Rheological properties of pullulan, sodium alginate and blend solutions were studied at 20°C, using steady shear and dynamic oscillatory measurements. The intrinsic viscosity of pure sodium alginate solution was 7.340dl/g, which was much higher than that of pure pullulan (0.436dl/g). Pure pullulan solution showed Newtonian behavior between 0.1 and 100s⁻¹ shear rate range. However, increasing sodium alginate concentration in pullulan–alginate blend solution led to a shear-thinning behavior. The effect of temperature on viscosities of all solutions was well-described by Arrhenius equation. Results from dynamical frequency sweep showed that pure sodium alginate and blend solutions at 4% (w/w) polymer concentration were viscoelastic liquid, whereas the pure pullulan exhibited Newtonian behavior. The mechanical properties of pure sodium alginate and pullulan–alginate mixture were analyzed using the …
