Characteristics of fruit and oil of terebinth (Pistacia terebinthus L) growing wild in Turkey

Nutrients and physical properties were determined in terebinth (Pistacia terebinthus L) fruits from çel, Turkey to investigate their potential uses. Ripe fruits were evaluated for moisture, crude protein, crude oil, crude fibre, crude energy, ash, HCl-insoluble ash, essential oil yield, dimethyl sulphite, weight and width/length ratio. Relative density, refractive index, free fatty acids, peroxide value, iodine value, saponification number, unsaponifiable matter and carotenoid content were determined in the fruit oil. The main fatty acids identified by gas chromatography were oleic (52.3%), palmitic (21.3%) and linoleic (19.7%) acids. Contents of Na, K, P, Ca, Fe, Mg, Zn, Cu, Mn, Li, Ni, Pb, S, Se, Cd, Co, Cr, Sr, Ti, V, Ag, Al, As, B, Ba and Bi were also determined in the fruits. The fruits were found to be rich in protein, oil, fibre, unsaturated fatty acids and minerals, suggesting that they may be valuable for food uses. The data may also be useful for the evaluation of nutritional information.
