Determination of 2 Sweeteners in Grape by UPLC-MS/MS
Establishing a method for the qualitative analysis and quantitative detection of sweeteners such as sodium cyclamate and neotame in grape samples using a ultra high performance liquid chromatography triple quadrupole mass spectrometer system.The samples are prepared and injected into the instrument after extraction,utilizing a multiple reaction monitoring mode and negative ion scanning.There is a good linear relationship in 1~50 ng·mL-1,with a spike recovery rate of 87.6%to 96.8%and the relative standard deviation≤5.8%.This method is characterized by its simplicity in sample preparation,high detection efficiency,accuracy,and good repeatability.It can be used for the detection of certain sweeteners in fresh grape samples.
