| Abstract: | The rheological properties of aqueous mixed solutions from sodium alginate and Gelatin were investigated by using a rotating rheometer. It is found that the mixed solutions behaved as non-Newtonian shear-thinning fluids. With the increase of gelatin content, the consistency coefficient of the mixed solutions increased while their viscosity behavior index decreased. Moreover, the thixtropic property of the mixed solutions was enhanced when the gelatin content increased. It is shown that such mixed solutions have a synergistic effect. |
