The interfacial complexation between goose liver protein (GLP) and oily dispersed curcumin in impacting the protein interfacial dynamics and high internal phase emulsions (HIPEs) stabilization was validated. Results from surface hydrophobicity, size, atomic force microscopy, and fluorescence quenching showed that pre-ultrasonication (100 W, 300 W and 500 W) conduced to pronounced heterogeneous hydrophobic interaction that elevated GLP adsorption and association at the interface. The synergistic curcumin complexation with medium ultrasonication (300 W
