Description: Investigation was carried out on the effects of heating temperature (40 to 85?C), heating time (5.0 to 27.5 min), moisture content (6.1 to 12.0%) and applied pressure (15 and 20 MPa) on the yield, color, refractive index, and specific gravity of oil expressed from sesame seeds using a laboratory press. The yield of oil was affected but the color, specific gravity and refractive index were not affected by processingconditions within the range considered. The oil yieldwas increased withdecreasein moisture contentof sample after heating. Highest oil yield (based on total mass expressed) of 33.5% corresponding to an expression efficiency (basedon seed oil content) of 65.7% was obtained when sesame seeds were condi tioned to moisture content of 6.1%, heated at 85?C for 20 min, and expressed at a pressure of 20 MPa. Theaverage values of refractive index andspecific gravity were1.47and0.918respectively while the colorof the oil was yellow (i.e. a Munsell color notationof 2.5Y).
