Quantitative analysis of the principal volatile compounds in oak wood by direct thermal desorption (DID) and GC/MS

Abstract

This work proposes one method of quantifying the principal volatile compounds in oak wood using the direct thermal desorption (DTD) technique coupled with GC/MS. These compounds have a particular sensory importance in wines aged in oak wood barrels: furfural, trans and cis-β-methyl-γ-octalactones, eugenol, vanillin and syringaldehyde. The described method requires practically no sample handling and is precise and sensitive. © EDP Sciences, Wiley-VCH.
