Interactions of blueberry anthocyanins with whey protein isolate and bovine serum protein: Color stability, antioxidant activity, in vitro simulation, and protein functionality

The interaction of proteins with anthocyanins (ACNs) gives rise to significant improvements in their functional properties. To explore the interactions between whey protein isolate (WPI)/bovine serum albumin (BSA) and blueberry ACNs, light (5000 Lux, 7 days), heat (85 °C, 2 h), sucrose (0.25 mg/mL), and vitamin C (0.15 mg/mL) were used to accelerate the degradation of ACNs. Through the observation of color changes and variations in the free...
