Abstract

The volatile compounds from equal amounts of both wheat and rye bread crust were isolated and fractionated, and their aromagrams were compared. The flavour compounds that were sensorially detectable in the HRGC-effluents were identified by mass spectrometry. 2-Acetyl-1-pyrroline was found to be a character-impact compound in wheat bread crust. In comparison to rye crust, wheat contained only 16 of the 30 neutral/basic rye aroma compounds. Although acetylpyrazine was found in both crusts, other compounds: 2-acetylpyradine, 5-methyl-6,7-dihydro-5H-cyclopenta(b)pyrazine and 2-acetyl-1,4,5,6-tetrahydropyridine, all having crust-like odours, were only found in rye.
