“…The addition of fiber-rich ingredients affects dough rheological properties (Table 5), depending on the addition level (Arufe et al, 2017;Bender et al, 2017;Elawad et al, 2016;Kurek, Wyrwisz, Karp, Brzeska, & Wierzbicka, 2017;Mironeasa et al, 2019a;Shiau, Wu, & Liu, 2015) and particle size Kurek, Wyrwisz, Piwińska, & Wierzbicka, 2016;Mironeasa et al, 2019c;Wang, Hou, & Dubat, 2017), the changes leading especially to the dilution effect of the main endogenous biopolymers such as starch and gluten, which give dough viscoelastic properties (Elawad et al, 2016;Shiau et al, 2015). The addition of high amounts of fibers in wheat dough can cause negative effects on final product volume, porosity, and crumb color darkening, but the addition of an appropriate proportion of soluble and insoluble fibers and/or enzymes such as hemicelluloses and pentosans can minimize these effects (Koletta, Irakli, Papageorgiou, & Skendi, 2014;Kurek et al, 2016).…”
