Abstract

To examine the difference in each ingredient between the yeast strain and two raspberry kinds (Rubus crataegifolius Bunge(RCB), Rubus coreanus Miquel(RCM)) in the making of raspberry wine, five active dry yeasts were selected. Regarding the RCM ethanol content, the raspberry wine fermented by Lalvin Wl5 was the highest, while those fermented by Prise de Mousse were the lowest. The pH of the RCM was $3.58\~3.63$, and Montrachet was the highest one of total acidity. In the case of nonflavonoid phenols, the RCM fermented by Montrachet was the highest one, and in the case of flavonoid phenol and total phenol, the RCM fermented by Epernay II was the highest. The content of organic acid in RCM were highest in the following order: citric acid > oxalic acid > malic acid, and tartaric acid was not detected at all. The average content of malic acid in RCM after malolactic fermentation was reduced by almost $65.5\%$, and the RCM fermented by Prise de Mousse, after malolactic fermentation, was $73.3\%$. This latter was the highest, while the RCM fermented by Epernay II was the lowest, at $59.1\%$.

복분자주 양조에 있어서 대표적인 활성 건조 효모 5종을 선정하여 효모 균주간의 특성 및 복분자 품종(RCM, RCB)간의 성분 차이를 알아보기 위한 연구 결과는 다음과 같다. 1. 고창 복분자(RCM)주의 에탄을 함량은 Lanvin Wl5 균주로 발효된 복분자주가 $15.3\%$로 가장 높았고, Prise de Mousse 균주로 발효된 복분자주가 $14.4\%$로 가장 낮았다. 2. RCM주의 pH는 $3.58\~3.63$으로 효모 균주에 따른 차이는 별로 없었고, RCB주의 pH는 3.98로 더 높았다. 3. RCM주의 총산은 Montrachet 균주로 발효된 복분자주가 1.46 g/100 mL로 제일 높았고, 휘발산은Pasteur champagne 균주로 발효된 것이 0.111 g/100 mL로 제일 높았다. 4. Nonflavonoid phenols는 RCM 주중의 Montrachet 균주로 발효된 것이 1,850 mg/L로 가장 높았고, flavonoid phenol과 total phenol은 Epernay II 균주로 발효된 RCM주가 2,820 mg/L, 4,600 mg/L로 가장 높았다. 5. RCM주의 유기산 함량은 구연산>수산>사과산 순으로 많았고, 주석산은 검출되지 않았다. 6. RCM주에 있어서 사과산의 평균 함량은 malo-lactic fermentation후에 거의 $65.5\%$ 감소하였으며, Prise de Mousse 균주로 발효된 RCM주의 ma-lolactic fermentation 후의 사과산의 감소율은 약 $73.3\%$로 가장 높았으며, Epernay II 균주로 발효된 RCM주의 malolactic fermentation 후의 사과산의 감소율은 $59.1\%$로 가장 낮았다.
