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.
Claims18
A dyed edible food casing produced by the process which comprises:
- a. applying an edible dye to an edible carrier therefor in finely divided form so that the dye coats the carrier particles,
- b. fixing the dye on the carrier particles by contacting the coated carrier particles with a protein from the group consisting of gelatin, collagen and casein for complex formation whereby the dye becomes fixed on the carrier, and thereafter,
- c. admixing the carrier coated with the dye with an edible casing material to form an extrudable composition, and,
- d. extruding the resulting admixture to form the dye casing.
