Rotary rheometer and capillary rheometer were used to study the viscoelasticity of different syrup solution. The results showed that the zero shear viscosity of the syrup solution with different water content show exponential growth rule. There is a obvious influence of different PAM content on G’ and G" of syrup solution
and the effect on G’ is more significant. With the increase of PAM content
the relaxation time and the die swell ratio (B) increased gradually
and under the same conditions
the greater the zero shear viscosity
the more obvious the elastic effect of syrup. The viscosity of syrup solution at 20~80℃ is reversible
the influence of the temperature on viscosity of syrup solution is quiet significant
and the difference of viscosity variation can be up to 1000 times.
