Solvent extraction method was carried out using soxhlet apparatus to extract sesame oil from sesame seed. The primary processing of sesame seed before oil extraction include drying, crushing and separating. These ruptures the oil cells for efficient extraction. Various experiments were carried out regarding different processing parameters like particle size, particle moisture content, nature of the solvent used, pretreatment with salt and extraction time in order to find out their affect on solvent extraction of sesame seed. The results showed that after drying at 105o C, off white variety of sesame seed with an average particle size of 24 mesh and 28 mesh (87.5% and 12.5% in mass respectively) gave maximum oil yield with n-hexane solvent. The extraction was carried out for 4 hours. The physicochemical qualities of the oil were also determined.
