Objetivos
This UC aims to transmit knowledge about the operations and processes most used in the food and chemical industry, which allow the control of physical and chemical properties during their transformation and storage. The student must have notions about the characteristics that define the quality of these products, changes in their properties; You must know and know how to apply appropriate analytical techniques to each product under evaluation.

Programa
Theoretical Component:
1. Main Agri-food Industries.
1.1. Physicochemical properties of the main products in the food industry.
1.2. Chemical composition, modifications in processing and conservation.
2. Main Chemical Industries
2.1. Physicochemical properties of some chemical products (polymers, fuels, paints, etc.).
3. Main physical properties of foods and some chemical products.
Assessment of Density, Viscosity and Texture: Types of Rheological Behavior: Hooke's solid and Newton's liquid. Non-Newtonian Behavior and Plasticity. Viscoelasticity. Analytical methods.
Color Assessment: colorimetric and spectrophotometric methods for color determination.
Practical component:

Métodos de ensino e atividades de aprendizagem
In the theoretical classes a participatory-expository teaching methodology will be employed, as well as the debate within the group of students. In the laboratory classes students will be asked to perform several experiments of which they will have to write a report.

Fórmula de cálculo da classificação final
Continuous assessment:NF = 40% Test 1 + 10% Work 1 + 50% Work 2.
- The Test is performed individually and mandatory delivery. Minimum grade of 8 points is required in the written and individual test.
- Work 1 is a theoretical research with oral presentation. The work to be developed focuses on themes assigned by the teacher.
Work 2 are reports of various laboratory practice activities and prepared in a group of 3-4 students.
Exam (all periods):NF = 40% Exam + 10% Work 1 + 50% Work 2
Minimum grade of 8 points is required in the written and individual exam.
UC under an exception regime - 100% assessment by exam is not applicable
