Color of vegetable oils is attributed to minor oil components present in a very small concentration, such as tocopherols, carotenoids and other pigments. These components were formed to undergo oxidation during oil storage which ultimately caused oil decolorization (Daniel, 1979). As Effect of antioxidants on the oxidative stability of anti oxidation vegetable oil storage oil tankmay be suitable for long-term storage stability tests on biodiesel, standard test methods ASTM D 4625 (Diesel Fuel Storage Stability at 43 8C) and D 2274 (Oxidation Stability of Distillate Fuel Oil [Accelerated Method]) are not well suited for rapid monitoring or spot-checking for effects of oxidation on biodiesel fuel quality [22,23,29].Enhancing oxidative stability and shelf life of frying anti oxidation vegetable oil storage oil tankThe oil samples were heated to 400oF in a bench top fryer.
