  • What is corn germ?
  • Corn germ is a substantial byproduct of the wet milling and alcohol industry of corn. Corn germ (dry) contains 35–56 % oil, with linoleic acid (C18:2) being the predominant fatty acid (49–61.9 %) and the highest level of tocopherol and phytosterol amongst all vegetable oils, which is a cost-effective resource for healthy nutritious oil.
  • How is corn germ oil produced?
  • Currently, commercial corn germ oil is produced by pressing and/or hexane extraction (Moreau and Hicks 2005 ), in which oil is obtained from conditioned (heated) germs, followed by mechanically expelled (‘pre-pressed’) and then hexane extraction (Moreau 2011 ).
  • Where did dry corn germ come from?
  • Dry corn germ was purchased from Xing Mao Corn Development Co. Ltd., Shandong Province, China. The raw material (dry corn germ) contained 6–7 % ( w /w, wet basis) moisture content, 16 % ( w /w, wet basis) crude protein and about 37 % ( w /w, wet basis) crude oil.
  • What ethanol is used to treat corn germ?
  • The highest yield of 93.74 % was obtained when ground steam-exploded corn germ (1.3 MPa, 30 s, 30–35 μm particle size) was treated with 30 % ( v /v) aqueous ethanol for 2 h, at 60 °C and pH 9.0. The residual oil content in water and sediment phase decreased dramatically to 4 % and 3 %, respectively.
