Title: Process for the production of a dyed edible food casing

Abstract: Dyed edible food casings, e.g. sausage casings, are produced by applying an edible dye to an edible carrier therefor, fixing the dye on the carrier by use of a protein, and admixing the carrier with an edible casing material to form an extrudable composition. That composition is then used for production of the casing by extrusion. The dye can be a water soluble dye, a fat soluble but water insoluble dye, or a water insoluble, alkali soluble dye.
