Ot. Kasaikina et al., THE INHIBITORY ACTIVITY OF NATURAL PHENOLIC ANTIOXIDANTS IN THE OXIDATION OF LIPID SUBSTRATES, Russian chemical bulletin, 46(6), 1997, pp. 1070-1073
The suppression of the oxidation of triglyceride and methyl esters of
lard and olive and sunflower oils by additives of natural phenolic aci
ds (hydroxy and methoxy derivatives of para-hydroxybenzoic and cinnami
c acids) at 100 degrees C was studied. The rate constants of the inter
action of these acids with peroxyl radicals in the oxidation of cumene
at 60 degrees C were determined by the chemiluminescence method. Caff
eic acid is the most efficient lipid antioxidant, exceeding ionol and
alpha-tocopherol.
