  • 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.
  • 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.

Global annual corn production is 700 million tonnes but corn oil production is only 400 000 tonnes.
  • How much oil is in corn?
  • Corn grains contain approximately 3%¨C5% oil. When corn is used for starch production, one of the major by-products is germ, which is characterized by a high content of oil (40%¨C50%). Corn oil (usually referred to corn germ oil) for human consumption is commonly obtained from corn germ (Shahidi, 2006 ).
