  • How does wet milling work?
  • Wet milling—as primarily a food production process—relies on a traditional food-production friendly solvent-based method of extracting corn oil, which usually relies on hexane. Hexane is extremely effective in this role (capturing 90 percent of the corn oil), and relatively easy to remove from the resulting extract, leaving pure corn oil behind.
  • What is corn wet milling?
  • more than 150 years, corn refiners have been perfecting the process of separating corn into its component parts to create a myriad of value added products. The corn wet milling process separates corn into its four basic components: starch, germ, fiber, and protein. There are five basic steps to accomplish this process.
  • 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.
  • How corn oil is extracted during ethanol production?
  • In order to understand the corn oil extraction process and how corn oil is extracted during ethanol production, it helps to first understand how corn is processed. Broadly speaking, corn processing is broken up into wet milling and dry milling. Wet milling is primarily used to make food ingredients: sweeteners, starch, corn oil, and so on.
