• Which oil is used in an oilseed press?
  • An oilseed press can be used to press oil from a wide variety of seeds and nuts, including soybean oil (also known as ‘vegetable oil’), corn oil, sunflower oil, canola oil, peanut oil, olive oil, and safflower oil.
  • 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.
  • 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 .
  • How much oil does an oil seed press produce?
  • The capacity of an oil seed press is often given in the weight of seeds that can be processed per hour. For canola seeds, about one third of the seed weight going into the press will be produced as oil, while the remaining two thirds will be meal.
  • 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).
  • What are the different types of small oilseed presses?
  • There are two major types of small oilseed presses: screw presses (also known as expeller presses) (Figure 2) and reducing screw/cage presses. Many are made overseas, while at least one is now available from a United States manufacturer.
