In this paper, a rapid method for the determination of sodium cyclamate in food was established by improving the sample processing method and using capillary column as the separation column to optimize the gas chromatographic analysis conditions. The detection limits, precision and recovery of the method were also evaluated. Finally, the method is applied to the determination of cyclamate in practical work, the result is accurate and reliable. I. Materials and Methods 1.
