Technologies and Systems for Sustainable Agri-Food Processes
A.Y. 2025/2026
Learning objectives
Students will gain a solid understanding of concepts related to industrial plants, energy management, and advanced technologies applicable to food preservation, processing, and packaging. Lectures will provide a strong theoretical foundation on the principles of energy management and ecodesign in plant design, along with an in-depth exploration of modern technologies for food processing and preservation. Practical exercises (calculation-based) will enable students to apply theoretical concepts of energy efficiency, while case study analysis and group work will help develop critical thinking and problem-solving skills aimed at improving production processes in response to specific challenges.
The course content will be fundamental for students to develop the necessary competencies in innovation and quality of production processes, ensuring environmental sustainability and food safety.

Assessment methods and Criteria
The learning assessment consists of a single written exam covering all three Teaching Units (UDs)*, aimed at evaluating the student's understanding and mastery of the topics discussed during the lectures. The written exam, lasting 3 hours, will include:
- Two numerical exercises related to TU1 (maximum score for each exercise: 2.5 points)
- A questionnaire with 9 multiple-choice questions, covering the content of all three TUs (i.e., 3 questions for each TU). Each correct answer is worth 1 point; unanswered questions are worth 0 points; and each incorrect answer results in a penalty of -0.25 points. Each question will have only one correct answer.
- Five open-ended questions, designed to assess the student's acquisition of appropriate and clear technical language, argumentative rigor, and completeness in addressing a specific topic. The open questions will be distributed as follows:
TU1: one open question (maximum score: 2 points)
TU2: two open questions (maximum score for each: 3.5 points)
TU3: two open questions (maximum score for each: 3.5 points)
The final grade, expressed on a scale of thirty, will be the sum of the scores obtained in each teaching unit, with a maximum of 10 points per unit.
The exam is considered passed when the grade is equal to or higher than 18; however, a minimum score of 4 must be achieved in each TU.
Honors (cum laude) may be awarded only to exams of outstanding quality, clearly distinguished by completeness, accuracy, and rigor.
Results will be communicated via the MyAriel platform noticeboard and/or email.
Six exam sessions are scheduled annually: two during each inter-semester break and one during teaching breaks within each semester.
Students with Specific Learning Disabilities (SLDs) or disabilities are encouraged to contact the instructor via email at least 15 days before the exam date to arrange individualized measures. The email should include the respective University Services in CC:
· [email protected] (for students with SLDs)
· [email protected] (for students with disabilities).
