中文摘要：

研究了β－伴大豆球蛋白弱凝胶体系的稳态与动态粘弹性质。高蛋白质量分数（〉3％）的β－伴大豆球蛋白水分散液显示出一定的弱凝胺属性。此弱凝胶体系在稳态条件下呈现明显的剪切变稀现象。在小变形范围，该分散体系呈现典型的蛋白浓度相关性；在整个测定的频率范围内，储藏模量总是大于损耗模量。对Cox-Merz规则的偏离进一步表明该蛋白分散体系是一类弱凝胺体系。该凝胶的网络结构对离子强度敏感，可见静电作用力对其形成具有重要的作用。

英文摘要：

The steady flow and dynamic viscoelastic properties of a weak gel system of aqueous soy β-Conglycinin dispersions, prepared by dialyzing against distilled water at high concentration, are reported, β-Conglycinin proteins at high concentration （〉3%） showed weak gel behavior. Under steady shear flow, strong shear thinning behavior was observed. When a small deformation in the linear viscoelastic region was applied, the dispersions of the β-Conglycinin protein showed typical weak gel-like （entanglement） or semidihied polymeric solution rheological behavior depending on the concenlration： the storage modulus was always larger than the loss modulus within the entire frequency range examined. The violating of the Cox-Merz rule conformed that this system was a weak gel system. The β-Conglycinin weak gel network was susceptible to ionic strength, suggesting that electrostatic force played an important role in the formation of this weak gel network.
