Interpretive Summary:

Technical Abstract: The solution rheological behavior of beta-glucan/amylodextrin blends was investigated. The effects of the blend composition and concentration were studied in small-amplitude oscillatory shear, steady-state shear, transient shear and stress relaxation experiments. The applicability of constitutive equations derived for synthetic polymers to biopolymer systems was also investigated. The K-BKZ, Giesekus, Phan-Thien Tanner and Bird-Carreau models could all fit the steady shear flow data, but only the K-BKZ and Giesekus models yielded accurate results in transient flows.
