Prefabricated steaks are produced from parts of animals not normally used for steak meat and from small animals by a process comprising: cutting muscles from the animal with the grain of the meat running parallel to the longer dimension of each strip; dicing the strips into rectangular bricks, with the grain of the meat lying parallel to the longer side of the bricks; introducing the bricks into an extruder whilst aligning the bricks with their longer axes parallel to the direction of extrusion and compacting the bricks into a solid meat log; and cutting the log transversely to form steaks wherein the grain of the meat lies along the shorter axis of each steak. For example the muscles are put through the lacerator (see drawing) and into the dicer, from which the pieces pass to the blender. The arrows show diagramatically the way in which fat and gristle and additives are added. The blended materials are passed through a pipe containing directional deflectors in the form of vanes which make sure that the strips of meat are lined up in the correct way so as to retain their grain running longitudinally. The material is forced through the extruder and after extrusion the meat is blast frozen and cut. <IMAGE> |
