Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
199 words
A process for the preparation of intermediate-moisture pet food having a first ingredient phase simulating lean meat intermixed with a second ingredient phase simulating fat and shaped to resemble small cuts of marbled meat which comprises: pressure casting the first ingredient phase into elongated rectangular form and pressure casting the second ingredient phase centrally into the elongated rectangular form of the first ingredient phase; urging the combined casting of first and second ingredient phases through an enclosed blending compartment having oriented therein a plurality of stationary elements which cut, divide and axially rotate substantial portions of the casting in a manner to randomly blend the first and second phases without altering the outlying physical dimensions of the casting, and simultaneously maintaining a pressure within said blending compartment from about 250 to 400 psig sufficient to bind the phase together thereby converting the casting to that of a casting of randomly blended first and second ingredient phases; heat setting the casting of blended ingredient phases to blend the phases together and 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.
Claim 2
Dependent Claim
199 words
A process for the preparation of intermediate-moisture pet food having a first ingredient phase simulating lean meat intermixed with a second ingredient phase simulating fat and shaped to resemble small cuts of marbled meat which comprises: pressure casting the first ingredient phase into elongated rectangular form and pressure casting the second ingredient phase centrally into the elongated rectangular form of the first ingredient phase; urging the combined casting of first and second ingredient phases through an enclosed blending compartment having oriented therein a plurality of stationary elements which cut, divide and axially rotate substantial portions of the casting in a manner to randomly blend the first and second phases without altering the outlying physical dimensions of the casting, and simultaneously maintaining a pressure within said blending compartment from about 250 to 400 psig sufficient to bind the phase together thereby converting the casting to that of a casting of randomly blended first and second ingredient phases; heat setting the casting of blended ingredient phases to blend the phases together and 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.
Claim 3
Dependent Claim
27 words
Process according to claim 1, wherein the second ingredient phase is pressure cast in elongated, circular cross-section form into the rectangular form of the first ingredient phase.
Claim 4
Dependent Claim
33 words
A process according to claim 1, wherein the first ingredient phase and the second ingredient phase are maintained at a temperature in the range of about 40° to 100° C. during pressure casting.
Claim 5
Dependent Claim
32 words
A process according to claim 1, wherein the ratio of the first ingredient phase to the second ingredient phase is in the range of about 10:1 to about 2:1 respectively by weight.
Claim 6
Dependent Claim
28 words
A process according to claim 1, wherein during random blending and heat setting the first and second ingredient phases are maintained at a temperature of about 35°-75° C.
Claim 7
Dependent Claim
19 words
A process according to claim 1, wherein the first and second ingredient phases are cooked prior to pressure casting.
Claim 8
Dependent Claim
35 words
A process according to claim 1, the first ingredient phase contains a major proportion of beef by-products and soya meal, and the second ingredient phase contains a major proportion of scalded tripe and soya meal.
