Abstract:
1. A process for the sterilisation or pasteurisation of a liquid contained in a hermetically sealed container, comprising the steps of: transporting the container into a treatment zone where the container is immersed in a flux of external transport fluid, heating a volume of the liquid to be treated in the container at a rate greater than 28° C. per second, to a treatment temperature T of between 20° C. and 66° C., agitating the container during the heating of the liquid to be treated, and depending on the value of the treatment temperature T, exposing the liquid to be treated to an electric field for treatment by electroporation immediately or slightly after heating of the liquid to be treated, the amplitude E of the electric field in V/cm being selected such that the equation: is satisfied for the values: where T is the treatment temperature in Celsius, wherein the electric field for treatment by electroporation alternates with an oscillation frequency of between 100 kHz and 1000 kHz, and is supplied in pulses, and a duration of application of each pulse of the electric field is between 10 and 100 microseconds; and wherein said process is capable of decontaminating liquids at temperatures below 66° C. in the absence of acoustic vibrations.
