Objectives and Contextualisation
Objectives and Contextualisation
The subject (materia) Food Science and Technology, which is taught in the 2nd year of the degree, provides a part of the specific competences that veterinarians must acquire during their training according to Order ECI /333/2008 which establishes the requirements for the verification of official university degrees that qualify for the exercise of the Veterinary profession. The first competence that the graduates in Veterinary Medicine must have acquired is the control of the hygiene, the inspection, and the technology of the production and elaboration of foods for human consumption, from the primary production to the consumer.
The contents of Food Science and Technology is made up of two courses. Food Science in the first semester, in which the student must acquire the knowledge, theoretical and practical, about the characteristics, composition and alteration of foodstuffs for human consumption. And Food Technology in the second semester, in which the student acquires the foundations and principles of the technologies used to obtain healthy and safe foods.

| Self study | 58 | 2.32 | 2, 4, 3 |
The methodology used in this course combines theoretical lessons and practical activities that expand and/or reinforce the knowledge acquired during theoretical lessons.
Practical sessions include laboratory practices, practices at Servei Planta Pilot de Tecnologia dels Aliments, a computer room practice and a self-learning activity that requires researching and selecting information in different resources and answering the proposed questions.
The teaching material used in the subject will be available in Moodle.
Moodle will be used as a mechanism for the exchange of information between professors and students.
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.

Assessment
Continous Assessment Activities
| Title | Weighting | Hours | ECTS | Learning Outcomes |
|---|---|---|---|---|
| Exams | 70% | 3.5 | 0.14 | 1, 2, 5, 3 |
| Online tests | 30% | 0 | 0 | 1, 2, 4, 5, 3, 6 |
Continuous assessment
The subject will be approved with a minimum overall score of 5 out of 10. The assessment will be individual and will be carried out continuously during the different training activities that are taught. The course is organized into two Units (I and II). Unit I has a weight of 40% of the final grade. Unit II has a weight of 60% of the final grade. The minimum grade for each Unit to calculate the weighted average to obtain the final grade is 5.
The grade for each Unit will be calculated as follows:
- 70% will correspond to the mark of the face-to-face exam, which will include all the theory, plant and laboratory practices, seminars and self-study activity. The exam has 2 parts: a) multiple choice questions and b) open-ended questions. The open-ended questions will not be corrected if a minimum grade of 4 out of 10 is not obtained in the multiple choice questions. A minimum mark of 5 is necessary in the exam to pass the Unit.
- 30% will correspond to the mark of the online tests in the Moodle classroom that all practical activities and self-learning have associated. Depending on the type and conditions of each practical activity, the test will be done during it or after finishing it. The closing date of the test will be announced for each activity and, once the date has passed, the test will not reopen. If the student has not attended to a practice, the value of the test grade of that practice to calculate the overall grade will be 0.
Resit
To participate in the resit, the student must have been previously assessed in a set of activities that represent a minimum of two thirds of the final grade of the subject. The resit will consist of an exam that will include questions about all the contents of the Unit that must be recovered.
To pass the subject, it is necessary to obtain a grade ≥ 5 in the resit exam corresponding to each Unit in order to average with the other Unit. To calculate the final grade, the weightof each Unit is maintained (40% Unit I and 60% Unit II).
The students will be considered not evaluable if they have participated in assessment activities that represent ≤ 15% of the final grade.
Single assessment
The subject will be approved with a minimum overall score of 5 out of 10. The subject is organized into two Units (I and II). Unit I has a weight of 40% of the final grade. Unit II has a weight of 60% of the final grade. A minimum grade of 5 is necessary in each Unit to calculate the weighted average that gives rise to the final grade.
The single assessment consists of:
- An exam that will include all the theory, plant and laboratory practices, seminars and the self-study activity of Units I and II. The exam will have 2 parts: a) multiple choice questions and b) open-ended questions. The open-ended questions will not be corrected if a minimum grade of 4 out of 10 is not obtained in the multiple choice questions. The mark of this test corresponds to 70% of the mark of the subject. A minimum mark of 5 is necessary to pass the subject.
- The mark of the tests of the practical activities (laboratory practices, plant practices, seminars and self-study activity), which corresponds to 30% of the mark of the subject. The assessment of these activities will be carried out by means of a test on the single assessment date. If the student has not attended a practical activity, the value of the test for that activity to calculate the overall grade will be 0.
The date of the single assessment will be the same that the date of the examination of Unit II of the continuous assessment.
The same resit system, the same criterion of not evaluable and the same procedure for reviewing the grades will be applied as for continuous assessment.
The students will be considered not evaluable if they have participated in evaluation activities that represent ≤ 15% of the final grade.
