heal.abstract	Bulk oils and oil-in-water emulsions were subjected to high hydrostatic pressure (HHP) (200 650 MPa) treatment so as to estimate the effect of applied pressures on lipid oxidation HHP-treated and non-treated samples were left to autoxidise under accelerated conditions (2 weeks 70 degrees C) and their oxidative status was periodically estimated by measurement of conjugated dienes and peroxide value Total changes of thiobarbituric acid-reactive substances were recorded as additional oxidative markers for emulsions Results showed an Increase in oxidation as pressure was increased especially at 650 MPa Lipid oxidation rates that were more pronounced for HHP-treated samples can be correlated to measured dissolved oxygen that was also higher HHP did not seem to have an effect on emulsion droplet size The addition of Majorana syriaca (200 ppm) ethyl acetate extract led to protection against lipid oxidation under HHP and atmospheric conditions 20 9-38 7% and 28 9-43 2% respectively It was observed that the antioxidant effect of M syriaca extract under HHP was weaker (C) 2010 Elsevier Ltd All rights reserved	en
