Abstract: The present invention relates to a system (1) for process monitoring of the treatment of media (3), in particular a HACCP-compliant system (1) for the preservation of foods. In order to ensure and standardize successful treatment, system (1) comprises an electroporator (2) for treating a medium (3) with a pulsed electric field, at least one measuring device (4) for determining a change of a condition parameter of the medium (3) caused by the treatment with the pulsed electric field, and an evaluation device (5) for comparing the determined change of the condition parameter to a predetermined change target value and for outputting a warning signal once the difference between the determined change and the predetermined change target value exceeds a limit value.

Abstract: The present invention relates to a method for processing plant leaves, in particular in the context of producing a fermented product, and to a method for producing a fermented product from plucked plant leaves, comprising the steps: optionally withering the plant leaves, optionally rolling the plant leaves, optionally fermenting the plant leaves, and drying the plant leaves. In order to reduce the expenditure in costs, time and energy of conventional methods for processing plant leaves and for producing a fermented product from plucked plant leaves, respectively, it is provided according to the invention that the plant leaves are conditioned by applying an electric field.
