  • What is wheat germ oil?
  • Wheat germ is produced as a by-product in the wheat milling industry. The germ is removed from the endosperm during milling because of its unfavorable baking properties, as the oil is susceptible to oxidation. Wheat germ oil is high in linoleic acid and rich in tocopherols, sterols, and steryl ferulates.
  • How is wheat germ oil produced?
  • Wheat germ oil is produced from germs that are obtained from the grains either by special germ separators or by roller mills as separate grain fraction in the first two breaks (see Section 3.3) . Germs contain around 26% of total grain lipids. Thus the germ is the compartment of the grain with the highest lipid concentration.
  • How to recover wheat germ oil?
  • Various wheat germ oil (WGO) recovery methods have been adopted, including mechanical pressing, solvent extraction, and supercritical fluid extraction. Some modifications reported by different experimental studies to enhance the oil yield retain the nutritional attributes of fresh oil.
  • Which is better solvent extraction or mechanical pressing of wheat germ?
  • Solvent extraction is more efficient than mechanical pressing of WGO. The residual oil content of solvent-defatted wheat germ can be as low as 1% (w/w). Solvent- extracted wheat germ is more stable than the mechanically expressed wheat germ due to its lower lipid content.
