Collagen Casings

Collagen casings are thin, edible tubes made from collagen, a protein found in animal connective tissues like skin and bone. The collagen is extracted, purified, and then formed into a casing, often used for processed meat products. They are designed to be eaten as part of the final product.

Collagen casings are primarily used in the food industry as a casing for sausages, hot dogs, and other processed meats. They provide a uniform shape and a desirable 'snap' when bitten into, while also holding the meat mixture together during cooking and processing. Their edibility makes them a convenient alternative to non-edible casings.

Collagen casings are generally recognized as safe (GRAS) by the FDA for use in food. They are primarily composed of protein and are digestible. International bodies like JECFA have evaluated collagen and related substances, and EFSA has also reviewed collagen peptides. No significant health concerns are associated with the typical consumption of collagen casings.
