• Some Novel Meatlike Aroma Compounds from the Reactions of Alkanediones with Hydrogen Sulfide and Furanthiols

  The products of reactions of hydrogen sulfide with 2,3-butanedione and with 2,3-pentanedione in dilute ethanolic solution were analyzed by CC-MS and CC-odor port analysis. Components were also collected from the GC column and analyzed by H-1 NMR. Mercaptoketones were formed which readily oxidized to the corresponding disulfides with traces of mono- and trisulfides. When 2-methyl-3-furanthiol or 2-furylmethanethiol was added to the reaction mixtures, a series of disulfides containing alkanone, 2-methyl-3-furyl and 2-furanmethyl moieties were formed. Some of these compounds have been found recently in the volatiles of cooked meat and in meatlike model systems. GC-odor port evaluation of the components of the reaction systems showed that disulfides containing the 2-methyl-3-furyl group had meaty aromas, whereas those without this group were sulfurous or onion-like in character.

  The volatiles of eight commercially available meat flavorings were enriched by dynamic headspace extraction. The resulting aroma extracts were analyzed by high-resolution gas chromatography and gas chromatography/mass spectrometry (GC/MS). Among the compounds identified were 16 sulfur-containing furans. 2-Methyl-3-(ethyldithio)furan, 1-[(2-methyl-3-furyl)dithio]-2-propanone, and the spectroscopic data of 3-[(2-methyl-3-furyl)dithio]-2-butanone, 2-[(2-methyl-3-furyl)dithio]-3-pentanone and 3-[(2-methyl-3-furyl)dithio]-2-pentanone are reported here for the first time. Possible formation pathways are discussed.
