Food Quality I
Acquisition of knowledge, skills, and competences: (1) parameters of definition and evaluation of the food quality of products of plant origin, fresh, preserved and transformed; (2) nutritional quality; (3) sensorial evaluation; (4) food safety; (5) improving the quality of foods of plant origin.

Lectures with datashow or computer resources.
- Assessment with 3 elements:
Theoretical-Practical Evaluation: 2 Tests (each one 40% to the final grade). Weighted average of the 2 elements of evaluation must be equal or higher than 9.5 values (scale of 20).
Non-Theoretical-Practical Evaluation: Monographic work being performed in groups of two or three elements and discussion (20% to the final grade).
Final rating: 0.80 * Theoretical-Practical Evaluation + 0.20 * Non-Theoretical-Practical Evaluation). Approval is obtained with a minimum score of 9.5 (scale of 20).
- Students without approval on the continuous assessment examination can proceed to the final exam, with the classification being defined by: 0.80 * Exam + 0.20 * Non-Theoretical-Practical Evaluation. Approval with a minimum score of 9.5 (scale of 20).
- Improvement of the classification requires a registration in the schedule examination period. The classification of the Non-Theoretical-Practical Evaluation cannot be improved and follows in the next year.
In the Theoretical-Practical component (lectures) quality is defined in the food scope and food groups of plant origin are presented. Tools for the evaluation of food quality are described. The quality of foods of plant origin is analysed considering physical-chemical parameters and organoleptic properties. Finally, new technologies in food quality (genomics, proteomics, and genetic engineering) are presented in order to improve the quality of foods of plant origin. In the non-Theoretical-Practical component aim the development of a monographic work on a relevant topic in the food area.
