【摘要】：采用顶空固相微萃取-气相色谱-质谱(headspace solid phase microextraction-gas chromatography-mass spectrometry,HS-SPME-GC-MS)联用技术对新疆胡麻油挥发性成分测定分析进行优化,以期获得HS-SPME-GCMS分析胡麻油挥发性香气的最佳条件。结果表明,采用DVB/CAR/PDMS萃取头,在磁力搅拌条件下,胡麻油SPME最佳萃取条件为萃取温度50℃、萃取时间40 min、解吸时间4 min,在该条件下采用HS-SPME-GC-MS鉴定出的胡麻油挥发性物质达到46种,主要包括醛类、酮类、醇类、酸类、酯类、烷烃类、杂环类及其他类物质,其中醛类、杂环类和醇类总相对含量较高,分别为30.14%、12.73%和9.25%,分离鉴定效果较好。
[Abstract]:The determination of volatile components of flax oil in Xinjiang was optimized by headspace solid-phase microextraction (SPME) -gas chromatography-mass spectrometry (GC-MS) combined with headspace solid phase microextraction-gas chromatography-mass spectrometrymetric HS-SPME-GC-MS. in order to obtain the best conditions for the determination of volatile aroma of flax oil by HS-SPME-GCMS. The results showed that the optimum extraction conditions for SPME of flax oil were as follows: extraction temperature 50 鈩，
