中文摘要: 建立气相色谱内标法测定蜜饯中甜蜜素含量的方法。蜜饯中的甜蜜素经水超声提取后，以乙酸丁酯为内标物，采用HP-5毛细管柱，程序升温：初温60℃保持6 min，以40℃/min升温至200℃保持3 min，进样口温度230℃，氢火焰离子化检测器（flame ionization detector，FID）260℃进行检测。当样品的称样量为5 g时，蜜饯类食品中的甜蜜素的检出限为0.008 g/kg，方法的标准曲线线性良好，相关系数为0.999 0，平均回收率在88.46%～104.26%之间，相对标准偏差为3.97%。
Abstract:To establish a determination method for sodium cyclamate in candied fruit by gas chromatography（GC）with internal standard.Sodium cyclamate was extracted with water.A HP-5 capillary column was used.Temperatureprogramming：60℃（6min）→40℃/min→200℃（3min）.Theinjectiontemperaturewas230℃，FID detector temperature was 260℃.When testing sample was 5 g，the detection limit was 0.008 g/kg.The correlation coefficients of the calibration curves was 0.999 0.The average recovery rates were in the range of 88.46%-104.26%.The relative standard deviations was 3.97%.
