  • 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 is corn germ isolated 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.
  • 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 oil extracted?
  • In most industries, corn germ oil is extracted by pre-pressing and solvent to improve the yield of corn germ oil . Recent study demonstrated that the corn germ oil extracted by supercritical CO 2 could improve the antioxidant capacity of oil without lowering the profile of fatty acids .
  • 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.
  • What is a co-product of a corn kernel?
  • The first co-product is corn germ, which contains 40¨C50% oil (Table 3-A). The corn germ fraction from the wet milling process represents about 5% of the mass of the kernel (Moreau et al., 1999b).
