It is a fact that qualitative characteristics of olive oil are influenced by environmental conditions and cultivars. Keeping this in mind, the present has tried to investigate some oil-related qualitative characteristics of Tarom 2 and Dezful olive cultivars, conducting an experiment as a randomized complete block design with 3 replications at Shahid Chamran University of Ahvaz between 2016 and 2017. Results indicate that the oil, extracted from Tarom 2 cultivar exhibit the highest peroxide value (9.25 meq of O2/ kg of oil), chlorophyll content (8.10 mg/kg of oil), and carotenoid (0.16 mg/kg of oil), not to mention K232 and K270 extinction coefficients, which have been 2.32 and 0.61, respectively. However, the total phenolic content of the oil, extracted from Dezful cultivar (552.66 mg/kg of oil), has been higher than that of the other cultivar. In addition, the highest oleic acid content (58.52%) and lowest palmitic acid content (17.6%) have been measured in the oil obtained from Tarom 2 cultivar, while the oil extracted from Dezful cultivar has had the highest linoleic acid content (18.05%). Furthermore, oleic acid-to-linoleic acid ratio has been higher in the oil, extracted from the Tarom 2 cultivar rather than the one taken from the Dezful cultivar. Therefore, based on the results obtained from the experiment, the oil extracted from Tarom 2 cultivar is expected to exhibit higher oxidative stability than that of the Dezful cultivar.
