Description
Cold‑plasma surface sterilisation uses a dielectric‑barrier discharge to generate reactive oxygen species and UV photons at near‑room temperature, rapidly inactivating microbes on food surfaces without heat damage.
Technical
The plasma produces superoxide (O₂⁻), hydroxyl radicals (•OH), and ozone (O₃) along with UV photons that damage microbial DNA and proteins. The process operates at gas temperatures below 40 °C, so the product temperature remains under 15 °C, preserving sensory and nutritional quality.
