1. A method of producing alcohol for human consumption and/or industrial use from the recovery and treatment of nejayote obtained from a nixtamalization process or alkaline cooking, comprising: —bringing water to the boiling point; —adding a compound that raises the pH in a range from 11 to 12.50 to a cooking pot to generate an alkaline solution; —placing corn or other grain in a cooking pot; —cooking the corn for approximately 30 minutes; —letting the corn rest for approximately 12 hours; —rinsing the corn or grain with clean water for a total of approximately 3 hours, trying to remove as much as possible the remains of the alkaline solution, nejayote; —adding a chemical compound to the nejayote in order to adjust the pH to about 6; —adding nixtamalized corn flour to the adjusted nejayote; —hydrolyzing the adjusted nejayote with hydrolytic enzymes until obtaining a must, wherein the hydrolytic enzymes are favorable for the liquefaction of starch and the hydrolysis of alpha-D-(1,4) glycosidic bonds, respectively; —fermenting the must with a yeast capable of withstanding an environment with an alcohol content; and—distilling the must.
