To obtain pasteurised potatoes, these are blanched and if desired, cooled and vacuum packaged, after an intensive peeling process, during which all irregularities are removed.

The vacuum packaged product is boiled or pasteurised in the packaging at a temperature of between 95 and 98 degrees, or sterilised at even higher temperatures. After this heating process, the packages are cooled down to a temperature of a few degrees above zero. The potato product has now been given a shelf life of between one and two months. Often, during packaging, pre-boiled or pasteurised potatoes are provided with herbs and spices, a gratin, or vegetables, to obtain a delicious dish.
