The subject builds on the lectures of Food processes and deepens undrestanding the rheological behavior of food materials. The survey of material with simple as well as with complex (viscoelastic behavior) is explained. Moreover a survey of rheometry of basic food materials is given accenting the measurement with special instruments in cereal laboratories.
