  • 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.
  • How is corn bran oil extracted?
  • In addition to traditional solvent extraction (petroleum ether), the methods of hexane extraction and subcritical butane extraction were used to extract corn bran oil which contains high content of unsaturated fatty acids and phytosterols [ 144 ].
  • 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 oil produced?
  • 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.
  • Are there any patents on back-end corn oil extraction?
  • In addition to the Greenshift patents, recent U.S. patents on back-end corn oil extraction have also been issued to ICM ( Gallop et al., 2012) and Primafuels ( Woods et al., 2012 ). Several patent applications on back-end oil extraction have also been have also been submitted and published by POET ( Bootsma, 2010, 2011, 2012).
  • Is corn kernel oil a recovery germ?
  • Typically, the crude oil of corn kernel (4%) is almost stored in corn germ and the entire germ mainly contains oil (48%), protein (13%), and starch (12%). However, the recovery germ composition in oil (18%¨C41%), protein (12%¨C21%) and starch (6%¨C21%) is also influenced by growing conditions, genetic factors, and isolation methods [33 ].
