APhenols: Total extractable phenolics compounds as mg GAE⋅g–1 shell; BTannins: Condensed tannins as mg CE⋅g–1 shell; Canthocyanins as mg of c3g⋅g–1 shell; DORAC: Antioxidant capacity as μmolTrolox⋅g–1 kernel. Different letters in the same column indicate significant differences according to Tukey test (p ≤ 0.05). ESEM: standard error of mean; Fp-values indicate statistical probability of cultivar effect; (p ≤ 0.05; n = 3) after ANOVA test.
