  • What is corn germ oil?
  • Corn germ oil is a by-product of the corn oil milling process. Most corn that is harvested is used as feed but the proportion of the corn that is milled is increasing because of bioethanol production. During the wet milling process, the germ is isolated from the starch using cyclone separators, washed, and dried.
  • What is corn oil extraction plant?
  • Corn oil extraction plant extracts corn germ from corn and produces corn germ oil by solvent extraction method. The corn oil production line includes corn germ extraction process, corn germ pretreatment and prepressing process, corn germ cake solvent extraction process and crude corn germ oil refining process.
  • How is corn germ extracted from starch?
  • During the wet milling process, the germ is isolated from the starch using cyclone separators, washed, and dried. The dried germ contains about 50% oil, in which the oil constitutes about 85% of the total amount of oil present in the corn. The oil is produced by first expelling the germ and then extracting the expeller cake with n -hexane.
  • What are the two streams derived from germ cake & hexane?
  • Two streams result from the process: a stream consisting of the mixture of germ cake, hexane, and residual oil and other known as miscela, which is the mixture of the oil with hexane. The solvent from both streams is recovered and reused.
  • Where does corn oil come from?
  • Most commercial corn oil is obtained from corn germ that is a by-product of the wet milling industry (Moreau, 2002; 2005). The wet milling process was developed in the late 1800s to optimize the production of corn starch from corn kernels.
  • What is maize germ meal?
  • Like other maize by-products, maize germ meal tends to be poor in lysine (about 4% of the protein), though richer than maize grain (3%). Maize germ meal from wet milling is relatively close to corn gluten feed but contains more protein, more oil, less fibre and about the same amount of starch and is, therefore, of higher nutritional value.
