  • 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.
  • How to extract corn germ oil in semi-batch process?
  • The extraction of corn germ oil was evaluated using pressurized propane as solvent in semi-batch process as an alternative approach to organic solvent extraction. The effect of temperature (20, 40, 60 °C), pressure (20, 60, 100 bar), particle size and confinement time were studied.
  • Can hexane extract be used to extract corn germ oil?
  • Extraction with subcritical propane resulted in corn germ oils with properties similar to those obtained in classic extraction procedures using hexane. However, both propane and hexane extracts had lower total phenolic content and antioxidant activity compared with Soxhlet extraction with ethanol or ethyl acetate.
  • 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.
