Food Colloids
Interactions, Microstructure and Processing
edited by Eric Dickinson

Food Colloids: Interactions, Microstructure and Processing describes the principles and practice underlying the formulation of food emulsions, dispersions, gels, and foams. Emphasis is on understanding how the functional properties of biopolymers and surfactants determine the texture and shelf-life of multiphase food materials.

Food Colloids: Interactions, Microstructure and Processing provides essential new findings on specific topics including:

  • the interfacial rheological properties of proteins
  • the use of microscopy and image analysis to probe structure and phase transitions
  • the control of colloidal stability during thermal and mechanical processing
  • the interactions of proteins with polysaccharides and emulsifiers
  • the incorporation of neutraceuticals into food colloids
  • the consumer perception of taste and texture

Food Colloids: Interactions, Microstructure and Processing provides a link between current research on the fundamental physical chemistry of colloidal systems and the requirements of the food technologist to use modern colloid science in new product formulation.
