This study investigated the formation of conjugates between whey protein isolate (WPI) and green tea extract (GTE) using three methods: redox-pair (R), ultrasound-assisted redox-pair (RU), and ultrasonication (UL). Ultrasonication significantly reduced the reaction time for synthesizing WPI-GTE conjugates compared to the standard R method (p < 0.05). The UL methods had the highest conjugate yield determined by polyphenol binding (p < 0.05). Fourier-transform infrared spectroscopy (FTIR) and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) confirmed the conjugate formation, indicating an increased molecular weight due to protein binding with polyphenols through covalent and non-covalent bonds. Conjugates produced via ultrasonication exhibited enhanced solubility, smaller particle size, better emulsifying capacity, and improved foaming ability compared to those formed using the traditional R method (p < 0.05). However, conjugates from the R method showed higher antioxidant activity, as evidenced by DPPHand ABTS scavenging activities (p < 0.05). In conclusion, WPI-GTE conjugates created through ultrasonic treatment demonstrate potential as dual-functional ingredients, serving as both antioxidant and emulsifier.
