  • What is mechanical oil extraction?
  • Conventional oil extraction Mechanical oil extraction, also known as cold pressing or expeller pressing, is a method of extracting oil from oilseeds using mechanical means without the use of solvents or chemicals. It is a simple and traditional method that preserves the natural flavor, color, and nutrients of the oil ( Fig. 6.2 ).
  • Is ethanol a safe extractant for vegetable oil extraction in UAE?
  • Organic solvents, such as ethanol, methanol, and hexane have been reported for UAE extraction of vegetable oils; however, ethanol has been granted the Generally Recognized as Safe (GRAS); so, this is the preferred choice as extractant to extract bioactive compounds and due to lack of any safety concerns ( Ameer, Shahbaz, & Kwon, 2017 ).
  • Are there alternative green solvents for extraction of plant-based oils?
  • Moreover, extraction of plant-based oils may result in the consumption of high amounts of hexane; hence, there is a dire need to expedite the process of exploring alternative green solvents, such as ionic liquids, terpenes, and aqueous enzyme-assisted extraction.
  • Is mechanical extraction better than solvent extraction?
  • However, mechanical extraction may result in lower yields compared to solvent extraction methods, and the extracted oil may contain more impurities, such as sediment and moisture. Additionally, some oilseeds may require additional processing steps, such as heating or steaming, to soften the seeds and improve the oil yield. 6.4.
