Abstract
Abstract A process for making a corn chip with potato chip texture is described. The chip has increased mouthmelt, crispness, and lightness like potato chips and it is less hard and gritty than standard corn chips. It also has a distinctive corn flavor. In a preferred process, corn is cooked in water at 140° F. (60° C.) to 212° F. (100° C.) for 30 minutes to 4 hours. The corn hulls are removed, and the corn is comminuted. A starch material is cooked in water until it is adequately hydrated, and then comminuted. The comminuted corn and starch material are mixed together to form a dough having a ratio of corn to starch material of 95:5 to 80:20. The dough is extruded, formed into a sheet, cut into segments, and deep-fried to form the finished chip.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
164 words
A process for making corn chips comprising the steps of: (a) comminuting hydrated corn having a moisture content of about 30% to about 40%; (b) separately comminuting hydrated starch material, said starch material selected from the group consisting of dehydrated potatoes, tapioca starch, corn starch and mixtures thereof; (c) mixing the corn and starch materials into a dough, the ratio of corn to starch material on a dry weight basis being from about 95:5 to about 80:20, said dough having a moisture content of about 30% to about 55%; (d) extruding the dough with a cooking extruder to provide a dough residence time in said cooking extruder of from about 5 to about 15 minutes and a dough outlet temperature of from about 180° F. to about 190° F., the starch in said hydrated corn having a high degree of gelatinization and base solubility after extrusion; (e) forming the dough into a sheet; (f) cutting the sheet into segments; and (g) deep-frying the segments.
Claim 2
Dependent Claim
