Abstract:

Color pigments with radical-scavenging activity can be formed via Maillard reaction (MR). In the present study, four MR systems of xylose-glycine, xylose-alanine, xylose-aspartic acid and glucose-glycine were heated at 30 ℃ and 60 ℃ and their color, absorption spectral characteristics and ABTS (2,2’-azinobis-(3-ethylbenzthiazoline-6-sulfonic acid)) radical scavenging activity were assessed and compared. Xylose-glycine MR product (MRP) showed characteristic color and strong absorbance at about 570 nm and 630 nm, which was more obvious at 30 ℃ than 60 ℃. Whereas no apparent peak was observed from xylose-alanine, xylose-aspartic acid and glucose-glycine MRPs. All the four MRPs heated at 60 ℃ had higher ABTS radical scavenging activity than those at 30 ℃. The xylose-glycine and xylose-alanine MPRs prepared at both 30 ℃ and 60 ℃ had higher ABTS radical scavenging activity than other two MPRs.

Key words: Maillard reaction, color change, absorption spectrum, radical scavenging activity
