FAQ

  • QHow to extract oil from corn germ during flour processing?
    AThis work aimed the recovery of oil and protein fractions from corn germ (CG) generated as a by-product during flour processing. Several oil extraction techniques were investigated: hexane at room temperature, hexane at 45 °C, supercritical carbon dioxide (Sc-CO 2) and Soxhlet with hexane and ethanol.
  • QWhat is corn germ?
    ACorn 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.
  • QAre you a manufacturer or a foreign trade company?
    AYes, we are a manufacturer. Our company is specializing in edible oil processing solutions and equipment, we provide complete plant solutions for oil seeds pressing, solvent extraction, oil refining and oil deep processing.
  • QHow is corn germ oil produced?
    ACurrently, 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 ).
  • QCan corn germs be milled before oil extraction?
    AGrinding 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.
  • QDoes Tempering degerming reduce endosperm fractions in corn germ-bran mixture?
    AThe tempering-degerming process implemented to achieve the corn germ-bran mixture may let more endosperm fractions attached to the germ than the dry mechanical degerming and bran separation implemented by Castelmais. 3.2. Oil recovery and characterization Table 1 summarizes data of yields and oil composition for the different extraction methods.
  • QCan aqueous ethanol extract corn germ oil?
    AThis 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.
