Abstract

The work is devoted to a comparative study of the fatty acid composition of white and black sesame oils, as well as the development of a relatively effective method for isolating the natural antioxidant sesamol. The purpose of this work was to determine the comparative indicators of the content of fatty and free organic acids in the studied oils by gas and high-performance liquid chromatography, confirm their suitability and further use. The optimal conditions for obtaining high-quality unrefined oil from sesame seeds for the food and pharmaceutical industries were determined by the method of cold pressing (pressing chamber temperature was 100℃, oil outlet temperature was ≤ 40℃). Under these conditions, the oil yield was 30% and 27%, respectively. It was shown that finished sesame seed oils contain a highly effective natural antioxidant sesamol (oxyhydroquinone methyl ester) – 0.140 mg/kg, due to which they can be stored at room conditions for more than 3 years. The extracts of squeezes of sesame oils contain valuable free organic acids: oxalic – 0.017 mg/mL, malic – 0.02 mg/mL, fumaric – 0.001 mg/mL. Based on the research, the fatty acid composition of oils was determined and a relatively effective method for the complex processing of sesame raw materials was developed to obtain a highly effective natural antioxidant sesamol.
