| 752-2314-00L | Physics of Food Colloids | W+ | 3 KP | 2V | P. A. Fischer, R. Mezzenga | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Kurzbeschreibung | In Physics of Food Colloids the principles of colloid science will applied to the aggregation of food materials based on proteins, polysaccharides, and emulsifiers. Mixtures of such raw material determine the appearance and performance of our daily food. In a number of examples, colloidal laws are linked to food science and the manufacturing and processing of food. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Lernziel | The aggregation of food material determines the appearance and performance of complex food system as well as nutritional aspects. The underlying colloidal laws reflect the structure of the individual raw material (length scale, time scale, and interacting forces). Once these concepts are appreciated the aggregation of most food systems falls into recognizable patterns that can be used to modify and structure exiting food or to design new products. The application and use of these concepts are discussed in light of common food production. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Inhalt | Lectures include interfacial tension (4h), protein aggregation in bulk and interfaces (4h), Pickering emulsions (2h), gels (2h), aggregation of complex mixtures (4h), and the use of light scattering in investigation complex food structures (8h).

| Kurzbeschreibung | A “cook-and look” approach to process design is no longer applicable in the current environmental, nutritional and competitive constraints. The modern R&D chemical/food engineer should have a clear focus on the desired structure that needs to be achieved to design a process line or a processing equipment, coupled with in depth knowledge of the processed materials. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Lernziel | The objective of this course is to highlight the intimate links between human physiology and product sensory and nutritional functions. To optimize these functions, an understanding of the physiological functions that interact and encode the actions of those product structures must be well understood.
