In a series of 13C-isotopic labelling experiments, Maillard reaction pathways of intact or fragmented sugars to N-alkylpyrroles and furan compounds were elucidated. The polymerizing activity of these compounds has been investigated. Complex mixtures of polymers and individual oligomers were characterized by FAB-/MALDI-TOF-MS and 1H/13C-NMR spectroscopy. The antioxidative activity of individual compounds was assessed by the Fe(III)-thiocyanate method and the DPPH-reduction assay.
