Abstract: In this paper, the method of determining alcohol in the liquid milk product by headspace gas chromatography was carried out. Through the optiminzed conditions the results of determination are: recovery range 88.5%~108.8%, precision 6.1%, and the linearity range 0~1.0mg/ml. The results showed that the advantage of this method is simple, fast and accurate.
