Technologie alimentaire: procédés biotechnologies [ LBRAL2201C ]

Icampus

The prerequisites for this course are the basic knowledge of chemistry, biochemistry and other natural sciences as gained during the different bachelors.

No other prerequisites are needed.

Courses which are giving more details on some of the discussed topics are:

Génie des procédés : opérations unitaires [BIRC2109A]

Biochimie brassicole [LBRAL2105 ]

Chimie brassicole [BRAL2106]

Chimie des denrées alimentaires [BRAL2103]

Qualité organoleptique et microbiologique d'un aliment [BRAL2101]

The goal of this course is to give the students the understanding of the technological value added during the food and beverage production process. The course shall lead the students to combine their basic knowledge of biochemistry, microbiology as well as energetic and environmental aspects with the technological possibilities to influence the creation of high quality food and beverages with respect to production costs, legislative restrictions as well as influences on the sustainability of the product. The course will therefore use the malting and brewing processes as model process to explicitly describe the different production steps from the raw material intake till the packaged products (unit operations for separation : sorting, filtration, decantation, centrifugation, distillation,' and conservation). In further lectures the gained knowledge will be applied to explain the analogies to other food processes and their specific differences (planned: meat, dairy, distilled products, fruits/vegetables). The students will further develop in their practical work process descriptions for these industries in a seminar style.

b. Formulation spécifique pour cette activité des AA du programme

In the end of this part of the course, the student, is able to:

-       identify the conflicting priorities in food production and their impact on food products

-       analyze a process in the food industry holistically by considering all impacts on food quality, cost and the impact on the environment from raw materials till finished product

-       differentiate between different solutions for the same process step by evaluating their unique advantages and disadvantages with regards to the food production factors

-       develop own ideas for process improvements

-       transfer the learned principles to any other process in the food industry to understand and describe it

-       create a 'pilot process' in small scale out of the learned knowledge and understand its shortcomings compared to the industrial process

The evaluation of the learned content is done by the discussion and appraisal of the produced presentation and an oral or written exam

The course is based on powerpoint presentations with multimedia content (embedded movies) and completed by the presentation (and distribution for the trials) of raw materials, process aids, process equipment, and example systems.

Elearning is not explicitly included.

*parts of these lectures can be done by the students practical work / presentations.

** practical trials by the students with presentation of the used methods

Paperback of the course are available in icampus. It is recommended that the student brings them with him/her for the lessons.
