Abstract

Flavour properties of the individual fractions of aroma concentrate isolated from yeast autolysate Gistex X-II Powder were organoleptically evaluated. Using coupled gas chromatography-mass spectrometry there were identified some volatile substances in the basic and neutral fractions. Alkylpyrazines were found as the major constituents of the basic fraction. Nitrogen and oxygen-containing heterocyclic compounds, phenols and carbonyls were identified in the neutral fraction. The influence of heat treatment on yeast autolysate was also investigated.
