Prerequisites: Organic chemistry 1, Analytical chemistry 1, Organic chemistry 2, Analytical chemistry 2
Target skills and knowledge: The course aims to provide knowledge on the chemical composition and structural characteristics of the main components present in foods with particular reference to the transformations that they undergo during cooking or industrial processes. The course also provides the knowledge on the main analytical methods for analysis of foods.
Examination methods: Written
Assessment criteria: The evaluation of the preparation of the student will be based on the level of knowledge of topics dealt during the lessons
