• 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.
  • Do soybean co-products add value to EAEP extraction?
  • During expeller pressing, the solid residue made of ?ber and protein often has residual oil, which adds value to this co-product. When TEA was applied to a two-step ]. Similarly, the importance of soybean co-products on the techno-economic value of EAEP extraction was demonstrated.
  • Does compression pressure affect the extraction yield of soybean oil?
  • In addition to temperature, Gikuru and Lamech , also studied the effect of compression pressure and duration of applied force on the extraction yield of soybean oil using the traditional optimization method of keeping some factors constant while varying one at a time.
  • Which methods are used in vegetable oil extraction?
  • From the preceding analysis, it is observed that recent research on vegetable oil extractions has been focused more on the assisted methods (microwave and ultrasound) and supercritical fluid extraction compared to the conventional solvent and mechanical extraction methods.
  • Does enzyme extraction yield a lower yield than conventional Soxhlet extraction?
  • Despite some of these recorded successes with enzyme extractions, it is worth noting that Anwar et al. reported a lower yield for enzyme extraction (35.2%¨C38.0%) compared to the conventional soxhlet extraction (42.6%) in a study with viscozyme, feedzyme, and kemzyme assisted cold press extraction of oil from flaxseeds.
  • Can enzymes be used to extract oil by AEE?
  • Two barriers (oilseed cell wall and oil body interfacial membrane) need to be overcome to extract oil by AEE. The selection, application, and influencing factors of enzymes in AEE were discussed. UAEE, MAEE, UMAEE, and PAEE can increase the oil yield and shorten the extraction time. Immobilized enzymes can increase the reusability of enzymes.
