摘要/Abstract

摘要： 采用有机溶剂法和超临界CO2流体法提取茶树籽油，并对这两种方法提取的茶籽油进行气相色谱-质谱分析和不同时间的加热贮存实验，分析利用不同方法提取的茶籽油的主要的理化指标和脂肪酸组成。结果表明：用超临界CO2流体法萃取的茶籽油具有较高的碘值，较低的过氧化值和酸值。脂肪酸组成分析结果显示，超临界CO2法萃取的茶籽油不饱和脂肪酸含量高于石油醚萃取的茶籽油。加热贮藏实验中，两种方法提取的茶籽油均有较好的抗氧化能力。

Abstract: The fatty acid composition of tea seed oils obtained by organic solvent extraction and supercritical carbon dioxide extraction was analyzed by GC-MS and their main physiochemical properties were measured. After dry-heat treatment at 100 ℃ for different hours, the changes in acid value and peroxide value were also determined. The tea seed oil obtained by supercritical carbon dioxide extraction had higher iodine value and lower peroxide value and acid compared to the tea seed oil obtained by organic solvent extraction. Moreover, the former showed higher unsaturated fatty acid content. However, both tea seed oils exhibited a good antioxidant capacity.

Key words: tea seed oil, SFE, heating, fatty acid
