Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
74 words
forcing said mixture under pressure by means of a screw-type extruder through a relatively small orifice so as to raise the temperature of said mixture prior to said extrusion to above about 100*C and to cook said mixture by the combination of the developed pressure and shearing action in said extruder, and upon said extrusion to cause vaporization of said absorbed moisture to puff and expand the extrudate to several times its previous volume.
Claim 2
Dependent Claim
47 words
The process of claim 1 wherein the particle size of the starch material is such that it will pass through a 2 1/2 -mesh sieve screen having 0.315 inch openings but less than 50 percent thereof will pass through a 140-mesh sieve screen having 0.0041 inch openings.
Claim 3
Dependent Claim
18 words
The process of claim 2 wherein the starch material has an abrasion rating of less than 20 percent.
Claim 4
Dependent Claim
30 words
The process of claim 1 wherein said puffed extrudate is dried to a moisture content of less than 5 percent and a vegetable oil is applied to said dried extrudate.
Claim 5
Dependent Claim
14 words
The process of claim 1 wherein the oleaginous material is a hydrogenated vegetable oil.
Claim 6
Dependent Claim
13 words
The process of claim 1 wherein the starch material is an acid-modified starch.
Claim 7
Dependent Claim
13 words
The process of claim 1 wherein the starch material is derived from corn.
Claim 8
Dependent Claim
14 words
The process of claim 1 wherein the starch material is derived from white milo.
Claim 9
Dependent Claim
22 words
The process of claim 1 wherein the starch material and oleaginous material additionally contains a substantial proportion of dehulled and degerminated corn.
