Abstract: 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.
