% of polyphenols released in the soluble duodenal phase (SDP) and in soluble colonic phase (SCP) upon enzymatic digestion of apple sample. Each value represents the mean of three replicates. Different letters denote a significant difference (p < 0.05 according to Tukey’s test) between cultivars within flesh, peel, and whole fruit.
