Inactivation of food pathogens using low-pressure air plasma

18 December 2014

Low-pressure glow discharge plasma was used for surface decontamination of common food packaging materials: glass, polyethylene, polypropylene, nylon, and paper foil. Compared to plasma-unexposed surfaces, no significant changes in optical properties, color characteristics, surface temperatures, tensile strengths, and deformation strains were observed with plasma-exposed surfaces.
On plasma exposure of food pathogens-loaded packaging materials surfaces 99.99% reduction in viable cell counts of tested food pathogens was observed within 5 min. Low-pressure air plasma was shown to be effective for inactivation of major foodborne pathogens (Food Control, 20 November 2014).
