A method of recovering corn coarse fiber by flotation, which features the use of a hydrocyclone, or other separating machinery, in which the specific gravity of the slurry contained therein has been increased to approximately 12-14 Baumé so that the corn coarse fiber is of a lighter density than the remainder of the slurry. Therefore, the corn coarse fiber can be separated from the remainder of the slurry because it floats to the top of the slurry. If the present pericarp recovery process is added to a modified dry-grind ethanol production line, a high value co-product (the pericarp) is added to the other co-products and the end-product of ethanol, which can all be sold, and the economic efficiency of the plant is increased. More specifically, the present invention provides a process for recovering corn coarse fiber including the steps of: soaking corn in water to loosen the attachments of various grain components therein to each other, degerminating the soaked corn to strip the corn coarse fiber and the germ away from the endosperm, recovering the germ, and recovering the corn coarse fiber by flotation.
