不同萃取头萃取月盛斋清香牛肉挥发性成分

volatile compounds of Yueshengzhai Fragrant Beef extracted

摘要:

分别采用65um PDMS/DVB、75um CAR/PDMS、50/30um DVB/CAR/PDMS 3种萃取头提取月盛斋清香牛肉挥发性成分，经气相色谱-质谱联用( GC-MS)对挥发性成分进行鉴定, 分析比较3种萃取头提取的挥发性成分差别，确定适宜的萃取头。3种萃取头共检测出53种挥发性化合物，通过对三种萃取头萃取效果的比较，发现75um CAR/PDMS萃取头对月盛斋清香牛肉的挥发性化合物的萃取较有利。

Abstract:

The volatile compounds of Yueshengzhai fragrant beef were extracted by solid phase microextraction with three different solid phase microextraction fibers：65um PDMS/DVB，75um CAR/PDMS and 50/30um DVB/CAR/PDMS. Volatile compounds were identified by gas chromatography-mass spectrometry. Comparison the difference of volatile compounds extracted with different solid phase microextraction fibers, and then found the fit solid phase microextraction fiber. 53 volatile compounds were extracted by them. Comparison with the extracted outcome, 75um CAR/PDMS was the best solid phase microextraction fibers for extracting volatile compounds of Yueshengzhai fragrant beef.
