Volatile basic compounds from a heated D-glucose/L-alanine mixture were analyzed by gas chromatography and coupled gas chromatography-mass spectrometry. By comparison of mass spectra with corresponding reference spectra, the following compounds were identified: pyrrolidine, β-picoline, pyrazine, 2-methylpyrazine, 2, 5-dimethylpyrazine, 2, 3-dimethylpyrazine, 2-ethyl-5-methylpyrazine, 2, 3, 5-trimethylpyrazine and 2, 5-dimethyl-3-ethylpyrazine. 2-Methyl-3, 5-diethylpyrazine, 2-methyl-5, 6-diethylpyrazine and two alkylpyrazines with M. W. 164 and 178 were also tentatively identified.
No evidence for the presence of N-nitrosamine with low molecular weight was found.
