Abstract
The present invention provides a rapid and continuous process for making corn dough masa and tortilla chips by processing non-hydrated corn feed, an alkalizing agent, and water through a cooker-extruder under certain process parameters so as to make the masa and subsequently the finished tortilla product. The corn feed can be any form of corn ranging from whole kernel corn to finely ground corn flour. The extruder process conditions use a Specific Mechanical Energy input of 300 to 550 watt hours per kilogram of material fed to the extruder; a Residence Time Distribution of from about 175 to 400 seconds; a Shear Rate of 65 to 140 reciprocal seconds; and a Peak Temperature of 230.degree. F. to 270.degree. F.
