HPH: high pressure homogenization, USH: ultrasonic homogenization.
Data were expressed as the mean±standard deviation of triplicate experiments.
Different capital letters indicate significant differences in the same column (p<0.05).
Different small letters indicate significant differences in the same row (p<0.05).
