The Benefits

compared to conventional methods

Graphic element Efficient energy usage

Energy Efficient

Reducing energy consumption by more than 95%, the process of cold pasteurization is both cheaper to operate and more sustainable than conventional pasteurization.

Graphic element explaining quality of product.

Higher Quality

Cold pasteurization allows for a much gentler treatment, preserving a higher level of vitamins and proteins in the product, as well as retaining the natural taste.

Global health impact

Global health impact

Cold pasteurization sets new standards for public health and safety, as it makes the treatment of liquid foods available in even the remotest locations where people do not have access to safe and properly treated foods

Graphic element explaining longer shelf life

Extended Shelf Life

Cold pasteurization has a higher bacterial kill rate and offers a more effective treatment of spores, ensuring an extended shelf life.

No fossil fuels used

No Fossil Fuels

The innovative technology behind cold pasteurization relies on electricity and eliminates any need for fossil fuels

No waste

No Waste

The non-thermal design of our cold pasteurization system ensures less use of water and ensures that no water or product is wasted during production.

Pasteurization made simple

Simpler production

The compact design of the cold pasteurization system achieves unprecedented energy efficiency, while allowing for a drastic decrease in the supporting infrastructure, including piping, heating and cooling systems etc., required by conventional pasteurization systems.

Higher up time

Higher up-time

As cold pasteurization is achieved with UV-light rather than heat, no particles burn to the surface, which occurs in conventional pasteurization equipment. Being largely self-disinfectant cold pasteurization reduces the need cleaning and frequent maintenance, ensuring a higher up-time.

Lyras' Technology

Casting new light on pasteurization

The natural anti-bacterial properties of UV-light has been known for more than 100 years and is widely used to disinfect drinking water.
Lyras’ cold pasteurization technology uses low-pressure germicidal lamps to generate this disinfecting light. UV-lamps do however omit other parts of the light spectrum which oxidizes the product and lowers the quality. As the first of its kind, Lyras’ new and patented system has integrated light filters, which remove these unnecessary and damaging wavelengths.

The light filter only allows for the desired wavelengths to pass through, which inactivates spores and bacteria in the processed liquid on a whole new level, as 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 and soda.

Curiosity led to the invention.
The positive impact on our climate and higher product quality led me to pursue the business.
