In Collagen Casing Colored With Colorings And Red #3

Collagen casings are edible casings used for sausages and other processed meats. They are made from collagen, a protein typically sourced from the hides of cows or pigs. These casings are then colored with various colorings, including synthetic dyes like Red #3, to achieve a desired appearance.

Collagen casings provide structure and shape to products like pepperoni, salami, and snack sticks, making them easier to process and consume. The added colorings, such as Red #3, are used to enhance the visual appeal of the casing, often to mimic traditional colors or differentiate products.

Collagen is generally recognized as safe by the FDA. Red #3 is a synthetic color additive that the FDA revoked for use in food in January 2025, with manufacturers having until January 2027 to comply. This revocation was based on findings that it caused cancer in male rats, though the FDA stated this is not relevant to human risk. California's Food Safety Act (AB 418) also bans Red #3 in food from 2027. JECFA has evaluated Red #3. The FDA announced a plan in April 2025 to phase out other petroleum-based synthetic dyes, but Red #3 was revoked separately and is not part of that specific phase-out plan.
