“…More recently, the influence of the gastrointestinal digestion step on the food phytochemicals contents, and on their bioactivities (mainly antioxidant capacity), have attracted special attention, which is evidenced by the great number of publications dedicated to this theme (Gumienna, Lasik, & Czarnecki, 2011;Tavares et al, 2012;Correa-Betanzo et al, 2014;Pavan, Sancho, & Pastore, 2014;Podswdek et al, 2014;Mosele, Macià, Romero, Motilva, & Rubió, 2015;Wu, Teng, Huang, Xia, & Wei, 2015;Del PinoGarcía, González-SanJosé, Rivero-Pérez, García-Lomillo, & Muñiz, 2016;Kaulmann, Legay, Schneider, Hoffmann, & Bohn, 2016;López-Barrera, Vázquez-Sánchez, Loarca-Piña, & Campos-Vega, 2016). Nonetheless, except for the recent work of Gil-Sánchez et al (2017), reports on the effects of in vitro digestion and simulated colonic fermentation processes on grape pomace phenolic compounds as well as on its bioactive properties, such as antiproliferative effects and hepatotoxicity, are lacking.…”
