A method for preparing corn fiber oil. The method involves separating corn fiber from corn kernels (e.g., by a wet milling process), drying the corn fiber, grinding the dried corn fiber to produce ground corn fiber having a particle size of less than about 100 microns, combining the ground corn fiber with an aqueous solution having a specific gravity effective to float aleurone cells, removing the floating aleurone fraction, drying the aleurone fraction to form a dried aleurone fraction, grinding the dried aleurone fraction to form a ground aleurone fraction, extracting corn fiber oil from the ground aleurone fraction by a way selected from the group consisting of an organic solvent and supercritical fluid extraction, and separating the extracted corn fiber oil from the extraction medium.
Also shown is a method of recovering corn aleurone cells from corn fiber involving separating corn fiber from corn kernels by a wet milling process, drying the corn fiber, grinding the dried corn fiber to produce ground corn fiber having a particle size of less than about 100 microns, combining the ground corn fiber with an aqueous solution having a specific gravity effective to float aleurone cells, and removing the floating aleurone fraction.

Methods and apparatus for processing corn into one or more corn products. Oil is extracted from corn or corn products or by-products with a solvent. The corn-solvent mixture is separated into streams, one of which preferably includes an extract containing at least oil and solvent, and another containing de-oiled corn solids and adsorbed solvent. The solvent is separated from oil, and the de-oiled, desolventized corn solids are processed to provide one or more corn products.

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.
