Research Progress on the Antioxidation of Edible Vegetable Oils

Abstract

Edible vegetable oils could provide energy, essential fatty acids and various micronutrients required in the body. However, vegetable oils, being rich in unsaturated fatty acids, are susceptible to oxidation to produce a series of oxidation products that are harmful to health after consumption, due to environmental factors during processing and storage. Therefore, this paper introduced the causes of oxidation in edible vegetable oils, the mechanism of lipid autoxidation, the main oxidation pathways and the hazards of oil oxidation, and the research progress of antioxidation on edible vegetable oils were also reviewed, including low-temperature storage, gas-conditioned storage and adding single or combined antioxidants. Meanwhile, the current problems on the lipid oxidation and the antioxidant measures in edible vegetable oils were discussed. This work could be expected to provide some references for the researches focusing on the oxidative stability of edible vegetable oils.
