The objectives were to (1) determine the effects of sucrose, glucose, sodium chloride and soy soluble carbohydrate on flow characteristics of suspensions of polymers, and (2) investigate the relationship between these effects and the quantity of water associated with polymer and solute in the suspension. Polymers were defatted soy flour, soybean sodium proteinate and soybean cell wall material. A strong linear relationship was developed between the ratio of polymer and polymer bound water to solute and solute bound water (P/S) and flow characteristics. The models developed from these relationships held for soy flours containing both polymer and solute. Suspensions with high P/S showed a high degree of pseudoplastic behavior.
