Development of comprehensive two-dimensional gas chromatography technology for wine research

Abstract

The aim of this project was to evaluate the new technology of comprehensive two-dimensional gas chromatography (GC×GC) for a broad range of application possibilities in the wine analysis area. The technique provides enhanced separation power, and also increased sensitivity for volatile chemical analysis, both of which are relevant for the analysis of aroma components of wine. Gas chromatography is therefore widely used for this type of analysis, but often, insufficient resolution of compounds makes conclusive results difficult to achieve. The model studies that were conducted using GC×GC included general essential oil analysis for technique evaluation, then solid phase microextraction (SPME) of resveratrol from wine, and chiral analysis of selected small aroma compounds from wine.
Based on these studies, further research will be carried out with AWRI on specific projects.
