Abstract

[2H10]-4-Mercapto-4-methylpentan-2-one (d 10-1),[2H2]-3-mercaptohexan-1-ol (d 2-2), and [2H5]-3-mercaptohex-1-yl acetate (d 5-3), deuterated analogues of impact odorants of wines, were used to determine quantitatively the natural compounds in white wines (Muscadet, Sauvignon, and Bacchus) with a stable isotope dilution assay using gas chromatography coupled either with ion trap tandem mass spectrometry (GC-ITMS-MS) or ...
