Short Communication


Reaction of tryptophan, tryptophan methyl ester and tryptamine with methylglyoxal (a physiological α-oxoaldehyde), which resulted in β-carboline formation, showed that this type of nonenzymatic (Maillard) reaction could spontaneously occur in living organisms or during commercial or domestic food processing and storage.

Keywords: Methylglyoxal – Tryptophan – Tryptamine – β-Carboline – Maillard reaction
