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 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¨C60%). The world¡¯s sesame oil production was about 4,756,000 tons in 2013 (FAOSTAT 2015.

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