摘要

Abstract

A high performance liquid chromatography method for the determination of the artificial sweetener acesulfame K in food was developed.Ultrasonic-assisted aqueous extraction followed by the removal of protein impurities by adding zinc acetate and potassium ferrocyanide was used for sample preparation.Acesulfame K was separated on a C18 column using methanol-0.02 mol/L ammonium acetate(5.5:94.5,V/V) as mobile phase at a flow rate of 0.8 mL/min and detected using a diode array detector(DAD) at 230 nm.The column temperature was set at 30 ℃ and the injection volume 5μL.The retention time of acesulfame K was about 4.6 min.The detection limit of the developed method was 1.7 mg/kg,and the linear range was between 1.0 and 50.0μg/mL.The mean spike recoveries for acesulfame K in a blank juice sample exceeded 90%,with a relative standard deviation below 2%(n=6).In this method,acesulfame K was extracted using water as solvent with the assistance of ultrasound,and purified by precipitation.The method proved to be simple,rapid,accurate and practical.
