Abstract
Abstract An extruded, cross-cut snack food product and a method and apparatus for producing extruded, generally planar food products having ridges and valleys formed on opposite sides thereof, wherein the ridges and valleys on each side are parallel to each other, but are at an angle relative to the ridges and valleys on the opposite side. As a result, an extruded food product piece with unique texture, flavor and appearance is produced having substantial strength.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
173 words
A method of making an extruded substantially planar snack food product having a variety of texture characteristics, the product having a plurality of parallel ridges and valleys on one face and a plurality of parallel ridges and valleys on an opposite face, the parallel ridges and valleys on the two faces extending at an angle relative to each other, the method comprising: (a) extruding edible material to form a moving imperforate tubular member of said edible material, the tubular member having non-intersecting parallel ridges and valleys on the inside and outside surfaces of the tubular member formed during extrusion and during movement of the extruded tubular member to thereby produce an extruded tubular member having parallel ridges and valleys extending in a substantially helical pattern on at least one surface of the tubular member with the parallel ridges and valleys on the inside and outside surfaces extending at an angle relative to each other; and (b) forming the extruded member into a substantially planar snack food product having a variety of texture characteristics.
Claim 2
Independent Claim
173 words
A method of making an extruded substantially planar snack food product having a variety of texture characteristics, the product having a plurality of parallel ridges and valleys on one face and a plurality of parallel ridges and valleys on an opposite face, the parallel ridges and valleys on the two faces extending at an angle relative to each other, the method comprising: (a) extruding edible material to form a moving imperforate tubular member of said edible material, the tubular member having non-intersecting parallel ridges and valleys on the inside and outside surfaces of the tubular member formed during extrusion and during movement of the extruded tubular member to thereby produce an extruded tubular member having parallel ridges and valleys extending in a substantially helical pattern on at least one surface of the tubular member with the parallel ridges and valleys on the inside and outside surfaces extending at an angle relative to each other; and (b) forming the extruded member into a substantially planar snack food product having a variety of texture characteristics.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
53 words
The method of claim 2, wherein said extruded tubular member is divided into snack size pieces in steps which include first slitting the tubular member and thereafter flattening the slit, extruded member to a substantially planar form with the ridges and valleys on opposite faces extending at an angle relative to each other.
Claim 5
Dependent Claim

Claim 8
Dependent Claim
40 words
The method of claim 1, wherein the parallel ridges and valleys on one face of the extruded member are at an angle of from about 5° to about 90° relative to the parallel ridges and valleys on the opposite face.
Claim 9
Dependent Claim
40 words
The method of claim 1, wherein the parallel ridges and valleys on one face of the extruded member are at an angle of from about 30° to about 90° relative to the parallel ridges and valleys on the opposite face.
Claim 10
Dependent Claim
40 words
The method of claim 1, wherein the parallel ridges and valleys on one face of the extruded member are at an angle of from about 45° to about 90° relative to the parallel ridges and valleys on the opposite face.
Claim 11
Dependent Claim
42 words
The method of claim 1, wherein the food product produced has a thickness of from about 1/16 inch to about 3/8 inch, measured from the peak of the ridges on one face to the peak of the ridges on the opposite face.
