The rheological behavior of amylopectin–β-lactoglobulin–water system in the region of incompatibility was studied by performing constant shear rate and oscillatory measurements. Phase-segregated samples were prepared at concentrations that laid over the binodal and tie-lines.The results were interpreted in terms of the isostress and isostrain blending laws. For this purpose the bases of Takayanagi model was used and a modified model considering the gradual formation of double emulsions close to the phase-inversion concentration that explain the transition was proposed.Good agreement between observed and calculated values was obtained using the isostress and isostrain models.Phase segregation and the phase-inversion control the rheological properties of the amylopectin–β-lactoglobulin mixture in aqueous media.
