Abstract

The composition of two Bokbunja (Rubus coreanus Miquel) wines (one without mushroom extracts (wine A) and the other is with the extracts (wine B)) has been investigated to improve the quality of Bokbunja wine. The content of solid particle, acidity, crude ash, crude protein of the wine A were 10.5%, 1.36%, 0.45% and 0.05% and those of wine B were 7.4%, 0.54%, 0.31%, and 0.22%, respectively. Crude fat and crude fiber were not detected in both samples. To verify the flavor quality of Bokbunja wine, the volatile components from ethylether extracts of two wines were analyzed using GC/FID and GC/MS. A total number of 12 volatile flavor compounds (6 alcohols, 3 ketones, 1 acid, 1 ester and 1 anhydride) were identified in the two Rubus wines. The major volatile compounds of the wines were 2,3-butanediol, 2,5-furanedione, phenylethyl alcohol, and butanedioic acid and they might affect the major role in the unique flavor of Bokbunja wines.

복분자주의 품질 향상에 도움이 되고자 국내에서 생산되는 복분자주 (시료 A)와 버섯 추출물 첨가 복분자주 (시료 B)의 일반성분 분석과 향기성분 분석을 수행하였다. 일반 성분분석의 결과, 복분자주 시료 A와 복분자주 시료 B 중의 용해성 고형분은 10.5%, 7.4%로 분석되었고, 산도는 1.36%, 0.54%로 측정되었다. 수분은 83.27%, 87.62% 조회분은 0.45%, 0.31% 조 단백질은 0.05%, 0.22%였으며 조지방과 조섬유는 검출되지 않았다. 향기 성분의 확인을 위하여 두 시료의 향기 성분을 ethylether로 추출하고 methanol에 녹여 GC/FID와 GC/MS로 분석, 동정하였다. 두 시료에서 모두 12종의 성분이 동정되었으며, 이 중에서 alcohol류가 6종, ketone류가 3종, ester/acid/anhydride류가 각각 1종으로 나타났다. 주요한 휘발성 성분으로는 2,3-butanediol, 2,5-furanedione, phenylethyl alcohol, butanedioic acid 등이 있었으며, 이들 성분이 복분자주의 전체적 향미에 영향을 미치는 것으로 판단할 수 있다.
