Teaching methods and learning activities
The teaching of the theoretical (magisterial) fundamentals of the curricular unit is illustrated with the exhibition of slides and short videos, being complemented with visits to industrial plants and laboratory work.
The
practical lectures take place in a specific pilot unit and are conducted by
specialists from different areas, namely in the analytical control of foodstuffs and in the production of foodstuffs on an industrial scale.
During the lectures, students perform
complete microbiological tests on food and water and food contact surfaces. Afterwards, they
manufacture various products: sausages, cooked ham, alheiras, chouriço, fresh cheese, mature cheese, yoghurts, ice cream and pizzas.Evaluation Type
Distributed evaluation with final exam

Eligibility for exams
Curricular unit (UC) attendance will not be granted to students who have more than 3 (three) UNJUSTIFIED ABSENCES from practical classes.
INTRAMURAL PRACTICAL LEARNING
Practical classes lasting 4 hours are equivalent to two practical classes (2h + 2h).
After the initial ten minutes of the class, class attendance will be allowed but the minutes of delay will be recorded. When these minutes make up the duration of a class (120 min), it will be counted as one absence.
EXTRAMURAL PRACTICAL LEARNING
Admission to study visits requires signing a Term of Responsibility, in which the student complies with the rules relating to food hygiene and conduct, in accordance with the specificities of the place to be visited.
All personal electronic equipment will not be allowed inside the establishment to be visited.
If equipment is borrowed from the institution, the student will be responsible for maintaining its proper use and returning it at the end of the visit.
OBSERVATION
Students who do not obtain approval in the year of attendance of the practical lectures, do not need to attend the practical lectures again. However, students can attend the lectures and, for the purpose of theoretical examination, they must follow all the new subjects.
Calculation formula of final grade
Evaluation integrates two independent components, and the classification must be positive in both components:
A = written theoretical evaluation (75% of the final classification);
B = continuous assessment carried out during the practical classes of the curricular unit (25%). This results from the sum of the marks obtained in 3 written tests carried out in practical classes, once the main modules have been concluded, namely i) food microbiology, ii) transformation of meat products and iii) dairy products.
On the day of the written theoretical assessment (component A), each student can take the 3 tests related to the continuous assessment (component B), if:
- the student did not pass the sum of the 3 tests taken;
- by will or right, the student has not attended one of the three tests carried out during the practical classes;
- the student intends to improve the grade.
The calculation of the final grade obeys the following formula: 0.75 x A + 0.25 x B.
The approval in both components (A and B) is mandatory.
The exams (continuous evaluation) that are carried out during the practical classes correspond to the NORMAL examination period.
Special assessment (TE, DA, ...)
According to the legislation in force.
Classification improvement
Students who wish to improve the final classification will undergo a final examination at the time of application or at any other time in accordance with the legislation in force.
Observations
Learning Method: On-campus.
