Replacing heat with UV-light created the possibility to reinvent pasteurization, we call this new method Cold Pasteurization. The natural anti-bacterial properties of UV-light has been known for more than 100 years and is widely used for disinfecting drinking and processing water, but now it can also be used for non-see through liquids such as milk, this allows for a more sustainable production.

Lyras’ Cold Pasteurization technology uses low-pressure germicidal UV-lamps to generate the disinfecting light, and as the first of its kind, Lyras’ new and patented system has integrated light filters, which remove the unnecessary wavelengths, that elsewise could risk to lower product quality. The light filter only allows for the desired wavelengths to pass through, and these inactivate spores and bacteria at a level conventional pasteurization cannot. As an addition hereto, the unique design geometry creates a turbulent flow that exposes the entire volume of the liquid. In short, you have a system that can treat any non-see-through liquid, e.g. milk, juice or soda.
