Abstract
β-Lactoglobulin (β-LG) was modified and conjugated to xylobiose using the Maillard reaction. The antioxidant activity of the Maillard reaction product, β-LG-xylobiose, was measured in vitro and compared to that of conjugated β-LG-lactose. The reaction for 7 days led to conjugated β-LG-xylobiose with a relative molecular mass ranging between 19 and 22 kDa based on SDS-PAGE analysis. It is confirmed that xylobiose bound to β-LG by gas-liquid chromatography. One milligram of conjugated β-LG-xylobiose contains 108 μg of xylobiose, while the available ε-amino group content decreased to 40% after the Maillard reaction. Conjugated β-LG-xylobiose had a higher radical scavenging activity than free β-LG. As the modification by xylobiose had a higher efficiency than the modification by lactose, it is found that xylobiose is a useful oligosaccharide for protein modification. Furthermore, the radical scavenging activity of β-LG was improved by modification with xylobiose.
