Stereodifferentiation of some chiral aroma compounds in wine using solid phase microextraction and multidimensional gas chromatography
The stereodifferentiation of some chiral components of importance for the character or intensity of wine aroma was achieved with headspace solid phase microextraction and multidimensional gas chromatography coupled to mass spectrometry. Chiral evaluation of linalool and 2,3-butanediol is performed in less than 75. min (overall analysis time) using a polydimethylsiloxane/divinylbenzene fibre during the sample concentration step and permethylated β-cyclodextrin as the chiral stationary phase in the main column of the multidimensional system. Enantiomeric excesses of linalool and percentage values of 2,3-butanediol stereoisomers were determined in three different white wines. © 2010 Elsevier Ltd.
