“…Digestion of food protein initiates in the stomach by the action of pepsin (Akimov & Bezuglov, 2012;Inglingstad et al, 2010). The mobility of pepsin into food matrices and their subsequent breakdown in the gastric environment are strongly correlated with the food matrix structure (Guo et al, 2015;Luo, Borst, Westphal, Boom, & Janssen, 2017;Nyemb, Guérin-Dubiard, et al, 2016;Thevenot, Cauty, Legland, Dupont, & Floury, 2017). Since food structure can have a critical role in determining the rate of peptide release in the stomach and absorption of amino acids/peptides in the small intestine, it is of ultimate importance to nutrition and health (Lorieau et al, 2018;Luo et al, 2017;Nyemb, Causeur, et al, 2016;Nyemb, Guérin-Dubiard, et al, 2016).…”
