Dairy Product Technology 2

Course content

The course deals with the following areas:

Cheese and fermented milk technology: milk treatment, characterisation of cheese and fermented milk varieties and legislation, gross composition of cheese and fermented milks and their relation to dairy technology. Main cheese types such as Cottage, Soft, Feta, Continental, Pasta Filata, Cheddar, Emmenthal and Grana. Low-fat and low-salt cheese. Fermented milk products such as yoghurt, butter milk and skyr.

Cheese and fermented milk production: Acidification and glycolysis, lipolysis and esterolysis, proteolysis, peptidolysis, amino acid release, amino acid catabolism and flavour formation, roles of starter, adjunct and non-starter bacteria, ripening enzymes. Chemical methods to evaluate cheese proteolysis and aroma and flavour formation.

Fermented milk products: rheological aspects, exopolysaccharide producing dairy cultures. 

Cheese structure: Milk coagulation, syneresis and formation of cheese structure, cheese rheology, and packaging.

MSc Programme in Food Science and Technology

Learning outcome

The aim of the course is to give students a detailed knowledge of both theoretical and practical aspects of cheese and fermented milk production, characterisation, technology and biochemistry. The course also aims to equip the student for the modern dairy industry, and to think in an innovative fashion and to address the challenges faced in such an environment.


Knowledge

  • Understand chemistry, biochemistry, microbiology, physics and technology in the production of cheese and fermented milks.
  • Understand the characteristics of, and basic differences between, cheese groups and varieties.
  • Understand the use and application of dairy enzymes in cheese and fermented milks. 


Skills

  • Apply obtained knowledge of cheese and fermented milk production for the development of new cheese and fermented milk varieties
  • Apply critical analysis of cheese and fermented milk quality and characteristics. Particular focus on product defects and their cause.


Competences

  • Ability to use and evaluate scientific information and knowledge concerning cheese and fermented milks, incl. all steps of production, ripening, and packaging.
  • Ability to comprehend the technology behind different cheese varieties and fermented milk types.
  • Capacity to critically evaluate laboratory results and pilot plant trials with regard to the possible development of innovative cheese and fermented milks and/or processes.

The course involves lectures and laboratory practicals, workshops and oral presentations, literature studies, patent searches and report writing. The student must obtain their own laboratory results and evaluate them in relation to theory given at lectures and found in literature, including critical use of electronic data bases and internet. Results from all students' practicals and literature studies will be merged during oral presentations and discussions in workshops.

Type of assessment
Oral examination, 30 min
3 weeks before the examination, all examination questions (covering the essential issues dealt with in the course) will be published on Absalon. The students are expected to use all of these questions to be fully prepared for the subsequent oral exam. At the oral exam itself, two of the questions will be drawn by the student, and the examination immediately proceeds. For the first question drawn, all aids are allowed during the exam (15 minutes examination period). For the second question drawn, no aids are allowed during the exam (15 minutes examination period).
Aid

Special note regarding oral exam:

  • First question drawn: ALL AIDS are allowed for answering (15 minute duration) of the first examination question drawn.
  • Second question drawn: NO AIDS are allowed for answering (15 minute duration) of the second examination question drawn.
