Abstract: A method for sterilizing the raw milk is provided to allow the raw milk to be sterilized at a lower temperature within a short time with the improved sterilization effect. A method for sterilizing the raw milk comprises the step of contacting the supercritical fluid with the raw milk to inactivating the microorganism contained in the raw milk; and optionally stirring the supercritical fluid with the raw milk. Preferably the supercritical fluid comprises a mixture fluid comprising supercritical carbon dioxide, supercritical nitrous oxide or their mixture.

Abstract: A method for inactivating biofilm is provided, which inactivates the biofilm in an improved disinfecting power using the supercritical fluid in a short time. A method for inactivating biofilm using the supercritical fluid comprises: a step for positioning an object in which the biofilm is formed in the surface at the high pressure container; and a step for inactivating biofilm by bringing the biofilm into contact with the supercritical fluid. The biofilm using the supercritical fluid is exposed to the supercritical fluid in the state that it is not dipped in the aqueous medium and the moisture is adhered. The supercritical fluid comprises the supercritical carbon dioxide, and the supercritical nitrous oxide or their mixture fluid.
