Simultaneous plasticization and blending of isolate soy protein with poly[(butylene succinate)-co-adipate] by one-step extrusion process

This article focuses on the preparation of isolated soy protein plasticized by a glycerol and water mixture/poly[(butylene succinate)-co-adipate] blends by an original single step extrusion process. Prepared blends were injection-molded and characterized for their molecular interaction, morphology, rheological, thermal, dynamic mechanical, and mechanical properties. The comparison of these results with those obtained using a more regular two-step compounding process validates the technical efficiency of this cost-effective one-step approach.
