Influence of in vitro gastrointestinal digestion and probiotic fermentation on the bioaccessibility of gallic acid and on the antioxidant potential of Brazilian fruit residues

This study aims to investigate the fruit residues of cashew apple and soursop regarding their chemical composition (sugars, carotenoids and organic acids by HPLC-DAD/RID), total phenolics, flavonoids, antioxidant capacities (ABTS, DPPH, FRAP and ORAC), inhibition of α-amylase enzyme, cytotoxicity by cell viability of fibroblast cells lines (L929). The aqueous and ethanolic extracts were submitted to simulated in vitro gastrointestinal digestion...
