Food Physics
Physical Properties - Measurement and Applications
edited by Ludger O. Figura

Food Physics is the first textbook in this field of increasing importance for the food and cosmetics industries. It describes the principles of food physics starting with the very basics – and focuses on the needs of practitioners without omitting important basic principles.

Food Physics deals with the physical properties of food, food ingredients and their measurement.
