How to optimize a process for sesame oil extraction by screw-pressing?

Ma. Gabriela Bord¨®n, Box-Behnken designs were used to optimize a process for sesame oil extraction by screw-pressing at low temperature (50 ¡ãC). Experimental designs included seed moisture content (SMC), pressing speed (PS), and restriction die (RD) as the main processing parameters.

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.

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 (Mart¨ªnez et al. 2008, 2012, 2013 ). In each case, the oil extraction performance was also dependent on the pressing temperature and other processing conditions.

How is oil extracted?

Oil extraction was carried out in a single step with a Komet screw press (Model CA 59G; IBG Monforts, Germany). The effective and total lengths, and the internal diameter of the press barrel were 3.1, 7.0, and 3.5 cm, respectively. The length and diameter of the screw were 15.0 and 3.0 cm, respectively.
