Grape byproducts are rich sources of polyphenols with powerful antioxidant and health-promoting effects. The impact supplementing chicken diets grape on plasma thigh meat concentrations phenolic metabolites was evaluated by analyzing samples high-performance liquid chromatography quadrupole time flight mass spectrometry. Chickens were fed three experimental diets: Control diet, Control+8% pomace, Control+0.1% seed extract. In plasma, 32 identified, some which conjugated catechin/epicatechin exclusively identified in chickens enriched byproducts. Also, these showed significantly higher plasmatic 21 metabolites. meat, 14 but no differences found between diets. Higher tocopherol when byproducts, while changes observed meat. Thus, leads to a significant increase the circulation tocopherol.
