초록

최근 건강에 대한 관심이 높아지면서 과일 가공제품의 소비가 급증하고 있다. 포도는 페놀화합물의 주요 급원의 하나로 포도주스는 항산화, 항염증, 항혈소판 작용 등의 기능을 가지는 다수의 플라보노이드를 포함하고 있다. 일반적으로 캠벨 포도는 농가에서 주스나 와인으로 가장 널리 가공되고 있으나 다양한 포도 품종을 이용하여 브렌딩한 포도주스에 대한 연구는 거의 전무한 실정이다. 본 연구에서는 캠벨과 타품종 포도주스를 종류 및 비율을 달리하여 브렌딩 한 후 물리화학적 특성, 관능적 특성, 기능적 특성에 대하여 평가하였다. 품종과 브렌딩 비율에 따라 물리화학적 특성 및 기능적 특성에서 유의적인 차이를 확인할 수 있었으며 캠벨 주스의 비율이 증가함에 따라 total phenol, total anthocyanin, total flavonoid 함량과 radical scavenging activity가 증가하였으나, 모든 포도 품종을 동일비율로 혼합하여 만든 포도주스는 기능성이 가장 낮은 특징을 보였다. 특히 캠벨 포도주스와 스투벤 포도주스를 브렌딩 한 경우 기능적 특성이 가장 우수하였으며 캠벨 포도주스와 거봉 포도주스를 동일 비율로 브렌딩 한 주스의 관능적 특성이 가장 우수하였다. 따라서 캠벨과 타품종 포도주스의 브렌딩을 통하여 기존의 캠벨 포도주스 제품의 품질을 향상시킬 수 있을 것으로 생각한다.

Campbell juice (25%, 50%, 70% and 90%) was blended with different concentrations (10%, 25%, 30% and 50%) of juice from a range of grape varieties including Kyoho, Steuben and MBA. The concentrations of Campbell and the grape variety juices influenced the physicochemical characteristics of the blended grape juice. As the concentration of Campbell juice increased, there was an increase in the mean content of bioactive compounds including total phenolics, anthocyanin and flavonoids, and the radical scavenging activity increased. The treatment containing 25% juice from the various grape varieties had the lowest level of bioactive compounds. A sensory evaluation showed there was no significant difference among the blended juice samples in terms of aroma. The sample comprising 50% Campbell + 50% Kyoho was the most acceptable in terms of taste and overall acceptability, while the sample comprising 90% Campbell + 10% MBA was the most acceptable in terms of color and aroma.
