Abstract

In a determinate sense, Maillard reaction is identified with generation of brown-colored compounds or melanoidins in the reaction environment. Despite this fact, the stage of colored compound formation is episodically studied only [7]. It is established that coloring is related to formation of highly-molecular compounds (> 12000 Dalton) or melanoidins. As a rule, this mass contains heterogenic mixture of melanoidins, and each of them has the different absorption maximum. The intensity of color of our compound is predetermined by high concentration of these compounds, which have intense absorption in the ultraviolet region. Using the similar techniques, we have studied the distribution of melanoid pigment (λ = 470 nm) among low-molecular (<3500 Dalton) and highly-molecular fractions, in reaction mixture obtained via interaction of m-aminobenzoic acid and D-glucose. Results are given in the first figure. Components, which didnt enter into reaction have been determined during reaction, in samples taken from reaction mixture in the definite intervals of time. Reaction mixture has been divided on paper or in thin layer. index terms- Maillard reaction, m-aminobenzoic acid, p-aminobenzoic acid, pH - metre, melanoid pigment.
