Abstract:

Objective: to establish a simple, accurate and sensitive method for determination of cyclamate in preserved fruits by high-performance liquid chromatography with pre-column derivatization. Method: Through the reaction between cyclamate and sodium hypochlorite under acid medium, N,N-dichloro- cyclohexylamine was determined by UV-HPLC. Results: The detection limit is 0.05 g/kg. The calibration curve is linear in the range of 0.02 to 1.00 mg/ml with a correlation coefficient of 0.9995. The relative standard deviation is 1.56% to 4.49% and the recovery rate is in the range of 91.5% to 98.5%. The determination result has no significant deference from that by the method of GB5009.97 — 2003. Conclusion: The method is sensitivity, simple and stable and has good repetition. It can be used for the determination of cyclamate in preserved fruit.

Key words: cyclamate, high-performance liquid chromatography, pre-column derivatization
