Once ingested, the antioxidants contained in these seasonings mayexert protective effects against oxidative stress along the gastrointestinal tract. This fact was evaluatedby submitting the different seasonings under study to simulated digestion followed by assessing thereducing and antiradical capacities of the digested fractions. Enzymatic gastrointestinal digestionenhanced 2–3 times both antioxidant activities and colonic fermentation increased more than 10-foldthe radical scavenging ability of digested fractions compared with undigested seasonings. Digested fractionsderived from the seedless wine pomace seasoning presented generally the highest antioxidantproperties. The results were evaluated considering bioaccessibility factors to have a more realistic overviewof the potential antioxidant capacities of the seasonings and of the probable beneficial effects oftheir consumption on the prevention of oxidative damage along the gut PB Elsevier SN 0308-8146 YR 2016 FD 2016-11 LK http://hdl.handle.net/10259/4298 UL http://hdl.handle.net/10259/4298 LA eng NO Autonomous Government of Castilla y León through the researchproject BU282U13 DS Repositorio Institucional de la Universidad de Burgos RD 23-nov-2024
