江西地区油茶籽的含油率和脂肪酸组成的调查与分析

Oil content and fatty acid composition analysis of camellia seeds oleifera in Jiang-xi

本文对江西地区2011年产的38个油茶籽的含油率和脂肪酸组成进行了分析。结果表明：油茶籽含油率在20.48%~49.84%之间,平均为37.07%。油茶籽油脂肪酸主要是由棕榈酸、硬脂酸、油酸、亚油酸、花生一烯酸等脂肪酸组成,棕榈酸含量平均值8.19%;硬脂酸含量平均值2.48%;油酸含量平均值81.02%;亚油酸含量平均值7.74%;花生一烯酸含量平均值0.46%,主要不饱和脂肪酸油酸和亚油酸含量平均达到了88.76%,说明江西地区的油茶籽油符合高品质食用油的标准。

The oil contents of 38 Camellia oleifera seed were determined, and the fatty acid compositions of the camellia seed oils were analyzed by GC. The results indicate that： the oil content was between 20.48%~49.84%, and the average was 37.0%. Camellia oleifera seed oil was mainly composed of palmitic acid, stearic acid, oleic acid, linoleic acid and eicosenoic acid. The average content of palmitic acid was 8.19%, the average content of stearic acid 2.48%, the average content of oleic acid 81.02%, the average content of inoleic acid 7.74%, and the average content of palmitic acid 0.46%. The average percentage of unsaturated fatty of oleic acid and linoleic acid was 88.76%, the result shows that the camellia oleifera seed oil was the high quality of vegetable oil.
