The student must be able to use and understand the need of additives. General knowlgement in the production and control of the major product lines in food industry: bakery products, beverages, dairy products, fats and oils, meat, fish and poultry.
To have general knowledge in the production and control of the major product lines in food industry: bakery products, beverages, dairy products, fats and oils, meat, fish and poultry;
Planning and structuring the practical work to be undertaken in foods;
Personal autonomy in the laboratory;
Capacity for searching bibliography;
Capacity of scientific writing;
Capacity for oral presentations.
In this UC, it will be studied some aspects of the production and quality control of the following products: 1 – Food additives. 2 – Dairy products. 3 - Cereals and bakery products. 4 – Fats and oils. 5 – Alcoholic and non-beverages 6 – Meat, poultry and eggs. It is also discussed the following aspects of the Food Industry: 1 – Unit operations in food processing 2 – Food safety: HACCP and CIP. In all subjects, there is an introduction in order to point out the need of understanding chemistry, biochemistry and microbiology in production, control and development of new products with quality and safety. PW1 -Leavening agents. PW2- Hydrophilic/lipophilic balance of emulsifiers PW3 - Food colors. PW4 - Bleaching treatments. PW6 - Antioxidants/ synergists. TP7 - Antioxidant assessment. TP8+TP9– Oral presentation 1. Chocolate 2. Fish 3. Coffee 4. Cold 5. Ice-cream 6. Eggs TP10 +TP11 - Visit to one food industry. Report.
In all subjects, there is an introduction concerning the chemistry of foods and ingredients as well as their relationship with the stability, in order to point out the need of understanding chemistry, biochemistry and microbiology in production, control and development of new products with quality and safety. It is also given a special attention to our traditional food stuffs and to our integration in the European Market.
Since the industrial equipment used in the various unit operations is quite different from that used in the laboratory, it is made the collection of images and videos on the internet and on several visits performed by the teacher to food industries that are provided to students during classes, making easier to understand the various processes that occur in food industry. During practical sessions students are faced with some of the problems that occur in Industry: Choosing an emulsifier, verifying the effectiveness of an antioxidant, how long do I need to bleach a vegetable, detection of artificial colorings in food, what mixture of leavening poweders to use. These practical problems allow the practical application of knowledge obtained in the theoretical classes and thus the consolidation of the subjects learned.

Type of evaluation: Avaliação distribuída com exame final
Practical grade (PG) is obtained by a distributed assessment in practical classes together with the practical report's grades being:
PG = 0,4 Presentation/monography + 0,4 report's grades + 0,2 individual assessment in practical classes.
Final grade (FG) will be given by: FG = [0.70 x Final exam grade (FEG)] + (0.3 x PG) being FEG >9,5 and PG > 9,5.
