| 摘 要： | 采用CO2超临界萃取法(supercritical carbon dioxide extraction，SCDE)和异丙醇溶剂法(isopropanol solvent extraction，ISE)萃取小米谷糠油，并用气相色谱仪和荧光分光光度计对其中的脂肪酸组成、VE、总甾醇、磷脂含量和色泽进行分析。结果表明：小米谷糠油中亚油酸的含量远远高于其他食用植物油，达到71.82%。SCDE法提取的小米谷糠油与ISE法相比，前者的不饱和脂肪酸含量比后者下降了0.11%，而C14至C22饱和脂肪酸升高0.93%；SCDE法的VE和甾醇含量分别比ISE法高20.64%和34.82%；磷脂含量下降99.60%，并且色泽较浅。

| Abstract: | Supercritical carbon dioxide extraction(SCDE) and isopropanol solvent extraction(ISE) were employed to extract millet bran oil.The fatty acid composition and the contents of sterol,vitamin E and phospholipid as well as the color change of the obtained samples were determined by gas chromatography and fluorescence spectrometry.The results showed that the content of linoleic acid in millet bran oil was even higher than other edible oils,which was up to 71.82%.The contents of unsaturated fatty acids and phosph... |
