摘　　要：利用顶空(HS)技术结合气相色谱-质谱(GC-MS)联用仪建立了一种快速测定出窖酒醅酒精度的方法。通过优化参数确定了该方法的最佳分析条件。结果表明,该方法检出限为0.099 g/100 g,回收率为88.66%~93.23%。该方法与国标密度瓶法相比,具有简便、快捷、高灵敏度等优点。可以作为酒醅酒精度检测的参考方法。A method for rapid determination of alcohol content of pit-exit fermented grains by HS-GC-MS had been developed. The results suggested that the detection limit was 0.099 g/100 g and the recovery was 88.66 % to 93.23 %. Compared with international standard density bottle method, this method had the advantages of simplicity, rapidness and high sensitivity. It could be used as a reference method for detecting the alcoholicity of fermented grains.
