Plasma-Based Disinfection Improves Safety in Fresh Produce Processing

SPLASH, a German government-funded research project, successfully tested Kronen’s innovative plasma washing process to improve food safety for fresh-cut lettuce.

The SPLASH project showed the efficacy of plasma-treated wash water for reducing the risk of contamination in packaged cut salads.

Ensuring the highest standards of food safety is important throughout the food and beverage industry. But that becomes even more paramount in fresh produce, where there is no kill step—no cooking or sterilization along the way—to mitigate contaminant risks. Contaminated produce has been responsible for many foodborne illnesses around the world, and the pressure is on producers to focus even more on hygiene to minimize exposure to health hazards.

In a project funded by the German Federal Ministry of Food and Agriculture (BMEL), several organizations worked together to test a newly developed Hewa washing machine from Kronen in combination with a plasma washing process in an industrial setting. Over the past 12 months, partners in the SPLASH project have been testing the washing process for fresh-cut lettuce using non-thermal plasma technology. Plasma-treated wash water (PTW) is used in a washing machine adapted for this purpose to reduce the risk of packaged cut salads being contaminated with microorganisms.
