Bio-Based Food Processes
A.Y. 2018/2019
Learning objectives
The course aims to familiarize students with the
integrated, interdisciplinary approach required to uitilize
the catalytic potential of enzymes and whole cells in food
bioprocesses. Food bioprocesses embrace modification of
raw materials for the production of food components,
including proteins, peptides, flavours and nutraceuticals.
Attention will be focused on the involvement of
biotechnology in food bioprocesses and on the
optimization of bioreactors for industrial applications.

Expected learning outcomes
Completion of the course will make the student able to:
develop competences on the production and the use of
biological systems (microbial cells, enzymes, proteins and
peptides) used in the food industry for the production of
ingredients, food stuff and for the valorization of by-
products; understand the impact of food
biotransformations for increasing food biological value,
shelf-life, and market value.
