Sausage casing

Sausage casing, also known as sausage skin or simply casing, is the material that encloses the filling of a sausage. Casings can be made from a variety of materials, including natural animal intestines, synthetic materials, and even plant-based substances. The choice of casing can significantly affect the texture, flavor, and appearance of the finished sausage.

History

The use of sausage casings dates back to ancient times, when people first began to domesticate animals and process their meat. The earliest sausage casings were made from the intestines of slaughtered animals, a practice that continues to this day in traditional sausage making. With the advent of modern food processing technology, synthetic casings made from materials such as collagen, cellulose, and plastic have become increasingly common.

Types of Sausage Casings

There are three main types of sausage casings: natural, artificial, and reconstituted collagen.

Natural Casings

Natural casings are made from the intestines or stomachs of various animals, including pigs, cows, and sheep. They are prized for their unique, slightly irregular appearance and their ability to absorb smoke and other flavors during cooking.

Artificial Casings

Artificial casings, also known as synthetic casings, are made from a variety of materials, including cellulose, plastic, and even seaweed. They are often used for mass-produced sausages due to their uniform size and shape, and their lower cost compared to natural casings.

Reconstituted Collagen Casings

Reconstituted collagen casings are made from collagen that has been extracted from the hides of animals, then processed and extruded into a tube shape. They are a popular choice for many types of sausages due to their strength, flexibility, and uniformity.

Selection and Use

The selection of a sausage casing depends on the type of sausage being made, the desired texture and flavor, and the cooking method. Natural casings are often preferred for traditional sausages and those that will be smoked or cured. Artificial casings are typically used for sausages that will be cooked quickly or that require a uniform size and shape. Reconstituted collagen casings are a versatile choice that can be used for a wide range of sausages.
