Abstract

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.
