Quality of Edible Sesame Oil as Obtained by Green Solvents: In Silico versus Experimental Screening Approaches

Abstract

The present study aimed to investigate the qualitative and quantitative performance of five green solvents, namely 2-methyltetrahydrofuran (MeTHF), cyclopentyl methyl ether (CPME), p-cymene, d-limonene and ethanol to substitute n-hexane, for sesame seed oil extraction. In fact, both CPME and MeTHF gave higher crude yields than n-hexane (58.82, 54.91 and 50.84%, respectively). The fatty acid profile of the sesame seed oils remained constant across all the solvent systems, with a predominance of oleic acid (39.27–44.35%) and linoleic acid (38.88–43.99%). The total sterols gained the upmost amount with CPME (785 mg/100 g oil) and MeTHF (641 mg/100 g oil). CPME and MeTHF were also characterized by the optimum content of tocopherols (52.3 and 50.6 mg/100 g oil, respectively). The highest contents of total phenols in the sesame seed oils were extracted by CPME (23.51 mg GAE/g) and MeTHF (22.53 mg GAE/g) as compared to the other solvents, especially n-hexane (8 mg GAE/g). Additionally, sesame seed oils extracted by MeTHF and CPME also had the highest antioxidant and anti-inflammatory properties as compared to the other green solvents and n-hexane, encouraging their manufacturing use for sesame seed oil extraction.

Semi-industrial Countercurrent Extraction of Soybean with 2-Methyloxolane for High-Quality Protein and Oil

“…However, the method used to determine the UM does not consider polar unsaponifiable substances that are not soluble in petroleum ether such as phenolic compounds. Several studies have reported that 2-MeOx is also an efficient solvent for the extraction of phenolic compounds and yields polyphenol-rich extracts with high antioxidant activity. ,, In this study, the oil obtained with 2-MeOx contained a significantly higher concentration ( p < 0.05) of polyphenols than the oil obtained with hexane. The higher content of UM and phenolic compounds was probably the reason for the longer oxidative stability (induction time >70 h) compared to the hexane-extracted oil.…”

Sesame Seeds: A Nutrient-Rich Superfood

“…Sesame oil shows a highly favorable fatty acid profile, comprising approximately 80-85% unsaturated and merely 15-20% saturated fatty acids. Sesame oil primarily contains linoleic (35-50%) and oleic (35-50%) acids, alongside minor quantities of palmitic (7-12%) and stearic (3.5-6%) acids and negligible levels of linolenic acid [227,228]. Recent scientific studies have shown that an excessive intake of n-6 fatty acids might cause a physiological condition that heightens platelet aggregation and blood clotting.…”
