摘　　要：建立了用气相色谱对调味面制品中甜蜜素含量进行测定的方法,试验采用FID检测器,外标法,自动进样,在建立的气相色谱条件下进行了方法验证,结果表明:甜蜜素检出限为0.01g/kg,(进样量为1μL,S/N=3),标准曲线的线性范围分别为:0.02~1.0mg/mL(r=0.99992),样品加标回收率为:90.8%~98.5%,相对标准偏差RSD(n=10)甜蜜素3.78%。该方法回收率高、重现性好,是一种准确稳定操作快速简单的检测方法。A method for the determination of sodium cyclamate in flavored flour products by gas chromatography was established. The method used FID detector,external standard method and automatic sampler.The results showed that the detection limit of Sodium cyclamate was 0.01 g/kg and the linear range of standard curve was 0.02 ~ 1.0 mg/mL(r=0.99992),the recovery of standard was 90.8% ~ 98.5%,the relative standard deviation RSD(n=10)of sodium cyclamate was 3.78%.The method has high recovery rate and good reproducibility,and is fast. It is simple detection method with accuracy and stable in operation.
