  • What is solvent extraction of corn germ?
  • Solvent extraction of corn germ is the process of greater industrial use because it allows the effective extraction of practically all the corn oil leaving a defatted germ meal with less than 1% residual oil.‌
  • What are the steps in chemical refining of corn oil?
  • In chemical refining, the crude or degummed corn oil is subjected to the steps of neutralization, clarification, winterization, and deodorization, for the removal of FFA, pigments, waxes, and odoriferous compounds, respectively.‌
  • What is a corn refining process?
  • It is the goal of the corn refining process to separate each component and then further refine it into specific products. Corn arrives at the refining facility by truck, barge or railcar. Refinery staff inspect arriving corn shipments and clean them twice to remove pieces of cob, dust, chaff, and foreign materials.‌
  • What is corn germ oil?
  • Most of the commercial corn oil is extracted from the germ and this is commonly known as “corn germ oil.” The germ from wet-milling operations (see Chapter 18) is recovered with up to 50% oil, which must be quickly processed because of its low microbiological and chemical stability.‌
  • What is the process of industrialization of corn oil?
  • The process of industrialization of corn oil, in general, is divided into two main stages: the extraction of crude oil which also yields a corn oil cake coproduct and the subsequent refining of the crude oil.‌
  • How is corn oil made?
  • The germs, containing about 85 percent of corn’s oil, are pumped onto screens and washed repeatedly to remove any starch left in the mixture. A combination of mechanical and solvent processes extracts the oil from the germ. The oil is then refined and filtered into finished corn oil.
