  • 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 extracted from milled corn germ?
  • Corn germ oil was extracted from milled corn germ using diluted aqueous ethanol as solvent. Batch extractions were carried out in 500 mL glass reactor vessels which were series connected with a constant temperature water bath machine (MP-501 A, Shanghai Yiheng Scientific Instrument Co., Ltd., China).
  • 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.
  • Can aqueous ethanol extract corn germ oil?
  • This result proved the preponderance of aqueous ethanol method again. In this study, an efficient and eco-friendly extraction process was developed by the aqueous ethanol extraction with steam explosion pretreatment for obtaining corn germ oil.
  • Can corn germs be milled before oil extraction?
  • Grinding oilseeds prior to oil extraction may enlarge the interface between material particles and aqueous solvent or enzyme, and then enhance free oil yield. In previous research, colloid milling was employed to mill corn germs (Dickey et al. 2010 ). In this study, a dry milling method was developed to grind corn germ.
  • Can ethanol extract free oil from corn germ slurry?
  • Ethanol is a non-toxic and efficient emulsion splitter which has been used in vegetable oil separate emulsion to recover free oil (Chi et al. 2014 ). In the present study, modest ethanol was added into water to be an extraction agent to obtain free oil from corn germ slurry.
