An apparatus for co-extruding a liquid around a periphery of a stream of meat as the meat is extruded into a casing includes a collar, a tube end connected within the collar, and a co-axial stuffing tube having a proximal end connected to the tube end. The stuffing tube has concentric inner and outer layers and a longitudinal channel between the inner and outer layers extending from the proximal end of the stuffing tube to a distal end of the stuffing tube. A liquid inlet port in the collar is in fluid communication with the longitudinal channel. Methods include co-extruding the liquid from the longitudinal channel at a distal end of the stuffing tube as the stream of meat is extruded from within the inner layer of the stuffing tube such that the liquid and the meat are not combined until both are extruded into a casing.
