Table 1 presents the experimental conditions for the extraction of sesame seed oil using carbon dioxide and propane as solvents. The extraction yield was calculated as the mass of the oil extracted by the mass of raw material fed into the extractor. The calculation of the extraction yield was performed at a fixed mass of pressurized solvents in order to permit a direct comparison among distinct experimental conditions: 450 g for the carbon dioxide extractions and 40 g in the cases of propane extractions
