摘 要:采用固相微萃取采集白胡椒粉的挥发性成分,用色谱/质谱法分析鉴定,并用总离子流色谱峰的峰面积进行归一化定量分析其风味成分,鉴定出石竹烯(20.88%),1-甲氧基-4-(2-丙烯基)苯(20.57%),β-水芹烯(15.27%),3-蒈烯(14.56%),1-甲基-3-异丙基苯(3.62%),β-蒎烯(2.69%),芳樟醇(2.69%),香叶烯(2.36%),δ-榄香烯(2.10%),胡椒烯(1.32%)等48种化合物。The flavours in white pepper powder (Piper Nigrum L) were determined by gas chromatographymass spectrometry. The volatile components were headspace-sampled using solid-phase microextraction (SPME), by inserting a 65 gm CW/DVB fiber extractor at 25±5℃ for 40 min and then desorhed in a GC injector at 250℃ for 5min. A capillary column of fused silica CP-Sil 8 was employed in GC/MS analysis. The chemical constituents were separated and identified as β-caryophyllene (20. 88%), benzene, 1-methoxy-4-(2-propenyl) (20. 57 %), β- phellandrene (15. 27%), 3-carene(14. 56%), m-cymene(3.62%), β- pinene (2.69%), linalool (2.69%), myrcene (2.36%), δ-elemene (2.10%), α-copaene (1.32%), and a total of 48 volatile compounds were identified.
