초록

본 연구는 여러 가지 기능성을 갖는 대나무추출액을 첨가한약주를 개발하기 위하여 대나무 알코올추출액을 사용하였으며 풍미를 향상시키기 위하여 생강과 배를 첨가하여 약주를 제조한 후 품질특성과 관능검사를 실시하였고 이들의 항산화 활성과 아질산염 소거능 등 기능성을 조사하였다. 대나무 알코올추출액 첨가한 약주의 pH는 대조구에 비하여 낮았으나 총산과 당도는 높았다. 알코올 함량은 대조구에 비하여대나무 알코올추출액을 첨가한 약주가 약간 높았다. 색도인L값은 대나무 알코올추출액을 첨가한 약주가 대조구에 비해낮았고 b값과 갈변도는 높았다. 약주의 성분 중 유기산은citric acid, malic acid, succinic acid, lactic acid, aceticacid 등이 검출되었으며 모든 처리구에서 lactic acid가 가장 많이 함유되어 있고 유리당은 sorbitol, glucose 및 fructose가검출되었고 glucose 함량이 가장 높았다. 총 폴리페놀 함량은 대조구가 약간 높았다. 항산화 활성은 대나무 알코올추출액을 첨가하지 않은 대조구가 5.8%로 가장 낮았으나 대나무 알코올추출액을 첨가한 약주에서는 23.8~31.0% 로 높게 나타났다. 아질산염 소거능은 pH 1.2와 3.0에서는모든 처리가 97.5% 이상의 활성을 보인 반면 pH 6.0에서는대나무추출액을 첨가하여 발효한 약주에서 15.2~36.4%의활성을 나타내었다. 관능평가 결과 대나무 알코올추출액+ 생강, 대나무 알코올추출액+생강+배 첨가 약주가 향, 맛및 전반적인 기호도에 있어서 유의적으로 높았다.

This study was carried out to develop Yakju, a new kind of Korean traditional rice wine added with bamboo ethanol extract and characterized by containing various health benefits. The wine with bamboo ethanol extract was fermented by adding ginger and pear to improve flavor and quality. Several quality characteristics and physiological functionalities of Yakju were investigated. When bamboo ethanol extract was added to Yakju, the pH level decreased compared to that of the control. However, total acidity and soluble solid levels were higher than those of the control. The alcohol content of Yakju added with bamboo ethanol extract was slightly higher than that of the control. In examining the colors of Yakju containing bamboo ethanol extract, L value was lower than that of the control, whereas b value and brownness were higher. Various organic acids such as citric acid, malic acid, succinic acid, lactic acid, and acetic acid were determined, and the main organic acid among them was lactic acid. Various free sugars such as sorbitol, glucose, and fructose were detected and glucose was the most abundant. Total polyphenol content of Yakju added with bamboo ethanol extract was lower than that of the control. Further, electron-donating ability ranged from 23.8～40.0%, which was higher than that of the control. Nitrite scavenging ability of Yakju added with bamboo ethanol extract ranged from 15.2～36.4%, which was higher than that of the control at pH 6.0. Sensory evaluation of Yakju showed that bamboo ethanol extract+ginger as well as bamboo ethanol extract+ginger+pear treatment significantly increased flavor, taste, and overall acceptance compared to the others.
