摘要
采用固相微萃取-气质联用仪分析了啤酒花的挥发性成分,考察了不同萃取纤维、萃取时间和萃取温度,对所鉴定出的化合物积分面积的影响。确定了固相微萃取的优化条件为:PDMS萃取纤维、萃取时间20min,萃取温度60℃,此时共鉴定出44种物质,其中烃类化合物有12种,α-石竹烯31.738%、α-蒎烯18.207%,烃类含氧有机挥发化合物有32种,其中丁酸叶醇酯相对含量较高为7.200%。
The volatile components of hops were extracted and analyzed by soli d phase microextraction-gas chromatography-mass spectrometry method（SPME-GC-MS）. The effects of different SPME fibers, extraction times and extraction temperatures on the peak areas of obtained components were investigated, The results showed that the optimal SPME extraction parameters were： polydimethylsiloxane （PDMS） fiber, extraction time 20 min and extraction temperature 60℃, by which 44 volatile components were identified, including 12 hydrocarbons and 32 oxygen-cuntaining organic compounds. In hydrocarbons, there were 31.738% α-earyophyllene and 18.207% α-pinene. The content of hexenyl butyrate was relatively high in oxygen-containing organic compounds as 7.200%.
