“…beneficial effects on serum lipid levels, and improvement of anti-inflammatory and antimutagenic activities) of sesame seed and seed oil have recently been documented (Lee, Jeung, Park, Lee, & Lee, 2010). Sesame oil with characteristic flavour has a marked antioxidant activity and thus high stability to oxidation (Crew et al, 2006).…”

“…Suja et al [25] have reported that the addition of antioxidants in edible oils such as soybean and sunflower oils is effective in the inhibition of the lipid oxidation. Unrefined sesame oil, on the other hand, possesses high contents of endogenous antioxidants such as sesamolin, sesamin, sesamol, and phenolic compounds [26,27]. In addition, sesame seed roasting prior to oil extraction can improve significantly the oxidative stability of the obtained oils as a result of the antioxidants produced via Maillard reactions.…”

Ascertaining the authenticity of the unrefined sesame oil presents an ongoing challenge. Here, the determination of 2-propenal was performed by headspace solid-phase microextraction (HS-SPME) under mild temperature coupled to gas chromatography with time-of-flight mass spectrometry, enabling the detection of adulteration of unrefined sesame oil with refined corn or soybean oil. Employing this coupled technique, 2-propenal was detected in all tested refined corn and soybean oils but not in any of the tested unrefined sesame oil samples. Using response surface methodology, the optimum extraction temperature, equilibrium time, and extraction time for the HS-SPME analysis of 2-propenal using carboxen/polydimethylsiloxane fiber were determined to be 55 ∘ C, 15 min, and 15 min, respectively, for refined corn oil and 55 ∘ C, 25 min, and 15 min, respectively, for refined soybean oil. Under these optimized conditions, the adulteration of unrefined sesame oil with refined corn or soybean oils (1-5%) was successfully detected. The detection and quantification limits of 2-propenal were found to be in the range of 0.008-0.010 and 0.023-0.031 g mL −1 , respectively. The overall results demonstrate the potential of this novel method for the authentication of unrefined sesame oil.

“…The seeds were roasted at different temperatures and durations, [7]; are then crushed to increase the active surface, thus improve the extraction process. [8] examined the impact of sesame particle size on oil extraction and concluded that The extraction yield increased as the particle size decreased depending on decreasing intraparticle diffusion resistance.…”

In this study, the optimum operating conditions for sesame oil extraction were studied. N-hexane was used as a solvent. Different variables were investigated; sesame seeds particle sizes, ratio of solvent to seeds mass, contact time, stirring effect, roasting impact and extraction temperatures. Results obtained showed that higher rates of extraction were obtained when roasting sesame seed to 150˚C. The ratio of solvent to seeds found to be 6:1 gave higher extraction. Moreover, stirring speed was tested and had been optimized to 600 rpm. Finally, the extraction under heating was studied and results showed that increasing operating temperature to more than 40˚C did not increase extraction efficiency.
