Study on Oxidation Stability of Algae Oil

The peroxide value, content of malondialdehyde were selected as evaluation index to meusure the oxidation stability of algae oil. In this study, we investigated the effect of the temperature, light, air and metal ions on oxidation stability of algae oil. The results showed that higher was the temperature, much lower was the oxidation stability of oil; Light and oxygen both greatly promoted the oxidation of the oil; the order of the influence for metal ions to the oxidation stability was:Cu2+>Zn2+>Fe2+. Hence, we get that we should produce or store the oil under the condition that out of light, air, metal ions and kept at lower tempreture.
