Resumen:
Box-Behnken designs were used to optimize a process for sesame oilextraction by screw-pressing at low temperature (50 ºC). Experimental designsincluded seed moisture content (SMC), pressing speed (PS), and restriction die (RD)as the main processing parameters. Extractions at pilot plant scale showed apeak in oil recovery (OR, 71.1 ± 2.80 %) at 12.3 % SMC, 4 mm RD,and 20 rpm PS. Theoretical models were scanned against experimental data in order toscale-up the proposed oil extraction process to industrial scale. A fitted model forOR showed a maximum predicted value similar to the highest experimental value (74.4± 1.23 %) under the following conditions: 8.03 % SMC, 10 mm RD, and 20 rpm PS. Chemical qualityparameters of oils obtained at both pilot and industrial scales were in theranges stated in Codex (FAO/WHO) standards for non-refined sesame oil.
