Learning objectives
At the end of the course, it is expected that Students are able:
- to know and understand: a) the good agronomic practices for the management of phenotypic and genotypic variability of agricultural crops, b) the main methods of traceability and identity preservation in cereals and horticultural value chains.
- to acquire ability in: i) the application of good agricultural practices in different production chains, and in the management of molecular traceability for risk estimation, ii) the collection and interpretation of molecular traceability data obtained on both raw and transformed materials using international methods and techniques; independent judgment on the identity preservation of agri-food products.
- to distinguish vegetable fermented foods/beverages and the main microorganisms responsible for fermentation processes.
- to know how to integrate the basic acquired knowledge with bioprocesses management considering the raw materials, the microorganisms, the propagation methods (mixed and selected starter cultures) and process parameters.
- to recognize the logical steps that lead from the selection to the use of microorganisms with reference to the safety aspects using microbial cultures, including international guidelines.
- to acquire knowledge on design of bioprocesses from a vegetable raw material.
- to analyze qualitative and quantitative data of the bioprocesses.
- to communicate the acquired knowledge through written reports.

6) Selected scientific publications
Teaching methods
Teaching activities will include theoretical lessons supplemented by specialized websites and videos viewing. Lessons will also include critical reading of scientific, provided by the teacher. Student-teacher interaction will be encouraged and privileged in order to develop a critical knowledge of the topics. The slides (in PDF format) used to support teaching will be provided to students as part of the study material, lesson by lesson. They will be uploaded in the dedicated platforms. Slides are provided for studying but they cannot used / disclosed for other purposes.
Teaching tools
PowerPoint for presentations; Teams for supporting studying of specific topics and chat. Working groups on the main teaching topics.
Assessment methods and criteria
The assessment of knowledge will consist of an oral examination with questions on main topics. The critical ability to process the information and topics covered in class will be evaluated. During the oral test the ability to communicate by technical and appropriate language will be also verified.
Other information
Class attendance is not mandatory, but strongly recommended
