What are sausage casings made of?

There are two types of sausage casings – natural and artificial. The natural casing is the intestines of animals (casings), which have long been used for domestic sausages. The intestines are thoroughly washed, cleaned of internal contents and mucus. A thin white shell remains, almost transparent after filling with minced meat. It is used for expensive quality products. In the mass production of sausages, an artificial casing is used. Some types of it are made from natural materials – cellulose and collagen. The latter is edible as it is made from the middle layer of animal skins. Synthetic polyamide casing is used even more frequently. Polyamide is considered a hygienically clean material, but it contains toxic substances. When choosing which sausages to cook, give preference to sausages with natural casings.
