Öz Automated analytical methods were developed for the quality control of olive oil, including the determination of acidity, peroxide value (PV), iodine value (IV), 2-thiobarbituric acid reacting substances (TBARS), iodine value (IV) and anisidine value (AV). The developed flow injection methods exhibit the following advantages: high analysis rates (20-100 h-1); full automation that results in increased precision and accuracy; low cost; low solvent consumption and elimination of chlorinated solvents, that renders the developed methods environmental friendly; low sample consumption (0.0012-0.2 ml per analysis); good agreement with time consuming official methods; and protection of reagents from light and atmospheric oxygen
