A method for treating food which is in an insulating encapsulation or casing or which will be introduced into same, by means of non-conventional ohmic heating, for heating a sausage product such as scalded sausage, hot dogs or similar food products present in a casing, wherein the respective food is brought into contact with spaced electrically conductive electrodes, and the electrodes are connected to a controllable or regulatable current source,
- characterized in that
- the electrodes are each in the form of at least one first and one second electrode group, wherein the electrode groups are at a distance (AEG) to one another,
- each electrode group has a number of individual electrodes, similar to a comb-like set of needles, wherein the neighboring individual electrodes of the comb-like set of needles are each at a distance (AEE) to one another,
- furthermore, the distance (AEG) is greater than or equal to the distance (AEE), and the respective comb-like set of needles is arranged to penetrate the insulating encapsulation or the casing and to pierce it or is moved to pierce through the food in such a way that entry and exit points of the comb-like set of needles are formed in relation to the food or the encapsulation or casing.
