The food producer Paul Goop uses food-quality nitrogen and carbon dioxide (Gourmet N and Gourmet C) from Messer to package peeled jacket potatoes. In the Swiss German dialect, the product is also known as “Gschellti Gschwellti”. The gases are mixed in the desired mixing ratio at the customer’s facilities. The family business processes over 1,400 tons of potatoes per year. It is the first Swiss company to cook potatoes with the skin still on before further processing. They retain their flavor, vitamins and color better as a result. The prepared potatoes are delivered either whole or in chopped up form to wholesale customers such as restaurants, hospitals and caterers.
