포도주스는 건강에 유익한 phenolic compounds의 함량이 풍부하여 최근 많은 주목을 받고 있다. 본 연구에 사용된 Campbell 포도주스는 Sample A(씨와 줄기를 첨가하지 않은 경우), Sample B(씨만 첨가한 경우), Sample C(씨와 줄기를 첨가한 경우)의 세 가지로 제조하여 포도 씨와 줄기의 첨가 가 포도주스의 성분, 관능적 특성, 기능적 특성에 미치는 영향을 시험하였다. 포도주스 제조 시 포도 씨와 줄기의 첨가는

Grape juice, one of the most valuable fruit derived product has large amounts of phenolic compounds which provide many of the health benefits. Campbell grape juice, divided into Sample A(without seeds and stems), Sample B(with seeds only), Sample C(with seeds and stems) were processed and assessed for its components, sensorial attributes and functional properties as influenced by the addition of seeds and stems. The presence of seeds and stems in the processing of Campbell grape juice has significant effects on pH and total soluble solids() but showed no significant effects on other physicochemical and color properties and corresponds to an increase in total phenolics, radical scavenging activity, total anthocyanin and total flavonoid The sensory evaluation showed that there is no significant differences among the samples but were all liked moderately to very much by the panelists. The result of this study demonstrated that seeds and stems can be included in the processing of Campbell grape juice as it enhances the juice functional properties without altering its physicochemical and sensorial properties.
