Biopolymers in Food Colloids: Thermodynamics and Molecular Interactions

Maria G. Semenova, DrSci (2008) in Chemistry, Institute of Biochemical Physics of RAS, is head of the laboratory. She has published extensively on thermodynamic analysis of the impact of biopolymer interactions on structure formation in food colloids (Food Hydrocolloids, 2007, 21, 23-45) Eric Dickinson, Ph.D. (1972) in Physical Chemistry, University of Sheffield, is Professor of Food Colloids at the University of Leeds. He has published extensively on food colloids and biopolymers, including "An Introduction to Food Colloids" (Oxford University Press, 1992).
