调味面制品中甜蜜素的测定

目的 测定调味面制品中的环己基氨基磺酸钠(甜蜜素)。方法 采用毛细管气相色谱法(氢火焰离子化检测器FID)测定食品添加剂甜蜜素在调味面制品中的残留量。结果 该法定量线性关系良好, 回归方程为: Y=0.489876X?1.12084(r =0.99976), 最低检测限为: 0.002 g/kg, 加标回收率为85.2%~105.3%。结论 该方法灵敏度高、操作方便、准确、稳定性好, 适合调味面制品中甜蜜素的测定。

Determination of sodium cyclamate in seasoned flour food

Objective To determine the content of sodium cyclamate in seasoned flour food. Methods The content of sodium cyclamate was determined by gas chromatography with FID detector. Results There was a good linear relation, and the regression equation was: Y=0.489876X?1.12084 (r=0.99976). The limit of quantification was 0.002 g/kg. The recovery was from 85.2% to 105.3%. Conclusion The method is sen-sitive, easy to operate, accurate and stable, therefore can be used for sodium cyclamate content determination.
