Abstract: Method for making a room temperature storage stable meat-containing solid pet food having a moisture content within the intermediate moisture range and simulating in appearance and texture marbelized lean red meat in chunk form which is prepared by the co-extrusion and blending of a first ingredient phase simulating lean meat and a second ingredient phase simulating fat.

Abstract: A room temperature storage stable meat-containing solid pet food having a moisture content within the intermediate moisture range and simulating in appearance and texture marbleized lean red meat in chunk form prepared by a process which comprises co-extruding a first ingredient phase simulating lean meat and a second ingredient phase simulating fat into and through an enclosed blending compartment having oriented therein a plurality of stationary elements which cut, divide and axially rotate substantial portions of the first and second ingredient phases and simultaneously maintaining a pressure within the blending compartment from about 250 to 400 psig sufficient to bind the phases together and to form a casting of randomly blended first and second ingredient phases; heat setting the casting of blended ingredient phases to form a structurally stable material; and subdividing and shaping the heat set casting of blended phases into small pieces resembling small cuts of lean meat marbled with fat.
