A Case Study on Profile Investigation of Cold-Pressed Black Cumin Seed Oil Produced in Turkey

In this study, it is aimed to determine the fatty acid compositions of obtained from Almond, Black Cumin, Terebinth, Chia, Mustard, Bitter Apricot Kernel, Native Sesame, White Sesame, Flax, Safflower, Canola, Poppy, Peanut, and Coconut nutmeg oils by cold pressing method. Methods and Results: A single head screw cold press (Koçmaksan, İzmir, 1.5 kW, 220 volts) with a crushing capacity of 5 kg per hour was used for the extraction of oils from plants. Obtained oils were filtered with filter paper to remove particulates and filled into 10 ml brown glass bottles without any air space and stored at -18°C until analysis. When these plants were evaluated in terms of fatty acid composition, it was determined that they contain nine saturated, six monounsaturated, and seven polyunsaturated fatty acids. The highest total saturated fatty acid was obtained from coconut oil with 84.78%. The highest total unsaturated fatty acid content was obtained from Canola oil with 91.19%, the highest monounsaturated fatty acid content was obtained from Bitter Apricot kernel oil with 67.04%, and the highest polyunsaturated fatty acid content was obtained from hashish with 69.76%. The P (polyunsaturated fatty acids) /S (saturated fatty acids) values of the plants whose oil is extracted by the cold pressing method vary between 0.02-10.43. The highest P/S values of the oils were obtained from Canola with 10.35% and bitter apricot kernel oil with 9.96%, respectively. Conclusions: Coconut oil remains below World Health Organisation (WHO) standards in terms of P/S value and is classified as non-consumable directly as food. It has been concluded that the other cold-pressed oils examined may be among the oils that can be used as edible oils in terms of both closing the edible oil industry gap and health benefits due to having a balanced fatty acid composition. Significance and Impact of the Study: Oils are used in many fields such as oils, edible oil, soap, perfumery, and other industries according to their fatty acid composition. In this study, the chemical data of the oils obtained by cold pressing are combined in a single data set to provide easy data for researchers.
