The data represent the average value ± standard deviation. a–c: different superscripts in a row indicate significant statistical differences (p < 0.05) among the four bean varieties according to one-way ANOVA followed by Tukey’s honestly significant difference (HSD) post hoc test. HCN: hydrogen cyanide; ITU: inhibited trypsin unit.
