Prerequisites

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.

b.     Production systems with practical demonstration

*parts of these lectures can be done by the students practical work / presentations.
** practical trials by the students with presentation of the used methods

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

As part of this course, students are assessed in two ways:
• continuous certification assessment including a mandatory seminar to be presented at the end of the semester (grade A: 30% of the final grade)
• a written exam during the session (70% of the final mark). For this written exam, the part taught by B. Stenuit is worth 50% (grade B). The part taught by A. Kather is also worth 50% (grade C).
The final grade is the weighted average of grades A (30/100), B (35/100) and C (35/100).
