The superoxide anion radical scavenging activities of glucose-conjugated chicken myofibrillar proteins (Mfs), which were soluble in low-ionic-strength medium and exhibited maximum antioxidant capacity, and maltotriose-conjugated chicken Mfs, which were maximally soluble in low-ionic-strength medium, were 264 ± 45 (n = 3) and 740 ± 346 units of superoxide dismutase/g of protein (n = 4), respectively. The droplet diameters of the highest peak of o/w emulsions prepared using each conjugate as emulsifier were 8.1 ± 1.3 (n = 3) and 4.7 ± 1.9 μm (n = 3), respectively, a significant difference at p < 0.05. The emulsions prepared with glucose- and maltotriose-conjugated chicken Mfs did not show strong stability. Maltotriose-conjugate was added to an emulsion containing methyl linoleate and Tween 20 at a concentration of 0.3 % and stored at 50 °C for 7 days, resulting in significantly suppressed oil oxidation at day 5 only (p < 0.05). These results indicate that the conjugate can act as an antioxidant to inhibit oil oxidation.
