Abstract
An efficient process for recovering high quality corn oil from corn germ. The process involves pre-treating corn germ by Rehydration, conditioning and, optionally flaking. This is followed by extrusion, which is the core operation in the preparation of corn germ for corn oil recovery. Water is provided up front in the process, prior to extrusion. Providing water up front reduces generation of fines and improves friction within the extruder, thereby allowing the material to move along and improving overall efficiency and streamlining of the process. The oil released from corn germ by this process is of high quality and high yield.
