Title: Edible food casing dyed with an edible dyestuff and process for its manufacture

Abstract: A dyed edible food casing is produced by effecting dyeing prior to filling of the casing. The edible dyestuff is incorporated, as such or in encapsulated form, with the raw composition awaiting extrusion. Instead, the extruded tube is itself dyed. Water-resistance is imparted to the dyestuff by admixing a cross-linkable substance.
