Influences of methylcellulose on dynamic rheological behaviors of 50 g L−1 (dilute) wheat gliadins in 50% (v/v) aqueous propanol were investigated as a function of methylcellulose concentration C ranging from 5 to 20 g L−1. The mixture solutions exhibit shear rate thinning that becomes pronounced with increasing C. Specific viscosities of the first and the second Newtonian plateau viscosities, as well as the steady-flow viscosity as a function of C, reveal that methylcellulose is in the semi-dilute unentangled regime at temperatures from 5 to 65 °C. The intermolecular interaction between methylcellulose and gliadins provides high flow resistance, improved shear thinning and steady-flow activation energy of the mixture solution in comparison with pure gliadins solution.
