Method for the destruction of microorganisms and enzymes by the combined application of heat and ultrasounds under pressure (MTS) in controlled conditions of pressure, time, temperature and sonication frequency and amplitude. The application of ultrasounds under pressure combined with the thermal processing potentiates synergically the destructing effect on microorganisms and enzymes, thus allowing to reduce the time and/or temperature of processing. The destruction rate of microorganisms and enzymes subjected to the Mano-Thermo-Sonication process follows a kinetics of reaction of first order, making it possible to calculate the sterilisation or hygienization treatments to be applied to obtain a predetermined effect. Once the Mano-Thermo-Sonication chamber has been set with the previously calculated conditions of flow velocity, temperature, pressure and sonication intensity, the product to be treated is impulsed through said chamber. |
