Abstract

The influence of the matrix and the isolation and concentration conditions on the enantiomeric excess of filbertone [(E)-5-methyl-2-hepten-4-one] in hazelnuts is studied. In hazelnuts, under mild conditions the filbertone obtained has a higher enantiomeric excess than that one extracted under forced conditions. Enantiomers were separated by inclusion gas chromatography on Chirasil-β-Dex using multidimensional gas chromatography with flame ionization detection and gas chromatography/mass spectrometry in the selected ion monitoring mode.
