Acid value is an indicator for the edibility of oil and suitability for industrial use. Pistachio nut oil has 1.00 ± 0.03 mg KOH/g oil,which falls within the recommendation codex of 10 mg KOH/g for edible oils (Codex Alimentarius, 1999). Pistachio oils present low values of free fatty acid (FFA%) 1% oleic acid (Table 3). It is possible to deduce that oils obtained can be stored for a long time without deterioration. The results suggest that the oils are edible and can also be used in the manufacture of paint and varnishes, comparable to the results of Dosunmu and Ochu (1995). During the 12 months of storage, the acidity of control sample increased significantly (p < 0.05) from 1.00 to 1.42% (Table 3), which could
be due to production of organic acid. These results were in agreement with the literature that the free fatty acid content of walnut increased with increasing the storage periods (Al-Bachir, 2004).
