Response surface methodology (with central composite rotatable design) was used to investigate the physical properties of extruded kodo-defatted soy flour-water chestnut blends in a Brabender single screw extruder. The effect of extrusion operating parameters mainly moisture content in blend, barrel temperature, die head temperature, screw speed and blend ratio on quality of extruded products were determined. The properties of product were evaluated on the basis of moisture content of extrudates (MCE), sectional expansion index (SEI), bulk density (BD) and water absorption index (WAI). CCRD based prediction model were developed by CCRD base optimization to relate the product responses to process variable as well as to obtain the response surface plots.
