[Objective]The purpose of this study is to find and establish a simple and efficient method used to detect the fatty acid composition and content in the milk. [Method]Gas chromatography （GC-FID） method was used to separate the milk fatty acid composition by using the Agilent HP-88 fatty acid methyl esters capillary column and temperature programmed method, quantitative retention time was used for quantify by qualitative and peak area percentage method. [Result]The results showed that the fatty acid in milk was well separated. The recovery and precision of detection method were 99. 588% and 2. 600, respectively, with a high accuracy and repeatability. [Result]The experimental method could be used as a milk fatty acid detection technology for promotion and application.
