- Abstract
In this study for which terebinth seeds obtained from Elazığ were used and the obtained oil physical/chemical properties are investigated. Because these properties are quite effective on oil quality. At first the composition of terebinth was determined in terms of nutritional elements (crude oil, crude protein, crude cellulose, etc.). According to soxhlet method, it was determined that terebinth seeds included 47% (w/w) oil. Some physical and chemical properties of oil samples such as free acidity, peroxide value, saponification number, iodine number, quantity of unsaponifiable matter, sediment, viscosity, specific gravity and refraction point were defined by using various types of solvents. It was concluded that the terebinth oil extracted with petroleum ether was different in terms of peroxide value and it was not sufficient when compared to oil samples obtained by other solvents. Finally, oil acidity composition was determined by using GC-FID and it was confirmed that terebinth oil was composed of about 74% unsaturated fatty acids and 26% saturated fatty acids. Through mean values, it was determined that terebinth oil included 45.8% oleic, 23.93% linoleic (ω-6), 0.47% linolenic (ω-3), 3.78% palmitoleic, 24.27% palmitic and 1.7% stearic acid. Oleic acid, linoleic acid and palmitic acid were considered as main fatty acids of terebinth oil.
