Abstract

Fatty acids are the largest component group of olive oils. Fatty acid composition is one of the most frequently used criteria in the characterization of olive oils. Therefore, in this research, the fatty acid composition of 6 olive oil samples taken from local markets in Kahramanmaraş city (Türkiye) was analyzed. Using the fatty acid composition, unsaturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, saturated fatty acids, iodine value and quality index were calculated. It was determined that the oleic acid and linoleic acid contents of the samples (in fatty acids) were between 71.40-73.08 and 6.96-9.16 % in fatty acids. With future studies, more detailed and comprehensive information can be obtained about the olive oils offered for sale in local markets. In this way, it is thought that useful information can be provided to consumers and manufacturers who want to produce quality products.
