气相色谱法测定食醋中环己基氨基磺酸钠

Determination of Sodium Cyclamate in Vinegar by Gas Chromatography

采用气相色谱法对食醋中的环己基氨基磺酸钠含量进行了测定,试验结果如下:样品加标平均回收率在90.7%~95.5%之间,相对标准偏差在2.7%~5.1%之间。结果表明利用气相色谱分析,环己基氨基磺酸钠的平均回收率较高,适合食醋中环己基氨基磺酸钠的测定。

The content of sodium cyclamate in vinegar was measured by gas chromatography,and the results were as follows：the average recovery rate were between 90.7 % and 95.5 % with the relative standard deviations of 2.7 %-5.1 %.The results showed that the average recovery rate of sodium cyclamate was higher.So it was proved to be a accurate method to analyze the sodium cyclamate in vinegar.
