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.

A method for preparing a substantially pasteurized and/or sterilized food product; the method, which can be used to produce pasta sauces or soups, comprises: a cooking step, during which a base of the food product is obtained by thermally treating a first component at a temperature exceeding 30° C.; a mixing step, during which said base and a second, substantially solid component are mixed together so as to obtain a mixture; and an ohmic treatment step, during which said mixture is subjected to an ohmic treatment so as to obtain the substantially pasteurized and/or sterilized food product.

The present invention relates to methods for preparing liquid nutritional compositions, including liquid nutritional compositions comprising one or more proteins such as milk proteins, the liquid nutritional compositions themselves, and to methods for using such liquid nutritional compositions.

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. At least one actual value of a concentration of at least one chemical substance contained in the treatment liquid and/or of at least one process chemical added and/or of at least one internal standard added is detected by means of at least one concentration measurement sensor at at least one measurement point. A concentration, in the treatment liquid, of the at least one contained chemical substance and/or of the at least one process chemical added is manipulated on the basis of a detected actual value.

The present invention relates to a system for processing milk, which comprises a thermal pasteurization device and an autoclaving treatment device. The raw milk is sequentially subjected to thermal pasteurization and autoclaving treatment to obtain milk which can be transported by a long distance. The present invention has the beneficial effects that the method for processing milk of the present invention is used for extending the service life of the pure milk and improving the storage capacity thereof; the short service life reduces the influence on the nutrient composition and flavor of the milk; the obtained milk has a taste closer to the fresh raw milk, and the storage time is longer; after thawing to restore the liquid state, the shelf life can be up to 21 days; the milk processed by the method of the present invention can be used for transporting by a long distance.
