Abstrakt: Solid phase extraction (SPE) is a technique widely used in food analysis for the isolation of analytes. Herein, we proposed a novel application of SPE to extract vaporised propionic acid, a common preservative, from a heated sample solution. A sample was heated under acidified conditions and the resulting steam was directly passed through an SPE column to extract the propionic acid, followed by elution and HPLC analysis. Here, the extraction on the SPE column ensures direct capture of propionic acid. The results demonstrated excellent linearity (R 2  greater than 0.999) and recoveries of 89.9%-97.6% with intra- and inter-day precisions lower than 3.9%. To the best of our knowledge, no study has investigated the applicability of SPE to an analyte vaporised in the headspace of food products. The proposed method is promising in its application to various volatile compounds and in the routine analysis of propionic acid in food.
