The disclosure relates to methods for operating a pasteurizing device for pasteurizing foods filled into sealed containers. The foods are treated in treatment zones by applying a tempered, aqueous treatment liquid to an exterior of the containers. The treatment liquid is re-supplied to at least one treatment zone for reuse via circulation circuit pipes of a circulation circuit. A partial flow of the treatment liquid is continuously removed from the circulation circuit and filtered by means of a membrane filtration means. Furthermore, a biocide is apportioned to the treatment liquid as process chemical, such that a concentration of the biocide does not exceed 0.4 mmol/L. In addition, a pH-regulating agent comprising at least one inorganic or organic acid is apportioned to the treatment liquid as process chemical, such that a pH value of the treatment liquid is set to a range from 3.5 to 7.0.

Method for operating a pasteurization apparatus

A method and a device for treating food and/or containers for holding food treats the food and/or containers in at least one treatment zone by a process liquid, wherein the process liquid is at least partially recirculated into the treatment zone or the treatment zones after completed treatment of the food and/or the containers. During continuous treatment at least some or all of the process liquid is used per time unit to form at least one stream of the process liquid, the formed stream is filtered by at least one membrane filtration system, and a filtered stream is at least partially fed back into an element holding and/or conducting the process liquid and/or into a treatment zone.
