Production of baked snack chips with irregular shape having notched edges
Thin, baked fermented chips having an irregular shape and surface bubbles are produced by cutting a fermented, wheat-based compressed dough sheet into a plurality of pieces having different shapes and notches with a single rotary cutter so that the dough pieces form an interlocking pattern and the notches extend around the periphery of each piece. The notches are spaced around the periphery of each piece and facilitate separation of the dough pieces from each other while at least substantially avoiding tearing and breaking of the dough pieces. A plurality of notches of each piece are aligned or contiguous with notches of any adjacent piece in the interlocking pattern.
1. An array of dough pieces, the array comprising:
a plurality of dough pieces each having a periphery and being arranged in rows in an interlocking pattern wherein adjacent dough pieces are differently shaped from each other, each of the dough pieces having an irregular shape, each side or edge of each dough piece having at least one concave portion and at least one convex portion,
wherein notches are spaced around the periphery of each dough piece, a plurality of notches of each piece being aligned or contiguous with notches of an adjacent piece.
2. An array of dough pieces as claimed in claim 1 wherein at least substantially all of said concave portions have a plurality of notches, and peripheral sections between adjacent notches within each concave portion are also concave, the radius of curvature of at least substantially all peripheral concave sections between adjacent notches being at least about 0.1 inch.
3. An array of dough pieces as claimed in claim 2 wherein the notches are rectangular or square in shape and are unevenly spaced from each other around the periphery of the snack chip to accommodate different radii of curvature of said at least one concave portion and said at least one convex portion, and the weight of each dough piece is at least substantially the same.
4. An array of dough pieces as claimed in claim 1 wherein the notches are spaced around the periphery of each piece to facilitate separation of the dough pieces from each other, and at least substantially all of a plurality of notches of each piece are aligned or contiguous with notches of any adjacent piece.
5. An array of dough pieces as claimed in claim 4 wherein each side or edge of each dough piece has at least one concave portion and at least one convex portion interlocking with an adjacent dough piece, and at least substantially all of said concave portions have a plurality of notches and peripheral sections between adjacent notches, each peripheral section within each concave portion also being concave.
6. An array of dough pieces as claimed in claim 5 wherein at least substantially all of said convex portions have a plurality of notches and peripheral sections between adjacent notches, each peripheral section within each convex portion also being convex.
7. An array of dough pieces as claimed in claim 5 wherein the notches are rectangular or square in shape.
8. An array of dough pieces as claimed in claim 1 wherein adjacent dough pieces within each row are differently shaped dough pieces, adjacent dough pieces within adjacent rows are differently shaped dough pieces, and a dough piece shape is repeated within a row.
9. An array of dough pieces as claimed in claim 8 wherein a dough piece shape is repeated within a row every 4 to 7 dough pieces.
10. An array of dough pieces as claimed in claim 1 wherein the dough pieces are fermented and each dough piece has docker holes.
11. An array of dough pieces as claimed in claim 1 wherein the dough comprises:
about 30% by weight to about 80% by weight of an uncooked wheat flour, based upon the weight of the dough,
a pregelatinized waxy maize starch in an amount of from about 3% by weight to about 20% by weight, based upon the weight of the wheat flour, and
at least one potato starch.
