Learning Objectives

The course aims to provide students with basic knowledge about the chemical composition of food products and the chemical composition of xenobiotics present, characteristics, interactions, reactivity, and modification reactions. It is also proposed to provide students with basic knowledge of the chemical characteristics and reactivity of toxic substances with particular reference to the classes of natural and xenobiotic compounds present in food and their interaction.


Course Structure

Frontal teaching with slides The teaching is developed e. stimulate the student's ability to learn what is stated in the course program. Single laboratory exercises
