[Display omitted] • Microfluidization of soybean protein isolate-tannic acid emulsions were prepared. • SPI-TA emulsion generated at 120 MPa had the best properties. • Oxidation kinetic model of SPI and SPI-TA emulsions were established. • TA and microfluidization facilitated sustained release of curcumin from emulsions. Emulsion stability and sustained-release can be improved with a non-covalent complexing of a soybean protein isolate (SPI) with -tannic acid (TA) and dynamic high-pressure microfluidization (DHPM). The microstructure, physicochemical properties, and interfacial properties were investigated. The properties of the DHPM-treated emulsions were improved significantly, with the 120 MPa DHPM-treated SPI-TA emulsion (SPI-TA 120) having the best microstructure. The highest interface protein content, viscosity and viscoelasticity at 120 MPa of pressure facilitated the stability of the emulsion. The oxidation kinetics of emulsions was established. It was demonstrated that the oxidation stability of SPI-TA 120 was higher than SPI and SPI-TA emulsions without DHPM treatment. In addition, DHPM-treated SPI-TA emulsions showed the most positive effect on the slow release of curcumin compared to the control group. The formation of non-covalent protein complexes with polyphenols and DHPM treatment effectively increases the stability of emulsions. [ABSTRACT FROM AUTHOR]
