Determination of advantame in alcoholic beverages by liquid chromatography-tandem mass spectrometry
Objective To establish a highly sensitive analytical method for the determination of advantame in alcoholic beverages by liquid chromatography-tandem mass spectrometry(LC-MS/MS).Methods The wine samples were diluted 10 times with ultrapure water,filtered through a membrane,and then injected.A Kinetex® Biphenyl 100 Å chromatographic column(100 mm×3.0 mm,2.6 μm)was used,with water and methanol as the mobile phase for gradient elution and separation.An electrospray ionization source(ESI)was adopted for detection in the positive ion scan multiple reaction monitoring(+MRM)mode,and external standard method was used for quantification.Results Advantame exhibited an excellent linear relationship within the mass concentration range of 0.03 to 40.00 μg/L,with a correlation coefficient of 0.9999.The limit of detection was 0.10 μg/kg,the limit of quantification was 0.30 μg/kg.The average recoveries at the 4 different spiked levels of low,medium-low,medium-high and high were 80.8%to 109.8%,and the relative standard deviation was 2.7%to 12.5%(n=6).Conclusion This method has high detection sensitivity,is simple to operate,accurate and reliable,and can be used for the trace analysis and risk assessment of advantame in alcoholic foods,providing strong technical support for scientific supervision of the alcoholic beverage market.
