Laatu - Microbial Reduction Solution

Enhancing food integrity, traceability and sustainability through digitalisation.

What is Laatu

Laatu is a sustainable microbial reduction solution for industrial dry food processing. It offers an efficient reduction of harmful microorganisms including spores, with field trials consistently reporting 5-Log (>99.999%) reduction or more on Salmonella with minimal or no impact on quality: nutrients, taste, smell, and appearance.

Laatu does not introduce chemicals, water or radioactive sources and due to its small footprint it can be easily integrated into existing processes.

With a connection to Bühler Insights, Laatu can be used as a powerful tool in food safety auditing. Laatu is released for spices and introduction to other dry food markets is under development.

How it works

How Laatu works

Laatu features specialized and contained lamps that generate a cloud of low energy electrons. Each seed or grain free-falls into the contained area and is homogenously exposed to the electrons, inactivating pathogenic microorganisms present. This process is done in milliseconds. Due to the limited penetration depth of low energy electrons the technology offers a gentle surface treatment, preserving the quality of the core parts of the food.
