Abstract: Multi-veined chewing gum is produced by injecting a plurality of different liquid flavor/dye compositions into a substantially homogeneous gum base composition or into a laminated or coextruded gum composition. The injection may be performed while the gum composition is being conveyed in one or more extruder head barrels, the injection being at a plurality of radial and/or circumferential positions in the barrel. In embodiments of the invention substantially straight longitudinal veins of color are then partially mixed to partially displace the colored veins in a direction transverse to the direction of extrusion so as to create veined, multi-colored patterns substantially throughout a cross section of the product in a manner so that the multi-colored patterns in the cross-section differ along the length of the extrudate. The extrudate is cut to obtain gum pieces having different veins of injected liquid additives which provide a swirled or marbleized pattern in the opposing cut ends.
