The fatty acid content of pistachio nuts was not significantly different from Antep varieties as determined by Maskan and Karatas (1998), but was different from the Kerman variety (Shokraii, 1977). High oleic acid content provides the food with a good stability and a diet very rich in this fatty acid reduces the concentration of cholesterol (Garcia, Agar, & Streif, 1992). Pistachio samples were also found to contain significant amounts of linoleic (17.7%) acid, an essential fatty acid.
