| Abstract: | The suppression of the oxidation of triglyceride and methyl esters of lard and olive and sunflower oils by additives of natural
phenolic acids (hydroxy and methoxy derivatives ofpara-hydroxybenzoic and cinnamic acids) at 100 °C was studied. The rate constants of the interaction of these acids with peroxyl
radicals in the oxidation of cumene at 60 °C were determined by the chemiluminescence method. Caffeic acid is the most efficient
lipid antioxidant, exceeding ionol and α-tocopherol.
