• What are the methods of oil extraction from oil seeds?
  • Conclusions Oil extraction methods from oil seeds include conventional methods (solvent and mechanical extraction) and nonconventional or improved techniques (supercritical fluid extraction, ultrasound, microwave, and enzyme assisted extraction.
  • Why is plant oil extraction important?
  • Extraction through these novel industrial techniques is helpful for the oxidative stability of plant oils and provides better yield than traditional methods. The oil extract from seeds is used to develop different functional foods. Plants-oil is more valuable and cost-effective.
  • Can supercritical fluid extraction extract seed oils?
  • The selectivity, low applied extraction temperatures, and in many cases short processing times, have led to the extensively use of this technique in extracting seed oils. Specifically, in this review we discuss the use of the supercritical fluid extraction technique to extract seed oils.
  • Does mechanical pressing extract oil from oilseeds?
  • Mechanical pressing is commonly employed to extract oil from oilseeds and is dependent on pretreatment of raw seed material (Mildner-Szkudlarz, R¨®?a¨½ska, Siger, Kowalczewski, & Rudzi¨½ska, 2019). However, mechanical pressing processes have a low extraction efficiency (<70% oil is extracted).
  • Is the oil extraction process reproducible from beauty leaf seed?
  • Bhuiya et al. studied the oil extraction process from beauty leaf seed of Australian origin and observed that the solvent extraction process was more reproducible, with relative ease of seed preparation and did not require extensive training compared to the mechanical extraction method.
  • What seeds can be used for oil extraction using SFE?
  • The most important economically viable seeds for extraction of oil using SFE in the industrial scale include more recently hemp (Cannabis sativa L.) seed, rasp grape seed, berry seed, and date seed, since a number of these seeds are discarded as an industrial waste, therefore they can be utilized for the green production of oil.
