  • How to improve oil yield using screw press and n-hexane techniques?
  • To improve the oil yield using screw press and n-hexane techniques, several pretreatments which include preparation and extraction, grating, drying and moisture conditioning of the seed kernel are usually made before oil extraction.
  • Are exposed kernels used in screw press & n-hexane?
  • The literature search has shown that the exposed kernels have been used in both screw press and n-hexane techniques to achieve a higher yield of oil (Jahirul et al., 2013). The removal of shell of the seed is important as this absorbs oil during extraction which results in the lower yield of oil (Willems et al., 2008).
  • What is the difference between screw press and solvent extraction?
  • It has been found that the oil yield obtained by the solvent extraction technique was higher in comparison to the mechanical (screw) pressing (Bargale et al., 1999; Willems et al., 2008). The mechanical screw press technique was found inefficient because of the lower yield of oil.
  • Which is better screw press or n-hexane method?
  • Relative advantages and disadvantages of oil extraction between screw press and n-hexane techniques. In comparison to both methods, the results showed that n-hexane method is better in terms of higher oil yield as well as fossil energy ratio.
