• 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.
  • Is expeller pressing better than solvent extraction?
  • However, both methods have some major pitfalls to overcome: a lower oil yield with expeller pressing compared to solvent extraction can make the process economically disadvantageous, and the use of organic solvents brings environmental concerns.
  • 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.
  • How do you extract pumpkin seed oil?
  • Pumpkin seed oil can be extracted one of two ways, either through cold-pressing or by expeller pressing the seeds.
  • How does a pilot expeller press affect linseed oil yield?
  • When using a pilot expeller press designed for cold pressing, increasing rotation from 1.2 to 18 rpm increased press capacity from 2.2 kg seed/h to 29.4 seed/h, while decreasing canola oil yields from 91 to 84% . Additionally, the number of presses was shown to affect the oil yield and the quality of linseed oil.
  • Is pumpkin seed oil a sustainable product?
  • The sustainability factor can be improved by using the byproducts and managing waste properly. If these factors are considered and implemented into the manufacturing process, pumpkin seed oil production can be considered as a sustainable product. These seeds are rich in antioxidants.
