  • 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.
  • What is the composition of rapeseeds?
  • Materials Rapeseeds ( Alizze) were purchased from a seed producer. The used seeds are food grade as they do not contain euricic acid and have a low glucosinolate content (13 mg/100 g). Their composition is: 9.0% ± 1.2 moisture, 36.0 wt % ± 1.3 of oil and 18.0 wt % ± 0.7 of protein in wet basis.
  • What is a sesame seed?
  • Sesame ( Sesamum indicum L., Pedaliaceae) is a common oilseed crop cultivated in tropical and sub-tropical regions of the world. Sesame seeds have high economical and nutritional value mainly due to their high oil content (45–60%). The world’s sesame oil production was about 4,756,000 tons in 2013 (FAOSTAT 2015.
  • Can twin-screw press increase oleosome extraction yield?
  • The oleosome yield obtained with a single pass through the twin-screw, regardless the media was 60 wt % and it could be increased to 90 wt % with a second pass, indicating the potential of twin-screw press to increase the oleosome extraction yield.
  • How is sesame oil extracted?
  • Sesame oil is usually extracted by means of mechanical screw-pressing. The conventional screw-pressing processes used for SO extraction generally include a previous seed roasting step. Although seed roasting can increase oil recovery, it may have deleterious effects on oil quality.
  • 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 ).
