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.
