Wet-milling is a process in which feed material is
steeped in water, with or without
sulfur dioxide, to soften the seed kernel in order to help separate the kernel’s various components. For example, wet-milling plants can separate a 56-pound bushel of corn into more than 31 pounds of
cornstarch (which in turn can be converted into
corn syrups or
corn ethanol), 15 pounds of
corn gluten meal for use in
animal feed, and nearly 2 pounds of
corn oil.
