  • 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.
  • 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 ].
  • What is the lipid content of corn germ?
  • With the development of the corn processing industry, oil has become one of the important products of corn deep processing. Generally, the lipid content of corn germ is about 18%¨C41%, which accounts for more than 80% of the amount of the total lipid in corn.
