摘  要：
采用固相微萃取法和同时蒸馏萃取法提取羊奶粉中的挥发性成分,再经气相色谱-质谱联用仪分析,共检出风味化合物55种,SPME法检出41种,SDE法检出22种,其中共同检测到8种,分别是辛酸、壬酸、癸酸、月桂酸、十二内酯、十四烷、十五烷、2-壬酮。SPME法和SDE法结合使用能较为全面的反映出羊奶粉的挥发性风味物质,且羊奶粉的挥发性风味物质以挥发性酸类成分为主。

摘  要：
Solid micro extraction method and simultaneous distillation extraction method were compared for their sampling effectiveness in GC/MS analysis of aroma components in goat milk powder. The results showed that 55 compounds were obtained from goat milk powder. 41 volatile components were identified by SPME method and 22 by SDE method. And eight of them were the same components,including octanoic acid,nonanoic acid,n-decanoic acid,dodecanoic acid,dodecalactone,tetradecane,pentadecane and 2-nonanone. If combining these two methods,the shortage could be made up and the identification of aroma compounds in goat milk powder would be more efficient and that mainly consisting of volatile acids.
