Abstract

The article presents experimental data on the study of heterocyclic aromatic amines formation in model matrices consisting of amino acids (8 essential, glutamic acid and aspartic acid), carbohydrates (sucrose, lactose) and creatine. The results of the studies showed that carbohydrates in the reaction of MeIQx and PhIP formation can exhibit both inhibitory and catalytic properties in the reaction of their formation. Of all the studied matrices, in the samples with phenylalanine noted the highest amount of PhIP, its content reached 27837.79 ng/g, based on which it is fair to assume that of all the amino acids, phenylalanine is the main precursor in the reaction of PhIP formation. High concentrations of PhIP were also noted in the samples with tryptophan up to 4891.36 ng/g.
