  • How to optimize a process for sesame oil extraction by screw-pressing?
  • Ma. Gabriela Bordón, Box-Behnken designs were used to optimize a process for sesame oil extraction by screw-pressing at low temperature (50 °C). Experimental designs included seed moisture content (SMC), pressing speed (PS), and restriction die (RD) as the main processing parameters.
  • Does screw-pressing improve oil extraction performance?
  • By using screw-pressing at pilot plant scale, optimum oil recoveries from walnut, chia, and almond seeds were obtained at 7.5, 10, and 8% (WB) moisture contents, respectively (Martínez et al. 2008, 2012, 2013 ). In each case, the oil extraction performance was also dependent on the pressing temperature and other processing conditions.
  • How to determine oil content from sesame seeds and pressed cake?
  • Oil contents from both sesame seeds and pressed cake were determined by extraction (10 h) using Soxhlet devices, with n -hexane as solvent. The solvent was removed using a rotary vacuum evaporator at 40 °C. The oil content was gravimetrically determined and expressed as weight percent on a dry basis (AOCS 2009 ).
  • What type of screw press was used?
  • A Komet screw press (Model DD 85—PK1 and PK2; IBG Monforts, Germany) was used. The effective and total lengths and the internal diameter of the press barrel were 6.7, 14.7, and 5.6 cm, respectively. The length and diameter of the screw were 19.5 and 5.3 cm, respectively.
