Abstract:

The sweeteners are separated by high performance liquid chromatography (HPLC) with 5 mmol/L ammonium formate-acetonitrile gradient elution and quantified by charged aerosol detector (CAD) to establish a method for the simultaneous determination of eight artificial sweeteners in food by HPLC-CAD. The linearity of acesulfame, sodium saccharin, cyclamate, sucralose, aspartame, alitame, advantame and neotame in the range is good, and the correlation coefficient is above 0.999. The limit of detection and quantitation is 5~30 μg/L and 20~150 μg/L, respectively. The recovery rates are 88.5% to 102.8%, and the relative standard deviations are less than 2.16%. The method is simple, rapid, sensitive and reproducible, and can be used for the detection of 8 sweeteners in food.
