GUDP project “UV Safe Milk” completed
GUDP project “UV Safe Milk” completed: Raslysation™ delivers proven solutions for the dairy industry
The government-funded GUDP project “UV Safe Milk” has now been successfully completed. The project team have demonstrated that Raslysation can be used as a direct, resource-efficient replacement or supplement for traditional heat treatment of milk, while maintaining food safety or product quality.
GUDP (Green Development and Demonstration Programme) is a Danish, government-funded innovation programme supporting the development and demonstration of sustainable technologies for the food, agriculture and environmental sectors. The goal is clear: to take research-based solutions all the way from the laboratory to industrial-scale application.
Full-scale validation in a commercial dairy
In December 2025, the project results were demonstrated at full scale during trials at Novelle Kaas. Here, Raslysation was implemented in a commercial dairy setting where raw milk is processed for the production of raw milk cheeses. The full-scale trials confirmed the pilot results, showing predictable microbial reductions, stable performance and consistent results without compromising product quality. A strong confirmation that the Raslysation technology can be scaled from pilot to industrial use.
Combining industrial implementation and scientific validation
The project successfully combined industrial implementation with scientific validation, with DTU Food and Lyras working closely together throughout the trials to ensure robust documentation, operational reliability and regulatory relevance.
As Nina Corydon-Petersen, Research Assistant from DTU Food put it:
“It is very rewarding to see the work you do in the lab being used at large scale to solve real problems in the dairy industry.”
Thank you to our partners
A sincere thank you to all partners involved for a strong and trusted collaboration and for contributing to the future of dairy processing. The project was carried out in close collaboration between IN-Water ApS, DTU Food, Them Andelsmejeri, Novelle Kaas, and Lyras, with valuable support from Landbrug & Fødevarer.
