Learning Outcomes
The objectives of this course is to familiarize students with laboratory testing of milk and dairy products by performing microbiological and chemical analyses on real foods, obtaining and interpreting the results. In particular, upon successful attendance and examination, the student is expected to know the sampling plans for milk and dairy products according to Reg. 2073/2005, the common microbiological methods for assessing the quality of milk and dairy products, and the chemical methods for assessing the quality of milk and the evaluation of the level of heat treatment of milk.
General Competences
  • Apply knowledge in practice
  • Retrieve, analyse and synthesise data and information, with the use of necessary technologies
  • Make decisions
  • Work autonomously
  • Work in teams
  • Be critical and self-critical
