Reactivity of thermally treated α-dicarbonyl compounds

The degradation reaction of thermally treated 3-deoxy-d-erythro-hexos-2- ulose and methylglyoxal, both key intermediates in Maillard chemistry, was investigated. Different analytical strategies were accomplished to cover the broad range of formed products and their different chemical behavior. These involved HPLC-DAD and accordingly LC/MS analysis of the quinoxaline derivates, GC/MS analysis of the acetylated quinoxalines, and GC-FID analysis of the decyl ester of acetic acid. As a main degradation product of 3-deoxy-d-erythro-hexos- 2-ulose, 5-(hydroxymethyl)furfural could be identified. At alkaline pH values, 3-deoxy-d-erythro-hexos-2-ulose generated various acids but no colored products. In contrast, thermal treatment of methylglyoxal yielded high molecular weight, brownish products. A dimer of methylglyoxal, first precursor for aldol-based polymerization of methylglyoxal, could be clearly identified by GC/MS.

Reactivity of 1-deoxy-D-erythro-hexo-2,3-diulose; A key intermediate in the maillard chemistry of hexoses

Degradation of 1-deoxyhexo-2,3-diulose, a key intermediate in Maillard chemistry, in the presence of L-alanine under moderate conditions (37 and 50 °C) was investigated. Different analytical strategies were accomplished to cover the broad range of product

TREATMENT OF SUGAR SOLUTIONS

A process for treating a solution containing sugar and α-oxoaldehydes, comprising the step of adding a catalyst which comprises an optionally substituted histidine amino acid, such that the α-oxoaldehydes are catalytically converted to aldonic acids.
