• How is oil extracted from seeds?
  • Commercial large-scale extraction of seed oils is typically based on solvent extraction or mechanical extraction. 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).
  • What are the different types of seed oil extraction methods?
  • Some of them include microwave assisted extraction (MAE), ultrasound-assisted extraction (UAE), pressurized liquid extraction (PLE), and supercritical CO 2 extraction (SC-CO 2) (Danlami, Arsad, Zaini, & Sulaiman, 2014). The main aim of this review is to is to provide an updated review on the current use of SFE to extract seed oils. 2.
  • 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).
  • 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.
  • Can ultrasonic assisted extraction extract seed oils for multifaceted food applications?
  • The application of ultrasonic assisted extraction to extract seed oils for multifaceted food applications is discussed in this study. Seed oils, which are notable sources of health-promoting characteristics and reservoirs of fatty acids and phytochemicals, are being targeted for effective extraction.
