• 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.
  • Can a high-shear extrusion system extract oil from corn germ?
  • As technologies continue to advance, high-shear extrusion systems may offer a more efficient alternative for extracting oil from wet processed corn germ. Extrusion systems like the Anderson Dox? Extruder eliminate the need for separate steam heating and drying steps required in traditional stack cooking vessels.
  • 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.
  • Is corn germ hard to process?
  • But because corn germ can be notoriously tough to process, it requires the right extraction equipment to press oil efficiently to get optimal returns. Here¡¯s what you need to know about processing corn germ to capitalize on the commercial value of its oil. Whole corn kernels only contain a small amount of fat, around 5% by weight.
  • How to extract oil from corn or maize germ?
  • The main methods to extract oil from corn or maize germ: Screw pressing and solvent extraction . “Screw Oil Pressing / Expelling” is the most used in small to medium scale corn oil manufacturing process. (At present, most corn oil companies or factories use screw pressing process, the oil yield is around 70%.)
  • Is corn germ a good oil-bearing material in edible oil industry?
  • Corn germ is a good oil-bearing material in edible oil industry. With the development of corn processing industry such as starch, starch sugar and alcohol in recent years, corn germ oil has increased rapidly in the international market and has become one of the main edible vegetable oil varieties in the world.
