Who invented the sausage skin?

The invention of sausage casings, or skins, can be traced back to ancient civilizations, with the earliest known use attributed to the Sumerians around 3000 BC. They utilized animal intestines to encase meat mixtures. Over the centuries, various cultures refined this technique, but it was not until the 19th century, with advancements in food preservation and processing, that modern sausage casings, including those made from collagen and synthetic materials, became widely used.
