Abstract

The effects of the ratio of 45% alcohol and Maesil(Prumus mume) (1:1, 1:2, 1:3, w/v) on quality changes of Maesil liqueur during leaching and ripening for 5 months were examined. Total acidity increased with an increase ratio of Maesil and leaching and ripening periods. The pH increased as increase ratio of alcohol. The color of liqueur became dark as an increase ratio of Maesil and leaching and ripening periods. The contents of alcohol after leaching and ripening for 2 months were 24.3%(1:1), 32.2%(1:2), and 36.0%(1:3), respectively and decreased as an increase the ratio of Maesil. The contents of reducing sugar and polyphenol in the liqueur increased with an increase ratio of Maesil and leaching and ripening periods. The major components of free sugar in the liqueur were fructose, glucose, sucrose and maltose but sucrose and maltose did not detect regardless the ratio of Maesil after leaching and ripening for 2 months. The major components of organic acid in the liqueur were citric, lactic, malic, and acetic acids. The total amount of organic acid increased as an increase the ratio of Maesil but the changes of individual organic acid in the liqueur contained different ratio of Maesil showed the different tendency each other.

매실과 45% 알코올의 담금비 1:1, 1:2, 1:3 (w/v)의 비율로 조절하여 $20^{\circ}C$에서 5개월간 숙성시키면서 매실리큐르의 품질을 조사하였다. 산도는 매실의 담금 비율이 증가할수록 숙성기간이 경과할수록 증가하였다. pH는 알코올 첨가량이 증가할수록 pH는 높았다. 색도는 매실의 담금비가 증가할수록, 숙성 기간이 길어질수록 점차 짙은 색도을 나타내었다. 알코올 농도는 매실의 담금 비율이 증가할수록 감소하였으며 숙성 2개월째는 각각 24.3(1:1), 32.2(1:2), 36.0%(1:3)이었으나 그 후 담금비에 따른 뚜렷한 변화는 관찰할 수 없었다. 숙성 기간 중 환원당과 polyphenol 함량은 매실의 담금비가 증가함에 따라 증가하였다. 숙성 1개월까지 담금액 중에는 fructose, glucose, sucrose 및 maltose로 4종류의 당이 존재하였으나, 숙성 2개월 이후 sucrose와 maltose는 각 처리구 공히 검출되지 않았다. 담금액에서 매실 첨가량에 관계없이 citric, malic, succinic, lactic, acetic acid가 검출되었으며, 매실의 담금비가 증가할수록 유기산 전체 함량은 증가하였으며, 담금 비율에 따른 숙성 기간 중 유기산 함량의 변화는 서로 다른 경향을 나타내었다.
