建立了用气相色谱法测定白酒中四甲基吡嗪含量的方法,并对3种不同酒样进行检测。该外标法在测定酒样时的标准偏差为0.005～0.058,变异系数为2.83%～9.99%,回收率为86%～106%,具有操作简便快捷、精密度好、准确度高的特点。检测结果表明,不同酒样中的四甲基吡嗪的含量有较大差异,可以据此对白酒品质进行评价。

We had developed the method of measuring tetramethylpyrazine content in liquor by GC.In this study,we had detected three different kinds of liquor samples.The standard deviation of external standard method was 0.005～0.058 in the measurement of liquor samples,the coefficient of variation was between 2.83 %～9.99 %,and the recovery was between 86 %～106 %.Such method had the advantages including simple and rapid operation,good precision,and high accuracy.The measurement results suggested that there was great different in tetramethylpyrazine content in different liquor samples,which could be used to evaluate liquor quality.
