Course contents:

Processing of milk for different dairy products requires focus on the utilization of the entire milk raw material in a sustainable way. You will learn the technology behind the production of:

  • Fermented consumption milk products.
  • Butter 
  • Cheese and how different cheese varieties are produced as well as how they are ripened.
  • Whey products.
  • Brown whey cheese.
  • Ice cream technology.
Learning outcome:

KNOWLEDGE: Knowledge of the composition of milk in relation to the manufacturing of various products. In addition, the students shall gain good theoretical knowledge of the various processing steps and processing lines for the manufacturing of dairy products. Knowledge of the key manufacturing of important dairy products and knowledge of key factors influencing the final quality of the products are the ultimate goals of the course. More specific knowledge and understanding of the manufacturing of unfermented and fermented milk products, butter, cheese, whey products and ice cream.

SKILLS: On the basis of theoretical and practical experience, partly gained through exercises and experiments in the pilot plant for food manufacturing, the students shall understand the manufacturing processes for the most important dairy products and the quality properties of the products, and obtain skills in the production of fermented milk products, butter, cheese, whey products and ice cream.

GENERAL COMPETENCE: The course emphasises the conveyance of attitudes related to the importance of and possible uses for a food raw material such as milk, in that as much as possible of its components are used as food. This is of important in a sustainability perspective. 

Learning activities:
Lectures, exercises and laboratory analyses with an exercise and laboratory journal, group work, colloquia, excursions to milk processing enterprises and -organisations.
Teaching support:

The teachers are available during regular office hours.
