Course contents:

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 affect content and how this in turn is related to milk quality. Functional properties of milk proteins are particularly emphasized.

Part 2: Milk processing with focus on transportation, separation, homogensiastion, heat treatment (termisation, pasteurisation and UHT treatment), filtration and concentration.  

Learning outcome:
  • Part 1:

Knowledge:

  • Has a 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

Skills:

  • 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

General competence

  • Can convey central subject matter both in writing and orally and apply this in other courses including part 2 of this course

Part 2: 

Knowledge:

  • 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.

Skills:

  • 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)

General competence:

  • 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. 
Learning activities:

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).  

Teaching support:

Part 1:

Written and oral feedback on students' written and oral presentationsTeachers are available at scheduled times for guidance and discussionTeachers can be contacted via email in CANVAS

 

Part 2:

Supervision will be given at the scheduled hours for the course.

Written and oral feedback on students' written and oral presentations

Responsible for part 2: siv.skeie@nmbu.no

Syllabus:

Part 1 and 2: 

 Walstra, P., Wouters, J.T.M., Geurts, T.J., 2006: "Dairy Science and Technology". CRC, Taylor - Francis, Boca Raton, USA. (This book will is also used in the course MVI383A).

Selected articles and individual chapters from other textbooks

Prerequisites:
Knowledge of food production corresponding to MVI100, biochemistry corresponding to KJB200 and food chemistry corresponding to KJB210. Knowledge in food processing corresponding to MVI280.
Recommended prerequisites:
Food microbiology MVI220.
Mandatory activity:

Part 1:

The first introductory lecture and the laboratory exerciseAll oral presentations of different subjects given by the studentsSubmission of written reports and one lab journalStudents must follow information given in Canvas. Students who do not attend the first lecture will not attend the course.

Part 2: Participation in practicals.   

Assessment:

Part 1:

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.

Part 2:

Three journals from the practicals will be evaluated (counts 30 %).

Final oral exam (counts 70 %).

The grade obtained in part 2 counts 50 % of the final grade in this course.

To pass, all evaluations needs to be passed.

Nominal workload:

Part 1:

  • Lectures: 20 hours, student presentations: 20 hours
  • Lab exercise and journal writing: 20 hours
  • Self-study: 90 hours

Part 2: Lectures 24 h, practicals 24 h and 8 h excursion. Self-study and journal writing 94 hours.  

Entrance requirements:
