title: Volatile sulfur containing compounds in simulated meat flavour and their comparison with the constituents of natural aroma.
abstract: The composition of sulfur containing compounds in simulated meat flavour goods for food industry and obtained through Maillard reaction from bakery yeast autolysate was studied for the first time. Gas chromatographic analysis on a series of four columns of different polarity identified 37 compounds, and structure of 13 from them were confirmed by mass spectrometry. 9 sulfur substances have been previously reported neither for model systems nor natural meat products. It was found that two from four gas chromatographic fractions reminiscent cooked meat aroma correspond to boiled beef. All these fractions were characterized by retention indices and odor description. 25 from identified sulfur compounds were shown to be also inherent for various meat products.
