Abstract

This study was conducted to investigate the effect of addition methods of green tea on the fermentation characteristics of kimchi. Kimchis were prepared to 3 methods such as Chinese cabbage soaked in brine containing 1％ of green tea extracts(Ⅰ), salted the cabbage soaked in water containing 1％ of green tea extracts(II), salted the cabbage mixed with seasonings containing 1％ of green tea extracts(Ⅲ), and fermented at l0$\^{C}$. pH of Ⅰ∼Ⅲ kimchis were higher than that of control kimchi during fermentation and its acidity showed the same tendency. Total microbe(5.40∼8.38 log cfu/mL) and the number of lactic acid bacteria(4.99∼8.07 log cfu/mL) in Ⅰ∼Ⅲ kimchis were lower than those of control kimchi(6.16∼9.29 and 4.59∼8.42 log cfu/mL). Lightness of kimchi tissue showed the order of Ⅰ＜II＜control＜Ⅲ. Sour taste and fishy taste of Ⅰ∼Ⅲ kimchis were lower than that of control kimchi. Overall quality was best in II estimated by sensory evaluation and fermentation characteristics.

김치제조시 녹차의 첨가방법이 발효특성과 관능적 품질에 미치는 영향을 조사하기 위하여 1%의 녹차추출물를 함유하는 소금물로 절인 후 담근 김치(I), 절임배추를 1% 녹차추출 물에 일정시간 담금후 제조한 김치(II), 녹차 1%를 양념과 혼합하여 담근 김치(III)의 3가지 방법으로 김치를 제조한 후 1$0^{\circ}C$에서 숙성시키면서 pH, 산도, 균수, 색상 및 관능적 품질을 조사하였다. 대조구의 pH는 숙성중 I~III의 경우보다 낮아 녹차처리구가 숙성이 지연되었다. 산도의 경우도 pH와 역으로 pH의 결과와 일치하였다. 그러나 녹차처리방법에 따른 큰 차이는 보이지 않았다. 대조구의 총균수와 젖산균수는 각각 6.16~9.29 및 4.59~8.42 log cfu/mL로I~III의 5.40~8.38 및 4.99~8.07 log cfu/mL보다 높았다. 김치조직의 L＊값은 I< II
