Abstract
Food product pieces are formed with corrugations on opposite sides thereof, wherein the corrugations are substantially parallel and of substantially equal frequency and amplitude, and wherein the corrugations on one side are phase-shifted with respect to the corrugations on the opposite side by about 1/4 of the pitch distance of the corrugations. As a result, a food product piece with unique texture, flavor and appearance is produced after later cooking processes.
Claims4
An apparatus for producing slices of a food material comprising:
- (a) first and second fluted cutting blades having substantially parallel flutes of substantially identical frequency and amplitude, wherein the flutes of said first cutting blade are offset relative to the flutes of said second cutting blade by a distance substantially equal to 1/4 the pitch distance of said flutes;
- (b) means supporting said first and second cutting blades in spaced relationship and defining a cutting path for the food material;
- and
- (c) means for moving the food material in the cutting path to form cuts in the food material by the first and second cutting blades to form a slice of food material having corrugations on opposite surfaces which are phase shifted by about 1/4th the pitch distance of said corrugations.
