Characterization and quantification of tannins, flavonols, anthocyanins and matrix-bound polyphenols from jaboticaba fruit peel: A comparison between Myrciaria trunciflora and M. jaboticaba

Jaboticaba, a polyphenol-rich fruit, has numerous nutraceutical properties. Studies on jaboticaba composition have focused on solvent-extractable polyphenol compounds, whereas the matrix-bound polyphenols that can be delivered during digestion have been neglected. This study aimed to characterize the polyphenol profiling of matrix-bound and free phenolic compounds in Jaboticaba peel powder (JPP) using two fruit species, Myrciaria jaboticaba...
