Description
Cold plasma sterilization uses non‑thermal plasma at ambient temperatures to rapidly inactivate microbes on food surfaces.
Technical
The process generates a mixture of reactive oxygen and nitrogen species (ROS/RNS), UV photons, and electric fields that damage microbial nucleic acids and cell membranes. The plasma is produced by applying a high‑voltage electric field to a gas (air, argon, or oxygen) at low or atmospheric pressure, creating ions, electrons, radicals, and excited molecules that collectively achieve high log reductions while preserving sensory quality.
