In this course you will learn about the various components of milk and milk processing in the dairy. It is important to utilize as much milk as possible, and special attention will be paid to how milk can be processed and utilized in a sustainable way. This requires in-depth knowledge of the physical properties of milk and its chemical and microbiological composition. This is illustrated through various learning activities such as lectures, exercises in the lab and pilot plant, visits to the barn and group work.
The course consists of two parts:
Part 1: Milk chemistry: This section deals with the most important components of milk: proteins, fats, lactose, enzymes, minerals and selected trace elements. Emphasis is placed on structure, physical and chemical properties, as well as technological and nutritional significance, various factors that influence content and how this is in turn linked to milk quality. Functional properties of milk proteins are particularly emphasized.
Part 2: This section deals with the milk processing at the dairy with a special focus on transport, separation, homogenization, heat treatment (thermalization, pasteurization and UHT treatment), filtration and concentration of milk in order to make the best use of milk. Emphasis is placed on studying the significance of these processes on microbiology and chemical components in milk. The hygiene of the dairy is also emphasized.
- Part 1:
- Has broad knowledge of and can explain the structure and properties of various macro-nutrients (protein, lactose, fat), as well as minerals and enzymes and how the content of these components varies with different factors and affects the quality of milk.
- Has broad knowledge of and can explain functional properties of milk proteins, based on their structure and how these properties are affected by physical and chemical factors such as changes in pH and temperature.
- Can evaluate the use and suitability of different milk components (focus on proteins) to bothexisting and new innovative products.
- Can use methods to analyze functional properties of milk proteins and explain the results based on theoretical knowledge and evaluate the suitability of the various proteins in different products.
- Can find scientific literature on relevant topics in books, scientific journals and from various websites.
- Can convey central subject matter both in writing and orally and apply this in other courses including part 2 of this course.
- Understand the most important milk processing operations (transportation, separation, homogenisation, heat treatments and membrane filtration) used in milk processing, and how these processing operations influence the quality of milk products.
- Gain knowledge about composite process lines for production of consumption milk
- Gain knowledge about hygenic processing and milk microbiology.
- Be able to use knowledge about milk processing to put toghether processsing lines for milk treatment.
- Have practical knowledge about milk treatment (gained through practicals in the pilot plant of KBM).
- Be able to use practical and theoretical knowledge about milk treatment to understand which chemical, microbial and quality changes the product (focusing on consumption milk products) undergoes throughout milk processing.
Part 1:LecturesStudents work in groups that deliver written reports and give oral presentations of different topicsLab exercise with submission of lab journalSelf-study
Part 2:Lectures,practicals in the local Dairy Pilot Plant (compulsory) and journal writing (compulsory) Excursion

Part 1:The first introductory lecture and the laboratory exercise.All oral presentations of different subjects given by the students.Submission of written report and lab journal.Students must follow information given in Canvas. Students who do not attend the first lecture will not attend the course.
Part 2:Participation in 3 practicals. Submission of journal from practicals.Excursion.
Long-term assessment: Written reports and oral presentations of different subjects, as well as the lab journal per student group (40%) during the semester (A-F) and 3.5 hours written exam (60%) in the exam period / January block (A-F).
Long-term assessments and final written exam in Part 1 must be passed in order for the students to complete Part 2.
The grade obtained in Part 1 of the course counts 50% of final grade in the course.
Three journals from the practicals will be evaluated (counts 40 %).
Final oral exam (counts 60 %).
The grade obtained in part 2 counts 50 % of the final grade in this course.
To pass, all evaluations needs to be passed.
