Tools for the evaluation of food quality on fresh, preserved and transformed products. 3. Physical-chemical parameters of food. 4. Organolepthic properties of food. 5. Food safety: Genomics in food quality assesment, Proteomics in food quality assesment, genetically modified food. 6. Analysis of individual components: harmful compounds for food quality and food contaminants.

Practical component: Characterisation of the food quality of some food of vegetable origin and its derived products.

Teaching method

Theoretical sessions with datashow. Practical laboratorial sessions.

Evaluation method

- Continuous assessment with 3 elements of evaluation:

Evaluation of theoretical component: 2 Tests (each one 35% to the final grade). Weighted average of the 2 elements of evaluation must be equal or higher than 9.5 values (scale of 20).

Evaluation of the practical component: Presentation and discussion of one group work (20% to the final grade); 1 Test (10% to the final grade).

Final rating: (0.70*Theoretical component) + (0.30*Practical component). Approval 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: 0.70 *Exam + 0.30*Classification of the practical component. 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 practical component cannot be improved and follows in the next year.
