| Abstract: | A simple, rapid and sensitive method for direct determination of free fatty acids in wineswas described by the authors. It is accomplished on a fused quartz capillary column coated withOV-17. The ion m/z 60 of the base peak in the mass of spectrum of C_4-C_(18) normal fatty acidswas used in GC/MS SIM. The contents of 12 free fatty acids in Maotai, Rare Distillate andYaxijiaojiu have been determined by this method. |
