With respect to parameters obtained from the uniaxial extension tests (Table 2), regular and optimum dough showed similar behavior to each other, while resistance to extension (Rext) was higher for control dough and extensibility was lower. The gluten dilution due to the partial substitution of WF by RS resulted in less elastic dough since the gluten network formed by the hydration of wheat proteins is the main cause of dough elastic behavior (Masi, Cavella, & Piazza, 2001). This was reflected in the reduction of E and the increased Rext. However, the effect was reverted by the enzymes, since TG and Gox promoted the crosslinking between gluten proteins. Similar results were reported by Sanchez et al. (2014) who found that Rext increased when adding RS to dough at concentrations between (1.5 and 15.5) g/100 g reaching a maximum at 9 g/100 g while the opposite effect was observed for E. Also, Ribotta, Perez, A n~on, and Le on (2010) stated that the addition of SSL, TG and HE reduced Rext and increased E in dough
