Food technology
5.00 credits
52.5 h
Kather Axel; Stenuit Benoît (coordinator);
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]
Main themes
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.
Learning outcomes

At the end of this learning unit, the student is able to :

1 a. Contribution de l'activité au référentiel AA (AA du programme)
1.1, 1.2, 1.4, 1.5
2.1, 2.2, 2.4
4.1, 4.2, 4.6
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

Teaching methods
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.
Evaluation methods
The evaluation of the learned content is done by the discussion and appraisal of the produced presentation and an oral or written exam
Online resources
Les PowerPoint du cours sont accessibles sur Moodle. Il est recommandé aux étudiants de les emporter avec eux lors des présentations orales
