摘　　要：本文通过改进提取方法,利用气相色谱仪测定环己基氨基磺酸钠含量,建立了糕点中环己基氨基磺酸钠含量的快速测定方法。环己基氨基磺酸钠标准曲线线性范围为0.01~0.50 mg·mL^(-1),线性相关系数为0.999 96,测定值的相对标准偏差(n=6)为1.16%~3.64%,回收率为93.0%~104.2%,方法检测限为0.006 g·kg^(-1),定量限为0.018 g·kg^(-1)。结果表明,该方法可以快速准确测定糕点中甜蜜素的含量。A method was developed for determination of sodium cyclamate in pastray by gas chromatograph, with improved extraction. The content of sodium cyclamate showed a good linear in the range of 0.01~ 0.50 mg·mL^(-1), and the linear correlation coefficient was 0.999 96. The relative standard deviations of the determined values(n=6) ranged from 1.16% to 3.64%. The recovery rate was between 93.0% and 104.2%. The limit of detection was 0.006 g·kg^(-1)and the limit of quantification was 0.018 g·kg^(-1). The results showed that this method fastly and accurately determined the content of sodium cyclamate in pastray.
