Research Title

Mixing, demixing, melting and aeration: thermomechanical extrusion for current and future materials

Research Description

Thermomechanical extrusion developed by the plastics industry is now a production method of choice by much of the food industry and is used for the production of foods, feeds, conversion for bioenergy and ingredient manufacture. Companies have a wealth of know-how for their products, but this tacit knowledge is severely challenged when dealing with different biomaterials. With new challenges on the horizon, especially the inclusion of proteins into carbohydrate melts, a more detailed understanding of the science behind this complex process is required.

This Ph.D. studentship will investigate the behaviour of mixed biopolymers within the extruder using model systems to understand the role of hydration, mixing and composition at high temperatures and shear regimes.
