Familiar combinations of ingredients and processing make the
structures that give food its properties. For example in ice cream,
the emulsifiers and proteins stabilize partly crystalline milk fat
as an emulsion, freezing (crystallization) of some of the water
gives the product its hardness and polysaccharide stabilizers keep
it smooth. Why different recipes work as they do is largely
governed by the rules of physical chemistry. This textbook
introduces the physical chemistry essential to understanding the
behavior of foods. Starting with the simplest model of molecules
attracting and repelling one another while being moved by the
randomizing effect of heat, the laws of thermodynamics are used to
derive important properties of foods such as flavor binding and
water activity. Most foods contain multiple phases and the same
molecular model is used to understand phase diagrams, phase
separation and the properties of surfaces. The remaining chapters
focus on the formation and properties of specific structures in
foods - crystals, polymers, dispersions and gels. Only a basic
understanding of food science is needed, and no mathematics or
chemistry beyond the introductory college courses is required. At
all stages, examples from the primary literature are used to
illustrate the text and to highlight the practical applications of
physical chemistry in food science.
