Characterization of European wine glycerol: stable carbon isotope approach.
Glycerol of about 170 European wines was analyzed using gas chromatography-combustion-isotope ratio mass spectrometry technique. (13)C/(12)C isotopic ratio measurements were performed to characterize glycerol's delta(13)C values of genuine wine samples from European Union wine-producing countries. Glycerol was also successfully dosed using an internal reference, 1,5-pentanediol.
