Once ingested, the antioxidants contained in these seasonings may exert protective effects against oxidative stress along the gastrointestinal tract. This fact was evaluated by submitting the different seasonings under study to simulated digestion followed by assessing the reducing and antiradical capacities of the digested fractions. Enzymatic gastrointestinal digestion enhanced 2–3 times both antioxidant activities and colonic fermentation increased more than 10-fold the radical scavenging ability of digested fractions compared with undigested seasonings. Digested fractions derived from the seedless wine pomace seasoning presented generally the highest antioxidant properties. The results were evaluated considering bioaccessibility factors to have a more realistic overview of the potential antioxidant capacities of the seasonings and of the probable beneficial effects of their consumption on the prevention of oxidative damage along the gut Autonomous Government of Castilla y León through the research project BU282U13 application/pdf eng Elsevier Food Chemistry. 2016, V. 211, p. 707–714 http://dx.doi.org/10.1016/j.foodchem.2016.05.127 Attribution-NonCommercial-NoDerivatives 4.0 International http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess ABTS Antioxidant capacities Colonic microbial fermentation Enzymatic gastrointestinal digestion Folin index QUENCHER Wine pomace Seasoning Food Biochemistry Molecular biology Alimentos Bioquímica Biología molecular Total antioxidant capacity of new natural powdered seasonings after gastrointestinal and colonic digestion info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion
