• How to extract WGP from defatted wheat germ?
  • Extraction of WGPs Currently, the leading technologies for extracting WGPs from defatted wheat germ include alkali extraction, microwave- or ultrasonic-assisted alkali extraction, subcritical water extraction, enzymatic extraction and reverse micelle extraction (Fig. 1) (Amagliani et al., 2017; Wen et al., 2019; Leal et al., 2021).
  • 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?
  • Wheat germ oil is a valuable by-product from wheat grain which is a good source of important nutraceuticals such as ¦Á- and ¦Â-tocopherol. Extraction of this oil from wheat germ is important for the effective utilization of its various potential nutraceuticals that have reported health benefits.
  • Is wheat germ oil a resource waste?
  • However, WGPs have not been fully exploited because wheat germ is typically used for wheat germ oil extraction, generating a partial resource waste (Majzoobi et al., 2022). WGPs contain eight essential amino acids with relatively high levels of lysine, isoleucine, valine and leucine.
  • Where did wheat germ come from?
  • Fresh wheat germ was obtained from the variety Tiriticum aestivum L. just after the milling at a local flour mill owned by the ONEL Company, Konya province, Turkey. A sufficient amount of wheat germ was used for oil extraction and the remaining samples were stored in air tight packages at -18 ¡ãC for enzyme analysis.
  • What reagents were used for oil extraction?
  • A sufficient amount of wheat germ was used for oil extraction and the remaining samples were stored in air tight packages at -18 ¡ãC for enzyme analysis. All reagents and solvents used were of analytical grade.
