The effects of extrusion processing on rheological and physicochemical properties of sesbania gum

Abstract The purpose of this study was to establish the effects of extrusion on rheological and physicochemical properties of sesbania gum at a constant temperature of 80 °C. Rheological data showed that both non-extruded sesbania gum and extruded sesbania gum samples exhibited a non-Newtonian pseudoplastic flow behavior. The apparent viscosity, water dispersibility and water solubility were significantly improved by extrusion processing ( p p  > 0.05) of sesbania gum with the extrusion process. The emulsion capacity and stability were enhanced ( p
