One of the products manufactured by German company, Wolf, is the Berner sausage. These Frankfurter-style sausages contain a portion of cheese and are wrapped in smoky bacon. The Berner is created by filling a synthetic membrane made from cellulose with sausage meat which is then smoked and cooked. A peeling machine then removes the membrane before the sausage is wrapped in smoky bacon. Although the cellulose membrane is edible and poses no health risk, its residue on the product may be mistaken for plastic or dirt, so it is essential that they cannot reach the consumer. Machine vision allows 100% inspection of the sausages.
