포도가공시 얻어지는 부산물인 종실의 이용가능성을 타진하기 위하여 일반성분 및 종실지방질을 분석한 결과 일반성분은 총당 $2.78{sim}5.13%$, 조단백질 $7.68{sim}15.37%$, 석유에테르추출물 $11.31{sim}16.96%$, 조회분 $1.81{sim}2.91%$이었다. 포도종실지방은 $89.5{sim}99.3%$의 트리그리세리드로 구성되어 있으며 지방산은 주로 팔미트산$(6.7{sim}9.1%)$, 올레산$(13.4{sim}20.7%)$ 및 리놀레산$(68.1{sim}78.1%)$으로 구성된 올레-리놀레산계 지방질이었다.
Grape seed of five varieties of grapes and their oils were analyzed in terms of their chemical composition, lipid class and fatty acid composition. Grape seed analysis showed that it contained; total sugar:2.78-5.13%, crude protein:7.68-15.37%, petroleum ether extract:11.31-16.96%, ash:1.81-2.91%. Grape seed oil was composed of 89.5-99.3% triglyceride. Total fatty acid was composed mainly of palmitic acid (6.7-9.1%), oleic acid (13.4-20.7%) and linoleic acid (68.1-78.1%), meaning the oil to be oleic-linoleic.
