| CHIMICA E BIOTECNOLOGIE DELLE FERMENTAZIONI
(objectives)
The purpose of this course is to provide the student with a detailed knowledge of microbial physiology and microbial interactions during food fermentation and the importance of the correct selection of microorganisms for precise control of the fermentation processes. The course aims to introduce students to the phases necessary for the development of a fermentation process and to the aspects concerning the monitoring of fermentation processes.
Module II The course provides the knowledge of factors affecting fermentation processes, giving the ability to evaluate appropriate strategies for setting up and developing new processes. Students will acquire the proper terminology in fermentation biotechnology (communication skills). All the information acquired will be applied to several case studies, in such a way that students learn to deal with new problems inherent in bioreactor processes.
EXPECTED LEARNING RESULTS
Knowledge and understanding The results defined by this descriptor are pursued through lectures, didactic laboratories, viewing of multimedia material, and integrative seminars in teaching. The student will acquire knowledge of the use of microorganisms and fermentation techniques to produce fermented foods and beverages.
Applying Knowledge and Understanding What is defined by this descriptor is achieved through lectures, laboratories, viewing multimedia material, and written reports. The students will have to demonstrate that they apply general knowledge to specific case studies.
Autonomy of judgment The course aims to provide students with all the tools required to analyze and use experimental results and practical cases concerning the production of fermented foods and beverages to develop their critical thinking.
Communication skills The ability is developed: in the classroom, through the active involvement of the students through written reports that allow evaluating the communicative ability and the correct ownership of scientific language; outside the classroom, through direct interaction with the teacher, in person or via the web.
Learning ability The student is involved in reading technical-scientific articles and viewing multimedia videos on the themes inherent to the program's topics to stimulate the understanding of the text and the critical analysis of the content of the same.
