Abstract
A method and a system for the application of radio frequency energy to a host material in order to inhibit the presence of pathogenic or spoilage organisms, and the host material thereby treated. In general terms, a radio frequency field is introduced to a host material, where the radio frequency field is configured to resonantly introduce thermal energy to the host material at a frequency, where the thermal energy is sufficient to cause irreversible changes in infective organisms, and where the radio frequency field is configured at a power level such that the thermal energy causes only reversible changes in the host material.
