摘要: 应用固相微萃取法采用3种不同萃取纤维,结合气相色谱-质谱联用技术,剖析1种国外奶味香精样品中的挥发性成分。结果表明;以Carboxen/聚二甲基硅氧烷(carboxen/polydimethylsiloxane,CAR/PDMS)为萃取纤维的方法鉴定出39种挥发性成分,以聚二甲基硅氧烷/二乙烯基苯(polydimethylsiloxane/divinylbenzene,PDMS/DVB)为萃取纤维的方法鉴定出41种挥发性成分,以二乙烯基苯/Carboxen/聚二甲基硅氧烷(Divinylbenzene/Carboxen/Polydimethylsiloxane,CAR/PDMS/DVB)为萃取纤维的方法鉴定出40种挥发性成分;3种纤维萃取的分析结果相互补充,共鉴定出51种挥发性成分,其中酯类、醛酮类和内酯类化合物的含量最高,分别为26.12%、25.95%和15.16%,是该种奶味香精的主要组成成分。

Abstract: The volatile composition of a foreign dairy flavoring was analyzed by GC/MS after solid-phase microextraction using 3 different types of extraction fibers. A total of 39, 41 and 40 volatile compounds were identified with CAR/PDMS fiber, PDMS/DVB fiber, and CAR/PDMS/DVB fiber, respectively. The results of the three different kinds of fibers complemented each other, and a total of 51 volatile compounds were identified in this dairy flavor, among which, esters, aldehydes, ketones and lectones were the dominant components and their concentrations (26.12%, 25.95%, and 15.16 %) were higher than those of others.

Key words: solid-phase microextraction, dairy flavoring, volatile components, gas chromatography-mass spectrometer (GC-MS)
