| 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... |
