Conteúdo: 	The composition and bioaccessibility of grape polyphenols and minerals is influenced by grape variety and
matrix. Grape constituents may be determinant for the absorption of bioactives and are crucial for exploring
grape by-products as functional food ingredients. In this study, the peel, pulp, and seeds of Vitis labrusca L. grapes
were characterized by LC-DAD and ICP OES and changes in polyphenols, macro- and microelements were
monitored using simulated human digestion. The pulp and seeds were characterized by flavanols, and the peels
were high in phenolic acids. After the digestion, the highest bioaccessibility was found for quercetin (85%),
while anthocyanins diglucosides were more bioaccessible in the gastric phase (153% and 113% for malvidin and
cyanidin, respectively). The digestion of grape peels resulted in higher bioaccessibility of most minerals, suggesting
the nutritional value of this constituent. These changes provide a step further towards applications and
bioactive relevance of the grape parts.
