Abstract

This study was conducted to determine the main physiochemical properties of sesame oil extracted from three sesame seeds samples, the differences between mixed (A-C) and the sieved sesame seed (A1-C3): which were taken from Sharzoor in Sulaymaniyah (S, mixed brown), Akre in Duhok (A, mixed brown) and Mala Omar in Hawler (MO, mixed brown). And to evaluate the differences between the OIL characteristics of mixed (Akre ,A, Sharzoor B, Mala Omar ,C ) and the sieved seeds with three different mesh size sieve (1.50, 1.35, 1) mm included (A1,A2,A3,.B1,B2,B3 ,C1,C2 and C3). The properties that included to study in this work were viscosity, specific gravity, fatty acid content, acid value, iodine value, and peroxide value. From the results of this study, it was found that the Mala Omar sample in all parts especially C2 48.42% is considered good source for oil, the viscosity of (hawler) samples especially C3 with 0.0490 Pas, the lowest viscosity while the A1 has a maximum viscosity 0.0525 Pas. More than 80% of sesame seeds' fatty acid composition is unsaturated, with high concentrations of oleic, linoleic, and lenolinic acids. Saturated fatty acids, primarily palmitic and stearic acids, account for the remaining 20%. Acid value in sample A1 of sharazoor sesame oil had the lowest content (2.1030 mg KoH\gm oil), whereas sample C3 had the greatest concentration. Omar Mala 15.5815. A3 sharazoor sample a higher 11.4954 gm I2\100gm oil, iodine value. While the maximum peroxide value was found in the B3 sesame oil sample of 15.9267 meq/kg, and the lowest peroxide value was found in the B sesame oil sample at 3.8850 meq/kg.
