Development and Validation of a Stable Isotope Dilution Headspace-SPME-GC/MS Method for the Determination of Vanillin in Fragrant Vegetable Oils.

ABSTRACT: It has been reported that vanillin has been intentionally added to enhance the taste and flavor of low-quality vegetable oils. Therefore, it is crucial to investigate the accurate concentrations of vanillin in three types of fragrant vegetable oils commonly consumed in China. In this study, a method has been developed for the quantification of vanillin in commercial fragrant vegetable oils using the stable isotope dilution assay (SIDA) and headspace-solid-phase microextraction (HS-SPME) coupled with gas chromatography/mass spectrometry (GC/MS). The limit of detection (LOD) and limit of quantification (LOQ) of the analyte were determined to be 20 µg kg^-1 and 50 µg kg^-1, respectively. The validation study demonstrated that the recoveries ranged from 89% to 101%, with in
