Is part of:
The objective of the course is to provide students with basic and general information that can be used to understand and study the main issues of food technology principles related to food processing, sanitation and stabilisation.
1) Knowledge and understanding:
- Understand the role of water activity and the main altering events that affect food safety and stability.
- Understand the main unit operations of food technologies for food processing, sanitation and stabilisation.
- Understand the main unit operations of food technology for food processing, sanitation and stabilisation.
- Understand the role of food packaging.
- Understand the function of food labels.
- Understand the main concepts related to food shelf life.
- Know food additives and current regulations.
- Know the risks and dangers, with reference to the HACCP system.
2) Applied knowledge and understanding: ability to apply the knowledge acquired to different case studies relating to real foods.
3) Independent judgement: know how to critically rework information in order to formulate appropriate conclusions.
4) Communication skills: ability to report the results of group or individual work orally in a concise manner.
5) Learning skills: ability to critically use the concepts learned during the lessons.
