    Reactions of reductones and methylene-active compounds with Maillard carbonyl intermediates.

  • Original language description

    The reducing activity of principal low-molecular non-nitrogen Maillard reducing intermediates formed in binary mixtures with several kinds of important Maillard carbonyl products was evaluated. Only norfuraneol and 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one (DDMP) are able to yield active addition products. It was found that the tested compounds with reactive methylene group are notably transformed to reducing products only when reacted with cyclic compounds possessing reactive formyl group, suchas derivatives of furan-2-carbaldehyde, and also with -hydroxycarbonyl products of sugar fragmentation such as glycolaldehyde and glyceraldehyde. Several active condensation products were isolated and identified, such as stereoisomers of 2 [(2-furyl)methylidene]-4 hydroxy-5-methyl-2H-furan-3-one formed from norfuraneol and furan 2 carbaldehyde, 4 hydroxy-2-[2-(5-hydroxymethylfuryl)methylidene]-5-methyl-2H-furan-3-one (norfuraneol and 5-hydroxymethylfuran-2-carbaldehyde) and 4 hydroxy-5-
