  • Why is extraction of wheat germ oil important?
  • Extraction of this oil from wheat germ is important for the effective utilization of its various potential nutraceuticals that have reported health benefits. This review also explains detailed chemical composition, processing, functional activities, and potential utilization of wheat germ oil.
  • What is wheat germ oil (WGO)?
  • Abstract Wheat germ is a valuable by-product of the wheat milling process, represents 10-15% lipid contents with other bioactive compounds. Various wheat germ oil (WGO) recovery methods have been adopted, including mechanical pressing, solvent extraction, and supercritical fluid extraction.
  • How is wheat germ oil produced?
  • The most economical technique for producing wheat germ oil is the so-called ¡°prepress solvent extraction¡± process. First, germs are pressed at low pressure, leaving 15¨C20% of oil in the residue, followed by solvent extraction.
  • 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.
  • Is wheat germ oil a good source of health benefits?
  • Oil obtained from wheat germ is found to be a good source of various nutritionally beneficial constituents and carry important health benefits and functional properties. The review will help researchers to carry out further research to improve processing and the quality of oil besides emphasizing on its beneficial aspects.
