UV Radiation and Cold Plasma for Product Disinfection
Romak Export Terminal's Use of Cold Plasma to Eliminate Contaminants in Food Products
Cold plasma is referred to as "cold" because its temperature is close to room temperature. Unlike hot plasma, cold plasma does not contain thermally active ions. It consists of high-energy electrons, very low-energy ions, gaseous atoms, reactive gas species, and UV photons. As a modern non-thermal food processing technology, cold plasma uses the properties of activated gases to eliminate contaminants such as microorganisms found in food products, including meat, poultry, fruits, and vegetables. This highly flexible technology uses electricity and a carrier gas (such as oxygen, nitrogen, or helium) to disinfect food products through UV radiation and the chemical properties of the cold plasma ionization process.
Cold Plasma Increases the Shelf Life of Fruits and Vegetables
The penetration depth of plasma into materials ranges from a fraction of a millimeter to a maximum of 2&ndash;3 millimeters, depending on the surface characteristics of the material. The primary cause of spoilage and early deterioration in fruits and vegetables is the presence of microorganisms on their surfaces. It can be stated with confidence that cold plasma effectively destroys all surface microorganisms on fruits and vegetables, including bacteria, fungi, their spores, and even pests such as aphids.
UV photons damage the outer surface of microorganisms by creating microscopic pores. Reactive gas species, particularly oxygen, interact with DNA at the molecular level, altering its structure and function. These combined actions ultimately destroy the microorganisms. As a result, the primary causes of spoilage are removed from the surface of fruits and vegetables, significantly extending their shelf life.
