The particle size (A) and absolute zeta-potential value (B) of SPI-BANs complexes. Different letters indicated the significant differences among different samples (P < 0.05). SPI, SPI-BANs-1, SPI-BANs-2, SPI-BANs-3, and SPI-BANs-4 represented the soybean protein isolates (1 mg/mL) complexed with blueberry anthocyanins at different concentrations of 0, 0.9, 1.8, 3.6, and 7.2 mg/mL, respectively
