摘要： Rheological properties influence the velocity gradient in the die passage of the extruder and the formation of fibrous structure of plant protein. The rheological properties of 11 s-rich (11 s-RI) and 7 s-rich (7 s-RI) soy protein fractions prepared at a pilot scale were studied to explore their potential in the production of extruded textured proteins. The results showed that compared to 7 s-RI, 11 s-RI exhibited larger particle sizes, lower solubility, lower water holding capacity of insoluble protein, and lower net surface charge in aqueous solutions. The ion strength enhancement with the presence of phosphate resulted in increasing solubility of 11 s-RI, and rising particles sizes in 11 s-RI and 7 s-RI solutions characterized by D4,3. But salt addition reduced the viscosity in both protein solutions when their solid concentration rose to 16 % (11 s-RI) and 45 % (7 s-RI). It's concluded solventization and salting-out were the dominant effects of the decreasing viscosity in 11 s-RI and 7 s-RI phosphate solutions, respectively.
