中文摘要:

      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。

英文摘要:

      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.
