Quality characteristics (acidity, peroxide values, K232, K270, oxidative stability) and chemical compositional data (fatty acids, sterols and triacylglycerols) were studied in virgin olive oil samples from olive trees, cv Koroneiki, subjected to different water regimes. Experimental trials were carried out using three-year old own-rooted olive trees (Olea europaea L) variety Koroneiki. Plants were subjected to two irrigation treatments to maintain soil water potential to -0.03 MPa and -1.5 MPa. Results showed that irrigation significantly increased the fruit oil content and the oxidative stability and peroxide value of the resulting oil. Olive oil from fruits of irrigated trees showed significant higher values in total saturated fatty acids. Total sterols were also significantly influenced by irrigation. Acidity and specific absorption coefficients K232, K270, of olive oils were not significantly affected.
