Study on the rheological properties of microcrystalline cellulose from soybean hulls

Effects of thickness, shearing rate, temperature, metal ion, shearing and stewing time on the rheological characteristics of microcrystalline cellulose from soybean hull were studied in this paper. Results showed that colloidal microcrystalline cellulose from soybean hulls formed gel in water and the low concentration solution (less than 2%) had the character of thixtropy. The solutions of colloidal soybean hulls microcrystalline cellulose had pseudoplastic behaviour and good thermal stability. Bivalent metal ions made the viscosity of the solutions decrease a lot and when the concentrations of bivalent metal ions rose to 0. 15mol/L or more, the pseudoplastic behavior of the solution reduced.
