Educational objectives
The aim of the course is to provide adequate knowledge on the importance of the relationship between food and health. The main knowledge acquired will cover the food composition, the related nutritional quality, the chemical structure of nutrients and


the structure of food constituents and the potential chemical alterations they may undergo following specific treatments, the application of analytical techniques for the quali-quantitative characterization of food products.
Students will be able to apply the acquired knowledge to assess the nutritional properties of food, which meet the recommendation for a balanced diet, able to guarantee a rational supply of nutrients. In this context, the possibility to get preliminary analytical skills will be of aid to perform quali-quantitative analyses aimed at determining the food quality.
Prerequisites
For a better understanding of the contents and to achieve the objectives of the course students must have knowledge of general chemistry, organic chemistry and biochemistry.
Teaching methods
Lectures on all topics of the course.
Other information
Course attendance is strongly recommended.
Learning verification modality
The exam consists on an oral examination lasting about 30 minutes aimed at ascertaining the actual knowledge of the subject and the level of understanding acquired by the student. Examinees have to demonstrate that they possess the knowledge, skills, and abilities required by giving complete answers to the questions on the course topics.
Extended program
Food quality and safety.
