Food structure and rheology

Foods are recognized and liked because of their appearance, odor, the way they flow or crumble, the way they snap or melt in the mouth, release aromas, produce mouthfeel, and satisfy the body after eating. Many of these aspects are caused or influenced by the composition, structure and rheological properties of the product and these are in turn determined by ingredient choice and processing during manufacture.

The way the combination of food ingredients and processing result in the specific structure and rheological behavior of a food product is my principal field of expertise. 




Expertise on food structure and rheology:

  • emulsions and foams
  • emulsifying  properties of proteins, lipids, surfactants and their interactions
  • de-foaming by emulsions
  • absorption and interfacial properties 
  • micelles, microemulsions
  • rheology of liquids and semi solids
  • gels and emulsion-filled gels
  • fat crystallization, milk fat composition, butter, chocolate
  • dairy, cream, yoghurt, quark
  • starch, thickeners, gelling agents
  • layered dough
  • fat replacement
