Cold Plasma Disinfection

Cold plasma decontamination is a promising nonthermal microbial inactivation method. It involves the application of electricity to a gas, creating ions, radiation, and excited molecules that can eliminate pathogens without affecting the product.

  • Concept/Prototype

How Does It Work

  • one@2x

    The produce or container is placed in a chamber with a gas, which could be air, argon, nitrogen, oxygen, helium, or some mixture thereof.

  • two@2x

    Electricity is applied to the gas; the impact of electrons can generate reactive chemicals that will interact with and deactivate pathogens.

  • three@2x

    The application of cold plasma has a negligible effect on the product matrix, neither altering the sensory qualities of the food nor leaving any form of residue.
