  • What is the best extracting solvent for olive cake?
  • Hexane was found to be the best extracting solvent with an oil yield of 12.7%. Oil yield increased from 10% to 16% when olive cake was soaked with aqueous sodium chloride solution for 24 hours. Sorbitan monoleate surfactant enhanced the extraction of oil.
  • How to extract oil from olive cake?
  • Olive cake samples were dried in an oven at 70°C and 105°C for 3.5 hours before being used in the extraction experiments. Hexane was found to be the best extracting solvent with an oil yield of 12.7%.
  • What type of olive cake was used for the experiment?
  • The used olive cake for the experimentation was of Chamlal variety. It was obtained from the olive oil mill “Ifriolive” located in the area of Bejaïa (north east of Algeria). Its initial moisture content was 45.8 0.5% (w/w) which was reduced to 6.2 0.4% by drying in an oven at 103 °C.
  • How long does it take to extract oil from oil cake?
  • So the oil cake might not be grinded properly to reach high extraction.  The experiment was completed after only 5 full cycles which took 1 hour. The extraction time has a fundamental importance for oil recovered from oil cake. The higher the extraction time the higher the amount of oil extracted.
  • How to increase oil extraction rate in a Soxhlet?
  • To enhance the extraction rate later in the Soxhlet, the dried solid samples were soaked in a sodium chloride solution (2 M) for 24 h then rinsed with distilled water and dried for 3 h at 70 • C. Selecting the optimal concentration of the NaOH solution will facilitate the rupture of olive cake cells, which increases the oil extraction process.
  • How does aqueous sodium chloride solution affect oil extraction?
  • Oil yield increased from 10% to 16% when olive cake was soaked with aqueous sodium chloride solution for 24 hours. Sorbitan monoleate surfactant enhanced the extraction of oil. Particle size of olive cake and solvent volume had significant effect on oil extraction.
