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 phosphatidylcholine addition was 2 mg/mL, the homogenization pressure was 120 MPa, run 4 times.
