The study aimed at improving the antioxidant activity ofβ-conglycinin to enhance the oxidative and physical stabilities of safflower oil-in-water emulsion stabilized byβ-conglycinin. Heating promoted binding affinity and antioxidant activity ofβ-conglycinin. Catechin and chlorogenic acid showed higher binding affinities towards unheated (or heated)β-conglycinin than caffeic acid and quercetin. The enhancement efficiencies of the phenolics on the antioxidant activity of unheated (or heated)β-conglycinin decreased in the order of catechin > quercetin > chlorogenic acid > caffeic acid. Hydrophobic force and hydrogen bonding were the important binding forces for the selected phenolics toβ-conglycinin. The complexation with catechin has no side effect on interfacial behavior and emulsifying property ofβ-conglycinin. The use of heatedβ-conglycinin-catechin complex as an emulsifier for preparing safflower oil emulsion effectively improved the oxidative and physical stabilities of the emulsion treated with lipoxygenase through inhibition of lipid oxidation, protein carbonyl formation and sulfhydryl loss.
