The aim of the work was to determine the vegetable oil with the highest linoleic acid content by gas chromatography (GC). Eleven vegetable oil samples and one animal fat sample were analyzed. A mass spectrometer (MS) was used as the detector, which offers high selectivity and sensitivity. The GC-MS conditions were optimized to obtain well-separated spectra of individual fatty acid esters. The analytical method was partially validated and confirmed to have adequate linearity, precision, accuracy and repeatibility. Sunflower oil had the third highest linoleic acid content, but due to its accessibilizy, affordability and other physical properties, it proved to be the most suitable vegetable oil for emulsion electrospinning of nanofibers. Electrospun nanofiber fabrics with a high surface area to volume ratio have been studied several times in recent years as a possible solution for extending the shelf life of fruit and vegetables. Emulsion system for electrospinning nanofibers contain an oil and water phase in which linoleic acid is a biological precusros for the biosynthesis of hexanal, which inhibits the ripening of fruits and vegetables due to its antimicrobial activity.
