  • 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.
  • How is corn germ extracted?
  • The germs were kept in paper bags in the darkened room. The moisture content in the corn germ, determined by drying germ to constant weight at 105 °C, was 3.3 g/100 g. Before oil extraction, the corn germ was ground by a domestic grinder (Braun, Germany) for 2 min.
  • 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.
