Towards a sustainable milk production

Maybe the Nordic and Baltic milk production is a little bit more sustainable now compared to a year ago? That is what the participants in the NKJ network hope for after one year of network activities.

Nordic and Baltic researchers have been networking for a year within the frames of the NKJ network  to increase the knowledge about native cattle breeds milk and reindeer milk. This research could give new opportunities in the Nordic and Baltic dairy sectors and be of help in product development.


The networking gives advantages in creating synergies between research groups and coordinating resources in an effective way.  It is also important in giving young researchers possibilities to train and work interdisciplinary.

One practical example of the advantages of the networking, is that milk samples have been exchanged between countries and institutions. Milk samples from native Swedish cattle breeds have been exchanged between Lund University in Sweden and AU Food in Denmark for analyses of protein composition using LC-MS to generate research data on native cattle breeds.

Important travelling

M.Sc. Tora Asledottir from NMBU in Norway visited AU Food, Denmark, in January and March 2016. The exchange of research data and mobility of Tora Asledottir involved experiments regarding digestability patterns of beta-casein A1 and A2 variants with human gastric enzymes and detection of peptide fragments, caseinomorhins 7 in both variants. The visit involved analyses of flourescamine, peptidomics, SDS-PAGE and protein content. The visit also gave a good chance to discuss the data and paper writing.

Another exchange of brains and data was the visit of the PhD-student Kajsa Nilsson from Lund University in Sweden at NMBU, Norway, in December 2017. The visit involved experiments regarding rennetinduced coagulation phases of coagulating and non-coagulating milk from the Swedish Red breed. It also involved protein profiling of para-κ-casein and genetic variants of caseins and whey proteins using capillary electrophoresis as well as zeta-potential measurements. Analyses, discussion and paper writing was done too.


Workshops, meetings and a PhD course have been arranged by the network. A major outcome has been to promote advanced research and research training for PhD students and young researchers in the region through various organized activities. The network has improved transfer of scientifically based information on dairy technology and food for health science to the industry and established new research collaborations in the Nordic-Baltic region, which is of great importance for future research within the research field of dairy and health.

To facilitate future research exchanges and mobility after the end of the network, a portfolio of research techniques and methodologies have been established between all the network partners.
