Objective To detect sodium cyclamate in food by gas chromatography method.Methods Sodium cyclamate was reacted with nitrite in sulfuric acid medium,the generated cyclohexanol nitrate was separated by large-diameter capillary column DM-FFAP(30m×0.53 mm×0.5 μm),and detected by GC-FID.Results The linear range was 0.010-2.0 mg/ml(r= 0.999 9),the relative standard deviation was 3.2%-6.1%,and the recovery was 90.0%-105.2%.Conclusion The method is simple,rapid,accurate and more reliable for the determi...
