Kinetic Behavior and Mechanism of Inhibition in the Maillard Reaction. IV. Mechanism of the Inhibition

摘要

SUMMARYA general mechanism of inhibition of the Maillard reaction via free radicals or equally reactive species derived from original inhibitors was proposed for typical inhibition by sodium bisulfite. Some inhibitors, such as mercaptans, sulfur, disulfides, and benzoyl peroxide, provided supporting evidence in favor of the proposed mechanism for the inhibition by sulfites. The mechanism involves attack on the chromophoric intermediates and melanoidin precursors by free radicals of the original sulfite inhibitor.Inhibition by bromine was attributed to an attack on enolic double bonds in the proposed intermediates. No hypotheses previously proposed for the mechanism of inhibition by sulfites were found to account satisfactorily for the inhibition of the Maillard reaction.
