Enzymatic cross-linking chemical modification and ultrasound to improve the structural and functional properties of soy protein isolate.
Soy protein isolate (SPI) is widely used as a plant protein ingredient. This study modified SPI by ultrasound-assisted laccase treatment (U + La; 150, 300, 450, and 600 W), evaluated its functional properties, and further analyzed the related physicochemical and structural changes. SPI treated with 300 W ultrasound and...
