Dynamic multiscale structural characterisation of Foods by SESANS
When processing raw materials to final consumer food products, their structures undergo changes at length scales from nano-, via meso- to macroscopic sizes. These multiscale architectures govern critical product functionalities as shelf life stability, water holding capacity, texture and mouth feel. To be able to rationally design food processing routes, insights in these hierarchical multiscale structures, in particular under dynamic conditions, is a prerequisite.
Small-angle neutron and X-ray scattering can quantify multiscale structures in food systems under dynamic processing conditions. We develop measurement techniques, sample environments and data-analysis methods for these studies. We are in close cooperation with food scientists from universities, food research institutes and industries.
