Iceland’s largest dairy company chooses Raslysation™ – to optimize the quality of yellow cheese
Mjólkursamsalan (MS), Iceland’s largest dairy company, has invested in a raslysation system from Danish company Lyras A/S. The unit is installed at the MS dairy in Akureyri, northern Iceland, and is now operational for brine treatment in yellow cheese production. By replacing its former microfiltration system with raslysation, MS is stepping into a more efficient, streamlined and sustainable future, achieving significant operational savings through the implementation of this technology.
Efficient cleaning and significant energy savings at Lyras
The raslysation system is integrated with MS’s central CIP system, enabling reuse of cleaning fluids. This setup reduces chemical and water consumption while ensuring fast and efficient cleaning of the system.
“From now on, our brine for yellow cheese will be treated using raslysation. This results in substantial savings in energy, salt, water, and cleaning agents. The greatest benefit is the reduced chemical and energy consumption, which supports our sustainability goals. At the same time, we maintain strong microbiological control, which is essential for both food safety and product quality.” Says Kristin Halldórsdóttir, Plant Manager at MS Akureyri.
A responsible choice for the future
At Lyras, the collaboration with MS is seen as a strong signal that the future of dairy production requires both innovation and responsibility.
“MS is a forward-thinking company, and we are pleased that a raslysation system for brine treatment in yellow cheese production is now installed at MS Akureyri. With this upgrade, MS gains a system that is reliable, easy to operate, and environmentally friendly.” Says Niels Skou, Senior Sales Engineer at Lyras.
Quality at the core
The shift to raslysation supports MS’s long-term strategy of optimizing energy usage and reducing environmental impact, without compromising product quality.
“Transitioning from microfiltration to raslysation maintains our strict microbiological standards. Raslysation provides the microbiological safety we require, without compromising quality.” Emphasizes Plant Manager at MS Akureyri, Kristin Halldórsdóttir.
This is clear proof that technological innovation and food traditions can go hand in hand.

About Lyras and Raslysation™
Lyras has developed and patented the raslysation technology, which inactivates microorganisms in both transparent and opaque liquids using UV light. The system uses a UV light source combined with an optical filter to block unwanted wavelengths. Liquid is passed in a controlled flow across the light source, ensuring complete exposure. This allows effective inactivation of unwanted microorganisms.
The technology consumes significantly less energy than traditional pasteurization and filtration. With raslysation, energy savings of 60–90% and water savings of 60–80% can be achieved compared to conventional pasteurization.
