Intitulé du poste : PHD POSITION - THERMAL AND PRESSURE INDUCED PROTEIN STRUCTURING IN MEAT ANALOGUES
Ville : Grenoble
Laboratoire/Institut : ESRF/ILL
Description du poste :

Current meat production is unsustainable, depleting our natural resources while fueling climate change and consequently meat analogues are becoming increasingly popular. Meat analogues are typically produced by high moisture extrusion where protein powders are subjected to thermal and pressure treatments leading to a fiber-like microstructure mimicking the texture and appearance of meat. The project aims at in-situ studies of the formation of protein domains and their alignment that determines the mechanical properties of meat analogues. We propose to use high-pressure flow cells suitable for small angle X-ray and neutron scattering experiments to study the plastification and alignment of protein aggregates under process conditions. The experiments will allow to highlight the role of different ingredients in the structuring process. The scattering measurements will be combined with off-line characterization of meat analogues to establish a robust description of protein melt flow, structuring and product properties. Understanding protein melt properties will further impact many other fields including biomaterial-based packaging and tissue material where plastification is a key factor to control moisture permeability and mechanical strength.
