Learning outcomes It is intended that the student knows:
-Properties of water from microbiological and chemical point of view.
-The main food groups, the respective chemical compounds and methods of analysis and also the main sources of contamination.


At the end of the Curriculum Unit the student should be able to:
- Understand the chemical water properties, identify sources of pollution and apply methods of treatment;
- Use methods of microbiological analysis for water and food;
- Distinguish the major components of the various foods and discuss analytical methods suitable for analysis of food;
-Refer to international bodies responsible for food industry standards.
