Figure 3.

Solubility of β-conglycinin exposed to hydroxyl radical-generating systems with increasing concentrations of H₂O₂ for 3 h at room temperature. Columns with different letters (a–e) are significantly different (p < 0.05), which was concluded by SPSS software. In statistical analysis process, the effect of random error can be compared by probability value (p). If p < 0.05, it means that the effect of random error could be ignored and the difference of the columns in the Figure 3 are significative. Otherwise, columns with same letters are not significantly different (p > 0.05). All data analysed in this figure are included in the supplementary information files.
