2502445 Veterinary Medicine | OB | 2 | 1 |
There are no official prerequisites, but it is recommended that the students have passed the subjects of Microbiology and Biochemistry of the first year of the Degree. Students must be able to read and understand academic texts in Catalan and Spanish.
Our health depends on what we eat daily and how we do it. Also, our economy depends on that, since the agri-food sector is one of the most active in our country. In Catalonia, there are many industries that are dedicated to the production or the processing of raw materials to convert them into food. Industries must ensure that food is safe and healthy, and that it remains appetizing for as long as possible. The administration, for its part, must carry out official controls to ensure that food legislation is accomplished. According to Order ECI/333/2008 of 13 February, which establishes the requirements for the verification of the official university degree that qualifies for the exercise of the Veterinary profession, the first competence that Veterinary graduates must have acquired is the control of the hygiene, the inspection and the technology of the production and elaboration of foods of human consumption from the primary production until the consumer. Food Science and Technology related subjects which are taught in the 2nd year of the Veterinary Degree, contribute to a part of the specific competences necessary for the exercise of the profession. In the first semester, in the subject Food Science, the students must acquire the theoretical and practical fundamentals about the characteristics, composition and alteration of foods of human consumption. In the second semester, Food Technology is studied, in which the foundations and principles of the technologies used for obtaining healthy and safe foods are acquired.
After completing the course, the students are expected to:
- Recognize the components and ingredients of foods, and their functions and properties
- Recognize the additives and their main functions
- Analyze components and their properties in specific foods
- Identify specific food quality indicators
- Relate components, properties and quality indicators
- Identify the mechanisms of food deterioration
- Evaluate the possibility and probability of deterioration of a food due to a specific cause

*Unless the requirements enforced by the health authorities demand a prioritization or reduction of these contents.
The methodology used in this subject combines the following presential and non-presential activities*:
The results of the practice evaluation test will only be taken into account for the evaluation of the subject if the student has attended to the practice or accomplished the required activities.
- in groups of 5 people, to prepare and present a case proposed by the teachers. This work involves the search and selection of information in various sources and the answer to the questions raised in the case, and its presentation and discussion in front of the teachers and other class groups.
-individual, to solve the short self-learning exercise, the tasks related to non-presential activities and to study for the exam.
The teaching material used in the subject will be available at Campus Virtual.
*The proposed teaching methodology may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

The maximum score that can be obtained is 10. The subject will be approved with a minimum overall score of 5. The evaluation will be carried out continuously during the different tasks and activities that have been scheduled.
Evaluation activities are:
- Test exam: 50% of weight in the overall score. At the end of all the training activities and on the date specified in the course schedule, the students will carry out a written test with multiple choice answers about the all the contents in the subject. Maximum score: 10 points. The minimum score needed in order to average together with the scores of the rest of evaluation activities is 5 points. In case of not passing the written exam, it can be retaken on the date in the course schedule.
- Self-learning activities, seminars and practices: 50% of weight in the overall score.
*Student’s assessment may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.
