This paper describes a study of the influence of extraction system (centrifugation and pressure system) on the chemical composition and sensory quality of Dan virgin olive oils produced in Syria. Analysis of the effect of the extraction system on the values of analytical determination revealed statistically significant differences (P≤0.05) in a few parameters only, mainly in antioxidant content and oxidative stability. The results appear to confirm the influence of the extraction system on the quality of Dan virgin olive oils.
