  • Can oil and protein extracts be recovered from corn germ?
  • Oil and proteins were successfully recovered from corn germ by a biorefinery scheme. Oil extraction yield and TPC of oils were influenced by the polarity of solvents. The protein content of recovered extracts ranged from 20 to 48%. The functionality of protein extracts depended on the defatting pretreatment.‌
  • How is corn oil extracted?
  • In the process of corn oil extraction, the germ passes through conditioning operations (heating, humidification and extrusion), to then be submitted to oil extraction by expeller (pre-pressing) and solvent extraction, with hexane being the solvent chosen by processors ( Moreau, 2005 ).‌
  • Does corn germ oil contain sterol?
  • The contents of sterol, tocopherol and carotene from the oils of corn germ and bran. As a kind of high-quality vegetable oil, corn germ oil has been studied for many years by using lots of extraction methods including pressing extraction, Soxhlet extraction, organic solvent extraction, supercritical CO 2 and aqueous enzymatic [124, 125, 132–134].‌
  • 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 .‌
  • 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 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.
