Learning objectives
- Knowledge and ability to understand:
At the end of the course the student will have integrated their basic knowledge on phenomena concerning the transformation of dairy and meat-based foods.
- Skills: (II Descriptor: Ability to apply knowledge and understanding)
At the end of the course the student will have developed the ability to understand the characteristics of dairy products and meat-based foods, and to hypothesize a suitable production process for the production of the main types of products
- Autonomy of judgment: (III, IV, V Dublin descriptor)
At the end of the course the student will have to possess the tools to critically evaluate the technological and microbiological aspects of dairy and meat food production.
- Communication skills: (III, IV, V Dublin descriptor)
Students should be able to present and describe the main technological processes and technological aspects for the production of dairy and meat products, as well as the characteristics of these products, using a specific language of the discipline and correct terminology.

Teaching methods
The teachings will be carried out through lectures in the classroom with the aid of slides that will represent teaching material also available online (on the Elly page of the degree course) in pdf format for students. The educational material will eventually be supplemented with articles and video material useful for understanding and deepening the topics covered. If it is not possible to hold the lessons in person, the lessons will be carried out in live streaming or recorded and uploaded on the elly platform, to guarantee students the possibility of completing the training course. Both in the case of remote and face-to-face lessons, there will be moments of confrontation with the students to clarify and fix the most important topics.
Assessment methods and criteria
In the case of the module of Innovative and sustainable technologies for dairy and meat products, the final learning test will be carried out through a single oral exam. The questions will be aimed at verifying the understanding of the salient aspects of the module, the autonomy of judgment and the ability to connect between the topics studied, the appropriateness in the use of technical-scientific language. The exam will be graded in 30th. The sufficiency threshold will be reached if the average achieved is equal to or greater than eighteen thirty.
In the case of the module of Microbiology of dairy and meat products, at the end of each part of the course there will be periodic lessons dedicated to classroom discussion with students aimed at verifying the learning status. The final assessment will be carried out through a single oral or written exam. The exam will be aimed at verifying the understanding of the salient aspects of the two modules of the integrated course.
The final outcome of the exam of the integrated course of Microbiology and technologies of dairy and meat products will be determined by the average of the marks obtained in the two different exams relating to the individual modules.
