COMPARISON OF LLE, HS-SPME, DI-SPME EXTRACTION METHODS FOR SCREENING THE VOLATILE COMPOUNDS IN FETEASCA NEAGRA WINE
Abstract
Liquid-liquid extraction (LLE), headspace solid phase microextraction (HS-SPME) and direct immersion solid phase microextraction (DI-SPME) techniques, followed by capillary gas chromatography-mass spectrometry (GC-MS), were compared for screening the volatile composition in Feteasca Neagra wine. The compounds were identified by comparing the Kovats indexes and the mass spectra included in the NIST Library. The number of compounds extracted using the three procedures decreased in the following order: LLE-GC-MS, DI-SPME-GC-MS, HS-SPME-GC-MS. Despite of the drawbacks, LLE-GC-MS is a useful technique for extraction, separation and identification of volatile compounds in wine samples.The papers published in the journal are licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License, which permits unrestricted, non-commercial use, distribution and reproduction in any medium, provided the work is properly cited.
