Learning outcomes It is intended that the student should know:
- Water properties from a chemical and microbiological perspective.
- The main groups of foods, their chemical compounds, methods of analysis, and the main sources of contamination.

At the end of the Course Unit, the student should be able to:
- Understand the chemical properties of water, identify sources of pollution, and apply treatment methods.
- Use microbiological analysis methods for water and food.
- Distinguish the main components of different foods and discuss the analytical methods appropriate for food analysis.
- Identify international organizations responsible for standards applicable to the food sector.
- Explain the principles of techniques used in physical-chemical and microbiological analyses of water and food.
Syllabus Water: Water quality and public health; Chemical contaminants; Microbiological quality of water; Water contamination; Water treatment; Methods of chemical and microbiological analysis of water; Legislation.
Food Chemistry: Food and nutrition; Methods of analysis of proteins, lipids, and carbohydrates in food.
Food Microbiology: Standards and recommended methods for different types of determinations; Quality control.

Practical Work:
- Drinking water: indicator parameters (pH, Conductivity, Oxidizability, Total hardness, Turbidity)
- Olive oil analyses: acidity and spectrophotometric test;
- Determination of protein concentration in biscuits;
- Microbiological analyses of water;
- Microbiological analyses of food;
Teaching Methodologies and Assessment Criteria Face-to-face teaching delivered in 3 modules.
Final Grade (FG) = 1/3 Module 1 + 1/3 Module 2 + 1/3 Module 3 (Pass if FG = 9.50)
Each module will have:
- A theoretical component (T) with a test (80% of the grade)
- A practical component (P) (20% of the grade)
Breakdown by module:
- Module 1 (Water): grade = 80% theoretical test + 20% practical*
- Module 2 (Food): grade = 80% theoretical test + 20% practical**
- Module 3 (Microbiology): grade = 80% theoretical test + 20% practical**
* Practical: 10% presentation of practical work carried out and 10% to its discussion.
** Practical: test based on the practical work carried out.

- The practical grade in each module must be = 9.50 to obtain attendance.
- The exam grade (= 9.50 to pass) will correspond to 80% of the final grade, with the remaining 20% being the average of the practical components of each module.
- Completion of all practical activities is mandatory.
