Learning outcomes This UC aims to describe the chemical composition of different classes of foods and the role of biochemistry in food production. The influence of some components of food on the human body is also analyzed.
The student, after attending this UC , should be able to:

Assess the influence that food has on the organism.
Perform different tasks in the laboratory of Food Biochemistry both in food production and the implementation of chemical analysis of foods according to European regulations.
Know the principles of food safety.
Develop the ability to search and communicate scientific information in the field of food chemistry and biochemistry.

Teaching Methodologies and Assessment Criteria The methodology used in this curricular unit is based on the definition of objectives to be achieved, attitudes, and skills to be acquired by students.
There are presential theoretical and laboratory practical classes .Teaching materials are available on the Moodle platform. Students must present orally a seminar based in a written paper on a topic related to Food Biochemistry. After the presentation, there is a discussion session on the work that aims to stimulate the student's participation in the learning process. There is a set of laboratory practical classes for the acquisition and development of analytical skills. The assessment at UC also includes 2 tests carried out throughout the semester and the practical component.
Language Portuguese. Tutorial support is available in English.
