All samples are average value ± standard deviation (n = 3) and different letters in the same column represent a significant difference between samples (p < 0.05). Arrange all the averages in descending order, and use the letter “a” on the maximum average. The amount of soybean protein isolates (SPI) addition was 15 mg/mL, phosphatidylcholine addition was 2 mg/mL and the homogenization pressure was 120 MPa.
