752-3103-00LFood Rheology IW+3 KP2VP. A. Fischer
KurzbeschreibungRheology is the science of flow and deformation of matter such as polymers, dispersions (emulsions, foams, suspensions), and colloidal systems. The fluid dynamical basis, measuring techniques (rheometry), and the flow properties of different fluids (Newtonian, non-Newtonian, viscoelastic) are introduced and discussed.
LernzielThe course provides an introduction on the link between flow and structural properties of flowing material. Rheometrical techniques and appropriate measuring protocols for the characterization of complex fluids will be discussed. The concept of rheological constitutive equations and the application to different material classes are established.
InhaltLectures will be given on general introduction (4h), fluid dynamics (2h), complex flow behavior (4h), influence of temperature (2h), rheometers (4h), rheological tests (6h) and structure and rheology of complex fluids (4h).
SkriptNotes will be handed out during the lectures.

752-2003-00LSelected Topics in Food TechnologyW+3 KP2VR. Stadler, R. Behringer
KurzbeschreibungPart 1 of the course deals with global market trends, food technologies, food health benefits. Physical and chemical fundamental knowledge help grasp the molecular composition of food. Part 2 entails management of risks across the food supply chain. The focus is on technological solutions to mitigate hazards, as well as their management upstream.
LernzielThe objectives of the course are for students to understand the key drivers (market and consumer trends, health benefits, sustainability, etc.) that impact innovation in a food business environment. The course also illustrates food safety and quality considerations across the whole supply chain, using concrete examples and how certain technologies assist in reducing or eliminating food safety risks.
752-2314-00LPhysics of Food ColloidsW+3 KP2VP. A. Fischer, R. Mezzenga
KurzbeschreibungIn 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.
LernzielThe 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.
InhaltLectures 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). Most chapters include some hand-ons examples of the gain knowledge to common food products.

401-0649-00LApplied Statistical RegressionW+5 KP2V + 1UM. Dettling
KurzbeschreibungThis course offers a practically oriented introduction into regression modeling methods. The basic concepts and some mathematical background are included, with the emphasis lying in learning "good practice" that can be applied in every student's own projects and daily work life. A special focus will be laid in the use of the statistical software package R for regression analysis.
LernzielThe students acquire advanced practical skills in linear regression analysis and are also familiar with its extensions to generalized linear modeling.
InhaltThe course starts with the basics of linear modeling, and then proceeds to parameter estimation, tests, confidence intervals, residual analysis, model choice, and prediction. More rarely touched but practically relevant topics that will be covered include variable transformations, multicollinearity problems and model interpretation, as well as general modeling strategies.

The last third of the course is dedicated to an introduction to generalized linear models: this includes the generalized additive model, logistic regression for binary response variables, binomial regression for grouped data and poisson regression for count data.

752-3105-00LPhysiology Guided Food Structure and Process DesignW3 KP2VE. J. Windhab, B. Le Révérend, T. Wooster
KurzbeschreibungA “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.
LernzielThe 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.

Therefore the objective of this course is for students to be equipped with a skill set that will encompass basic digestion and sensory physiology knowledge and food structures.

The students will be exposed to this interplay all along the GI tract, including taste, aroma and texture perception, swallowing mechanics and gastro intestinal digestion with an engineering or physical sciences angle.
