A theoretical foundation is provided in this paper to study the exploitation and application of soybean protein. The results show that after urea denaturation the soybean protein solution was a typical pseudoplastic fluid while before it was a Bingham character fluid. The viscosity of both decreased with shear rates and increased with urea contents. The change was much obvious at the urea concentration of 4 mol L^{-1} ∼ 6 mol L^{-1}. After urea denaturation, the non-Newtonian index of soybean protein solution increased from 0.17 to 0.3 ∼ 0.4 at 20°C, which was still fairly low. The stabitily of fluids was pretty bad. The viscosity dropped with temperature significantly.}, issn = {2617-8699}, doi = {https://doi.org/10.3993/jfbi12200903}, url = {http://global-sci.org/intro/article_detail/jfbi/4999.html} }
