더덕 함량을 10, 15 및 20% (w/v)로 달리하여 50% (v/v) 주정에 담아 밀봉한 후 상온에서 180일간 침출시킨 다음 더덕 침출주의 이화학적 및 관능적 특성에 미치는 영향을 조사하였다. 더덕 함량을 달리하여 상온에서 180일간 침출시킨 결과 총당은 더덕 함량이 많을수록 많은 양의 총당이 용출되는 경향을 보이고 있었으며 맛을 결정하는 환원당도 총당과 유사한 경향을 보이고 있었다. 한편 더덕의 유효성분인 total polyphenol의

The physicochemical characteristics and sensory properties of Deodeok wine, formed by leaching of Deodeok at room temperature for 180 days, were investigated over the following range of Deodeok levels: 10, 15 and 20% (all w/v). The higher the level of Deodeok, the greater were the final values of total sugars, reducing sugars, total polyphenols, and crude saponins. The Hunter's b-value (yellowness) of Deodeok wine varied markedly with Deodeok levels, and yellowness was highest in Deodeok wine containing 20% (w/v) Deodeok. Non-volatile compounds, that form the basis of the liquor tax law, were 0.64, 1.38 and 2.11% (all w/v), respectively, at day 160. Of these values, that of 2.11% (w/v), the level of non-volatile compounds in Deodeok wine containing 20% (w/v) Deodeok, was in accord with the liquor tax law (that requires this figure to be 2.0%). Sensory evaluation showed that Deodeok wine containing 20% (w/v) Deodeok was superior to the other wines tested.
