  • 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 ).
  • How to extract oil from corn germ during flour processing?
  • This 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.
  • 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.
  • Does Tempering degerming reduce endosperm fractions in corn germ-bran mixture?
  • The 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.
  • Can absolute isopropanol be used in corn germ-bran oil extraction?
  • The absolute isopropanol showed excellent performance as a solvent in corn germ-bran oil extraction, with yields above 75% from the temperature of 50 °C, in single stage batch extraction.
  • What are the TPC values of corn oil extracted by hexane?
  • The TPC values of oils extracted at 45 °C and boiling hexane are consistent with those reported by Shende and Sidhu (2015) for corn oil extracted by hexane (76 mg GAE/kg oil). The highest yield of extraction (37.7 g oil/100 g CG) was obtained by the Soxhlet ethanol method.
