From powder to paste: Processing food materials with low moisture content

  • Characterization of powder flowability at dynamic flow conditions relevant to industrial applications.

Adequate material properties with respect to, among others, flowability, reconstitution behaviour and aroma retention are key to ensure their processability and resulting product quality/stability of dry food materials. Whether it is for a (spray)dried powder or a milled flour, by understanding the relation between the respective production processes and resulting material properties, improved functionalities can be ensured. In our current project we combine a dynamic powder flow tester with active temperature and humidity control, to improve the understanding of powder flow at conditions relevant to industrial applications. Obtained insights will be used to provide guidelines for efficient powder handling and formulate target specifications of agglomerated powders.

  • 3Dstructuring: Structuring food products on the micron- and millimeter scale.

The flow behaviour of concentrated systems/pastes is inherently complex. This complexity, however, also provides the possibility to structure the material on both the macro- and microscale. To induce this multi-scale structuring, a special focus is put on 3D food printing, which shows great potential for individualized nutrition. In our current project we work with water-in-water emulsions, i.e. blends of two soluble polymers that phase separate, which are printed inside a fluid gel bath.
