The shear stress-shear rate data for Soy-Ogi powder suspension were obtained using Haake Rotoviscometer. The effects of concentration (10-25%) and temperature (26-98 degrees C) on the flow characteristics were considered using a number of rheological model equations. Within the temperature range considered, the relationship between Inq and 1/T is not linear. The peak eta(1/3) Viscosity is dependent on the sample concentration. The behaviour was found to be described by a modified form of the Casson model which predicted the rheology of the product. (c) 2004 Elsevier Ltd. All rights reserved.
