In this paper, a rheo-optical methodology based on small angle light scattering and polarimetry is applied to investigate in-situ and on a time resolved basis the flow-induced structures in aqueous biopolymeric blends. Water-dextran-gelatin is chosen as an example. It is verified to what extent the laws and scaling rela-tions, originally developed for synthetic polymer blends, are valid for the morphology development in this aqueous biopolymeric mixture. It was observed that under low shear rate conditions, the biopolymeric emul-sion can be regarded as a conventional emulsion. However, at high shear rates flow induced homogenization occurs.
