| Abstract: |
| In order to effectively improve detection efficiency of maltol, ethyl maltol, vanillin, methyl vanillin and ethyl vanillin in edible vegetable oil, a liquid chromatography-mass spectrometry (HPLC-MS/MS) method was established for the simultaneous determination of maltol, ethyl maltol, vanillin, methyl vanillin and ethyl vanillin in edible vegetable oil.The samples were extracted by acetonitrile and defatted by n-hexane,then methanol-0.1% formic acid aqueous solution was used as the mobile phase for gradient elution, electrospray ionization was used to conduct multiple reaction monitoring scanning under positive ion mode, and 5 kinds of spices were quantitatively determined. The results showed that the linear relationships were good between the mass fraction of spices and peak areas, and the correlation coefficients were higher than 0.998,the detection limits were 2.3-19.5 μg/kg, the quantitation limits were 7.7-65.0 μg/kg,the recovery rate were 85.0%-107.8%, and the relative standard deviations were less than 5.0%.The method is simple, accurate and sensitive. It is suitable for the simultaneous determination of maltol, ethyl maltol, vanillin, methyl vanillin and ethyl vanillin in edible vegetable oil, which can improve the detection efficiency effectively. |
