Abstract

This study investigated the development of health promoting high quality Mumalangi Kimchi. Angelica gigas Nakai leaves (AGL) were extracted with water and 70% ethanol, and the extracts tested for their electron donating ability (EDA), nitrite scavenging ability (NSA) and inhibitory effects on MDA and A549 cells. The EDA in 100-1,000 ppm water extracts from AGL ranged from 40 to 80%, but that of the ethanol extracts ranged from 37 to 81%. The NSA increased with increasing AGLconcentration in the extracts and decreasing pH. The NSA of the 1,000 ppm water and ethanol extracts from AGL were 29 and 35%, respectively, at pH 1.2. The inhibition ratios of the water and ethanol extracts from AGL on MDA cell growth were 35 and 32%, while those on A549 cell growth were 27 and 23%, respectively, at 1,000 ppm. After sun drying radishes for 15 hours, for the preparation of Mumalangi, the water contents were higher in summer radishes (39.5%) than fall radishes (32.6%) the color of summer radish also changed to brown. During storage of Mumalangi Kimchi, with the addition of 1-3% AGL, at 20?for 4 weeks, the yeast growth was inhibited. The shelf-life of Mumalangi Kimchi was extended by the addition of AGL. In the sensory evaluation of Mumalangi Kimchi, that with the addition 2% AGL had the highest scores for color, flavor, taste, texture, after taste and overall acceptability. Mumalangi Kimchi with the addition of 2% AGL had significant high scores for both taste and overall acceptability (p.0.05).

본 연구는 기능성을 가진 무말랭이 김치를 개발하기 위하여 당귀잎을 물과 70% 에탄올로 추출하여 추출물의 전자공여능, 아질산염 소거능 및 항암활성을 검토하고 당귀잎을 0-3% 첨가한 무말랭이 김치의 품질특성을 조사하였다. 당귀잎 추출물의 전자공여능은 물 및 에탄올 추출물 모두 추출물의 농도가 증가함에 따라 전자공여능도 증가하였으며 100${\sim}$1,000 ppm에서 물 추출물은 40-80%, 에탄올 추출물은 37-81%로 우수한 항산화능을 나타내었다. 추출물의 아질산염 소거능은 pH가 낮아짐에 따라 증가하여 pH 1.2에서 가장 높았고 동일 pH에서는 농도의존적으로 증가하였다. 당귀잎 추출물의 아질산염 소거능은 pH 1.2, 1,000 ppm 농도에서 물 및 에탄올 추출물은 각각 29%, 35%였다. 당귀잎의 물과 에탄올 추출물 1,000 ppm의 유방암세포(MDA cell)에 대한 증식 억제율은 각각 35%, 32%, 폐암세포(A549 cell)에 대한 증식 억제율은 각각 27%, 23%였다. 무말랭이 제조를 위하여 무를 햇볕에서 15시간 동안 자연건조 시켰을때 수분함량은 여름무(39.5 %)가 가을무(32.6%)에 비하여 높고, 여름무는 건조과정에서 갈변현상을 나타내었다. 당귀잎을 1-3% 첨가한 무말랭이 김치를 20$^{\circ}C$에서 4주간 저장하였을 때 당귀잎 첨가량이 많을수록 효모수가 낮았으며 당귀잎 첨가에 의하여 무말랭이 김치의 저장성이 향상되었다. 무말랭이 김치의 관능검사 결과, 맛, 색상, 물성, 향, 뒷맛, 종합적인 기호도에서 당귀잎 2% 첨가한 김치가 가장 높은 점수를 얻었다. 특히 맛과 종합적인 기호도는 당귀잎 2% 첨가구에서 유의적으로 높은 기호도를 나타었다(p<0.05).
