This study investigates the physicochemical properties, fatty acid composition, and antioxidant potential of cold-pressed Nigella Sativa oil enriched with thymoquinone. The raw black cumin seeds used in the study exhibited a moisture content of 3.25±0.28%, an oil content of 37.53±0.73%, a protein content of 18.71±0.48%, and an ash content of 5.16±0.47%. The oil yield obtained through the cold press extraction method was 22.33±0.58%. The cold-pressed oil exhibited a free fatty acid content of 8.24±0.30% as oleic acid, a peroxide value of 9.56±0.43 meq O2/kg lipid, an iodine value of 119.27±5.97 I2/100 g, and a saponification number of 204.76±10.66 mg of KOH/g of oil. The oil was found to be rich in unsaturated fatty acids, particularly linoleic and oleic acids, and had a thymoquinone content of 0.28%. In an effort to enhance the thymoquinone content, the essence of Nigella Sativa oil was extracted, yielding a thymoquinone content of 60%. This essence was then added to the Nigella Sativa oil, resulting in an enriched oil with a thymoquinone content of 2.96%. The results indicate that the cold-pressed Nigella Sativa oil enriched with thymoquinone has good physicochemical properties and antioxidant potential, making it a promising ingredient for nutritional and medicinal applications.
