Abstract

In this study, four Korean black raspberry wines were developed from different regions in Korea; Gochang (G), Heongsung (H), Jeongup (J), and Sungchang (S). Their flavor profiles were determined using a combination of volatile analysis and sensory evaluation. From the volatile analysis of the developed wines, 8 acids, 17 alcohols, 12 esters, 9 terpenes, 3 aldehydes and ketones, and 4 miscellaneous compounds were identified. Preferences of appearance, aroma, full-body, and overall acceptability in the developed wines were determined using 9-point hedonic scale by 43 panelists, compared with one commercial black raspberry wine (Sunw). The sweetness, sourness, astringency levels were also evaluated using 9-point just-about-right (JAR) scale. The mean overall acceptability score of Sunw (5.58) was the highest among the tested wines, followed by G (4.81), S (4.44), H (4.41), and J (4.13) (p<0.05). Sweetness levels in the developed wines were overall lower than JAR level, while sourness and astringency levels were overall higher than JAR level.

국내 주요 복분자 산지인 고창, 정읍, 횡성, 순창산 복분자로 복분자주를 제조하여 제조 복분자주의 휘발성 향기성분 분석과 기호도 조사를 통해 산지별 차이를 파악하였다. 복분자주의 주요 향기성분으로 phenylethyl alcohol, isoamyl alcohol, diethyl succinate, isobutyl alcohol, acetic acid, octanoic acid, benzoic acid, $\alpha$-terpineol, myrtenol, pcymene-8-ol이 동정되었고 특히 적포도주에 비해 terpene류가 많이 검출되어 복분자주의 odor-active compounds를 분석하기 위해 gas-chromatography-olfactometry를 포함한 다양한 향기성분 분석 연구가 필요한 것으로 보인다. Ester류는 횡성산과 정읍산 복분자주에서 많이 검출되었고 alcohol과 acid류도 횡성산에서 가장 많은 농도를 나타내었다. Terpene류는 정읍산에서 가장 높게 나타났다. 차후 이들 시료에 대한 묘사분석을 통해 향기성분과의 상관관계 분석이 필요하리라 여겨진다. 전반적인 기호도에서는 제조복분자주에서 고창, 순창, 횡성, 정읍순으로 나타났고 특히 횡성과 정읍 시료의 경우 단맛은 약하고 신맛은 너무 강한 것으로 나타나 당산비 조절이 필요한 것으로 여겨진다.
