• How is soybean oil extracted?
  • Extrusion has been used as pretreatment prior to expeller pressing of soybean oil, extracting over 70% of oil compared to single-step expelling, which yielded 60% . This process has also been used for simultaneous treatment with fatty acid methyl ester as a solvent, extracting 98% of oil from sunflower seeds .
  • What are the disadvantages of soybean oil production compared to hexane extraction?
  • However, its downside was generating the highest GHG (about 11 times more CO 2 and CH 4 emitted from 1 kg of soybean oil production compared to hexane extraction) and the highest criteria pollutant emissions due to the energy used during pressing.
  • Is there a market for non-soybean oil?
  • While the edible oils market (mostly represented by soybean oil) is forecasted to reach 632 million tons by 2022, there is increasing interest to produce non-soybean, plant-based oils including, but not limited to, coconut, flaxseed and hemp seed.
  • Why is tea used in extruder-expelling of soybean oil?
  • During expeller pressing, the solid residue made of fiber and protein often has residual oil, which adds value to this co-product. When TEA was applied to a two-step extruder¨Cexpelling of soybean oil extraction, it was found that soybean meal was the driving force in profits, contributing 75% of total revenues .
  • How can a peanut seed extract be destabilized?
  • Cream from peanut seed extraction was also destabilized using alkaline protease, achieving a 65% free oil yield. This was a steep increase compared to the cream from the control, which had less than a 5% free oil yield . Additionally, enzymes can be used to increase protein recovery from the skim layer.
  • Is oil extraction better than aqueous extraction of Forsythia suspense seeds?
  • Yields of 76% of oil and 75% of protein were reported, which were significantly higher compared to aqueous extraction leading to yields of 56% of oil and 61% of protein . The oil extraction of Forsythia suspense seeds was improved using a cocktail of cellulase, pectinase and proteinase (17 vs. 7% for AEP, respectively).
