Food Additives II
Objectives
At the end of this course the student will have acquired knowledge, skills and competencies that will enable them to develop the ability of interpretation and analysis of parameters associated with processing techniques in the food industry, involving the use of additives (preservatives, antioxidants, acidifiers and acidity regulators, melting salts), further considering possible effects on human health caused by inappropriate manipulations.
In this environment students can dominate and exploit scientific bases that enable the evaluation of detailed aspects and skill acquisition with application in the development of agro-industrial productive capacity, integrating knowledge related to food security and the corresponding public health

Teaching method
The teaching, supported in the use of multimedia projections and e-learning methods (i.e., the use of the Moodle program), will include theoretical and practical classes grounded in the theoretical and application of concepts.
Evaluation method
Continuous assessment in two components: theoretical (2 individual Mini-Tests - each with 30% of the final classification) and theoretical-practical: (production and oral presentation of a research project on the synthesis and mobilization of assimilates and crop production, based on literature and laboratory studies - 40% of the final classification).
Final rating: (0.30*Mini-Test1) + (0.30*Mini-Test2) + (0.40*Research work). Approval requires a minimum score of 9.5 (scale of 20 values) for each component (theoretical-practical and theoretical).
Students without approval in the continuous assessment will be submitted to exam. Rating equal to 0.6*Exam+0.4*classification of theoretical-practical. Approval with a minimum grade of 9.5 (scale of 20 values)
Subject matter
Introductory aspects - the basic technology plan criteria, and system scale up, for the use of subclasses of food additives, according to the Portuguese and European legislation: natural and synthetic dies; Flavor enhancers (Glutamic acid and glutamates, 5''''''''-nucleotides); Emulsifiers, thickeners, gelling agents and stabilizers; transport agents; sweeteners.
