Method and apparatus for processing corn into one or more corn products including dextrose. In a preferred process, corn is processed and treated with solvent(s) to extract oil. The oil can be subsequently recovered using membrane technology. Zein may also be produced if the solvent is an alcohol. Starch in the deoiled meal is converted to dextrose by liquefaction and saccharification with enzymes. The reaction mixture containing the dextrose and other components is subjected to one or more unit operations such as screening, filtration, and/or membrane technology to produce one or more of corn gluten, soluble protein, dextrose, and fiber.
