Abstract: Process, and system, for sterilization of a product constituted by a non-distilled or demineralized liquid solution (3) contained in a rigid and/or flexible container (2). The process provides for at least one step of heating via capacitive supply of high-frequency current, with electrodes with facing surface of a closed-circuit electrode system (1) on the product, followed by a step of cooling with interruption of the supplied current; during at least part of the heating step, a counter-pressure pressure (P2) is supplied and acts inside the system (1) and on the product being treated.

Abstract: The novel sterilization process disclosed herein still relies on the sterilization action resulting from exposure of the liquids and inner surfaces of the medical article to appropriate temperatures for well-determined times, but the sterilization temperature shall be attained through generation of heat in the article itself and not through heat transfer from outside to inside. This shall be obtained through the generation of a medium to high frequency electromagnetic field, whose characteristics are precisely determined to reach the desired temperature in as little time as possible and to maintain it for the time required for safe sterilization of the article.
