The enzymically hydrolyzed quinoa protein (E-HQP) was used as a main precursor of a wide range of thermal process flavours. Identification of the volatile compounds generated from the reaction of E-HQP-xylose model mixture at different initial pH values (5, 6, 7, 8 and 9) was performed using a solid phase microextraction – GC-MS technique. The content of free amino acids, color intensity and radical scavenging activity of the Maillard reaction products (MRPs) formed at each pH were determined The results revealed a great influence of the pH values on chem. composition and odor profile of the generated volatiles. The studies showed that low pH favored formation of furans, furanones and cyclopentanones. In contrast, the pyrazines comprised the highest yield of the total volatiles at pH 9. A pos. correlation was found between increasing the pH values and browning intensity of MRPs. The antioxidant activity of MRPs and total content of free amino groups showed a gradual decrease by increasing the pH. A correlation was found between the antioxidant activity of MRPs and the volatile compounds generated at each pH. Principle component anal. clearly elucidated a distinct separation among the investigated E-HQP-xylose model mixtures based on the volatile compounds generated at different pH.
