첨가군이 발효속도가 가장 빨랐다. 일반성분을 분석한 결과 치즈를 첨가한 시험구에서는 수분이 대조구보다 다소 낮게 나타났고 조단백질과 조지방이 다소 높은 경향을 보였다. 담근 후 3일 된 김치의 관능검사를 실시한 결과 젓갈을 넣은 대조구 김치보다 치즈를 3%, 5% 첨가한 김치가 외관, 향미, 질감, 맛 등 관능에서 대체적으로 좋은 점수를 받았다
