摘要
Abstract
A method for simultaneous determination of deoxynivalenol,3-Acetyl deoxynivalenol,15-Acetyl deoxynivalenol and zearalenone in pastry had been developed by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS).The determination was finished within 4 minutes.The results showed that all of the 4 mycotoxins had good linearity in the range of 5～1000 μg/kg with the correlation coefficients(R2) better than 0.997.The limits of detection(LODs) of DON and ZEN were 1.0 μg/kg,3-AcDON and 15-AcDON were 1.5 μg/kg.The results of 134 pastry samples determined by the method showed that all of the 4 mycotoxins were detected in the tested samples.The detection rate were 2.2％,78.4％,3.0％ and 5.2％ for ZEN,DON,3-AcDON and 15-AcDON.The maximum residual contents were lower than national food safety limited requiements.关键词
