Represents statistical differences (P < 0.05) between 1 h and 4 h or 24 h at the same pH.
Represents statistical differences (P < 0.05) between pH 7.4 and pH 5.0 at the same time.
Data are expressed by the mean (n = 3) ± standard deviation of the mean. All data were analyzed by one-way ANOVA analysis of variance followed by Tukey’s post-test.
