Research Group: Extrusion of biopolymeric materials

Extrusion

Main research topics of our group can be summarized as follows:

  • Numerical simulation and modeling of biopolymeric material flow
  • Rheological characterization of biopolymeric material flow
  • Analysis of dispersive and distributive mixing during extrusion processing
  • Measurement of thermal stress profile during extrusion
  • Functionalization of plant and milk proteins
  • Analysis of the structuring mechanisms of meat analogs
  • Structuring of ready-to-eat protein based matrices
  • Functionalization of lignocellulosic materials
  • Up-cycling of food by-products
  • Analysis of the structuring mechanism of directly expanded foods
  • Process intensification

 

Extruders have evolved from simple forming devices and become very sophisticated in the last decade. Extrusion is commonly defined as a continuous thermomechanical process relying on combination of multiple unit operations such as the transport, mixing, shearing, plasticizing, melting, cooking, polymerization, and fragmentation.

Recent trends in food extrusion technology and research have been mainly directed to the development of sustainable and functional foods, which address the increased consumer awareness of the role of food products and processes on environment, health, and well–being. Extrusion technology offers the flexibility to process a wide range of raw materials to desired product characteristics and functional properties. However, although the history of food extrusion processing goes back to the late-1800s, the control of this process and design of new extruded products are still mostly based on empirical knowledge.

In our research group, we work on developing an approach and tools which may practically enable the food research to analyze the extrusion processing at a mechanistic level and characterize the decisive process parameters crucial for complex food design and scale-up purposes. Furthermore, we use these research-tool-kits to develop strategies on delivering sustainability and functionality into complex foods and biopolymeric systems.
