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.
