Data are presented as means ± SEM. pH 2.0, pH 2.5, and pH 3 represent pH values 2, 2.5, and 3, respectively. Numbers 1, 2, and 3 represent the incubated times of 1 h, 2 h, and 3 h, respectively. SEM, standard error of the mean; ^a–e means within columns with different superscript letters are different per p < 0.05.
