Course program
The course includes a general part, a specialised part, and an in-depth section. In the general part, introductory concepts related to the chemical composition of food and food safety are covered. The importance of a proper diet for personal well-being and the existence of disorders linked to the intake of specific nutrients are also emphasised. The specialised part deals instead with certain foods, highlighting their chemical composition, potential health benefits provided by specific components, and the analyses carried out to ensure authenticity and quality. The organisation within the various thematic units of the course is deeply interconnected, as discussing foods in the specialised part will refer back to their chemical composition, health properties, or issues related to their consumption described in the general part. In accordance with the depth of study requested by students in class, a division of the various topics into the following approximate hours is planned: point 1 = 24 hours (3 CFU); point 2 = 16 hours (2 CFU); point 3 = 8 hours (1 CFU).

DEEPENING– 1 CFU
Current topics (e.g., novel foods, emerging contaminants in food, organic/biodynamic/GM products) within the scope of food chemistry agreed upon with the students, who, with the knowledge and skills acquired, will be able to deepen their understanding and develop a critical reading. The aprofundamenti will actively involve students through the preparation of presentations.

Exam mode
The actual achievement of the expected learning outcomes by the student, in accordance with the educational objectives, is evaluated through an oral examination. Among the aspects contributing to the final judgment, in addition to the student's specific preparation on the exam topics, their reasoning ability based on the study they conducted independently is also assessed, which should not rely solely on memorisation skills. The duration of the oral exam is challenging to define precisely and essentially depends on the level of preparation and the student's related presentation skills. An average duration of about 20 minutes is considered possible. The teaching, as established by the Manifesto, does not include intermediate assessments but only assessments at the end of the teaching period. These assessments are scheduled in advance, communicated annually to the Administrative Offices, and published via Infostud. The student also has the opportunity for a kind of "self-assessment" during the course, as dedicated moments for review and questions on the covered concepts are held during the lessons. To pass the exam, a grade of at least 18/30 must be achieved. The student must demonstrate sufficient knowledge of both general and specific topics and be able to provide helpful information concerning food composition, its beneficial effects, and any potential side effects. To achieve a score of 30/30 with honour, the student must instead demonstrate excellent knowledge of all topics covered during the course and be able to link them logically and coherently.
