摘要:
Molecular modification has emerged as a promising strategy to enhance the functional properties of food proteins. In this study, rosmarinic acid (RA) was successfully conjugated to whey protein isolate (WPI) through a radical-mediated grafting approach, achieving a conjugation efficiency of 60.23 mg/g protein (WPI-RA 0.1). Electrophoretic analysis confirmed the formation of high-molecular-weight conjugates, while comprehensive spectroscopic characterization (FTIR, fluorescence spectroscopy, and UV absorption) revealed significant structural reo...
