Antioxidants in lipid foods and their impact on food quality

Abstract. In bulk methyl linoleate and corn oil triglycerides, Trolox was a better antioxidant than a-tocopherol, but the opposite trend was observed in the corresponding oil-in-water emulsions. On the other hand, Trolox was a better antioxidant than a-tocopherol in both bulk and emulsified linoleic acid.
