摘要
红花山茶油是具有高单不饱和脂肪酸含量和丰富活性物质的特有茶油品种。采集浙江代表性红花山茶籽11种,分析出仁率和籽仁常规营养指标等原料性状,并通过超临界CO_2法萃取山茶油进行脂肪酸组成以及活性物质含量测定。结果表明,干基籽仁粗脂肪为57.31%～68.78%,粗蛋白6.92%～10.64%,总糖质量分数20.41%～28.90%;超临界萃取红花山茶油的油酸质量分数为81.93%～84.42%,不饱和脂肪酸质量分数为87.81%～89.88%,α-维生素E为36.23～58.46 mg/100 g、角鲨烯为16.80～53.56 mg/100 g、茶多酚为43.44～76.76μg/g、茶皂素为2.36～4.86 mg/g。浙江红花山茶籽仁粗脂肪均值,油中油酸质量分数和茶多酚含量均高于普通山茶油,其中油酸质量分数优于其他品种红花山茶油;通过灰色关联度法分析浙江红花山茶籽性状、油品质指标得到最优的采样地均为常山县芳村镇。
Safflower camellia oil is a special kind of camellia oil with high monounsaturated fatty acid content and rich active substance,and its nutrition value is superior to normal camellia oil.In this paper,11 kinds of representative safflower camellia seed from Zhejiang Province were collected to analyze the raw material characters,such as conventional nutrition index and producing-kernel ratio,and the fatty acid composition and active substance content were measured in the camellia oils extracted by supercritical CO2 method.The results showed that the crude fat content of dried seed kernel was 57.31%~68.78%,crude protein 6.92%~10.64%,and total sugar content was 20.41%~28.90%.In the camellia oil,oleic acid mass fraction was 81.93%~84.42%,unsaturated fatty acid mass fraction was 87.81%~89.88%,alpha vitamin E was 36.23~58.46 mg/100 g,squalene was 16.80~53.56 mg/100 g,tea polyphenol was 43.44~76.76μg/g,and tea saponin was 2.36~4.86 mg/g.The mean crude fat content of dried seed kernel,oleic acid mass fraction and tea polyphenol content of Zhejiang safflower camellia oil were all higher than that of normal camellia oils,and oleic acid mass fraction was higher than that of other safflower camellia oils.By the analysis of grey correlation degree method,Fangcun town in Changshan county was considered as the optimal sampling site on the basis of comprehensive comparison of raw material properties and oil quality indexes.
