  • 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.
  • What is corn germ oil processing by-products?
  • Corn (Zea mays L.) is one of the most relevant and cultivated cereals. During the processing of corn, especially in obtaining edible oil, large quantities of by-products are generated, called corn germ oil processing by-products. In this sense, this chapter provides...
  • How is corn germ isolated from starch?
  • During the wet milling process, the germ is isolated from the starch using cyclone separators, washed, and dried. The dried germ contains about 50% oil, in which the oil constitutes about 85% of the total amount of oil present in the corn.
  • Why is corn germ oil a good source of protein?
  • Corn germ oil can reduce the risk of chronic diseases and exhibits a long shelf life, because of its high content of unsaturated fatty acids and tocopherols [41¨C43]. Regarding proteins, albumins, globulins, water-soluble and saline-soluble proteins, represent over 60% of germ protein which accounts for 29% of total kernel protein [44, 45].
  • What is corn germ oil?
  • Corn germ oil is a by-product of the corn oil milling process. Most corn that is harvested is used as feed but the proportion of the corn that is milled is increasing because of bioethanol production. During the wet milling process, the germ is isolated from the starch using cyclone separators, washed, and dried.
