Abstract:

The aim of this study was to monitor aroma and hazardous compounds in Maillard reaction products (MRPs)
derived from model systems consisting of amino acids (cysteine, glycine and glutamic) and reducing sugars (xylose and
glucose). The results showed that more kinds of amino acids participating in the Maillard reaction could result in the
formation of more volatile compounds and more abundant flavors. The reaction in the presence of glycine could generate
less acrylamide, while a higher amount of acrylamide could be formed in the presence of glutamic acid. The type of reducing
sugar had no impact on the generation of acrylamide. Higher content of 5-hydroxy methylfurfural (5-HMF) in MRPs was
derived from glycine model system, while model systems containing cysteine, glycine or xylose produced lower content of
5-HMF. The amount of acrylamide and 5-HMF was in the safe range under our experimental conditions.

Key words: Maillard reaction, aroma components, acrylamide, 5-hydroxymethylfurfural (5-HMF)
