A method for the determination of sodium cyclamate in food by headspace-gas chromatography was developed. This method was qualified using the derivative cyclohexene and nitrocyclohexane ,and quantified using cyclohexene.At the same time the equilibrium temperature, the equilibrium time and the mass concentration of sulfuric acid were optimized. The method showed good linearity over the range from 0.010 to 0.20 mg/mL(R2=0.994 9).The limit of quantification was 0.045 mg/kg. The recovery was 94.4%-109.1%and the relative standard deviation was 1.53%-3.68%. Results showed that this method was simple, sensitive, accurate. Therefore, it is suitable for detection and analysis of sodium cyclamate in food.
