Demonstrating the Potential of Industrial Scale In-Package Atmospheric Cold Plasma for Decontamination of Cherry Tomatoes

Increasing process complexity and consumer demands for less processed goods has led to strong demand for new effective decontamination methods. Therefore, atmospheric tial for diverse decontamination applications. The aim of this work was to investigate the anof food products after packaging. The approach was tested under both static and continuous modes of treatment against pathogenic microorganisms Escherichia coli and Listeria innocua impact of treatment on produce quality during extended shelf life was also evaluated. Greater than 5 log reductions of E. coli population density surface attached on tomatoes was achieved in 150 s of treatment generated during either static or continuous operational mode. L. innocua be achieved in tandem with quality retention using a pilot scale system in which the mode of operation was optimized for cherry tomato as a representative fresh product.
