USDA Database for the Oxygen Radical Absorbance Capacity ...

Oxygen Radical Absorption Capacity (ORAC) assay measures the degree of inhibition of peroxy-radical-induced oxidation by the compounds of interest in a chemical milieu. It measures the value as Trolox equivalents and includes both inhibition time and the extent of inhibition of oxidation.

ORAC Assay for the determination of antioxidant capacity ...

antioxidant capacity of a substance is the oxygen radical absorbance capacity (ORAC) assay [3]. It is based on the inhibition of oxyradical-induced oxidation of 2,2’-azobis-(2-methylpropionamidine) dihydrochloride (AAPH) by substances with antioxidant properties. Peroxyl radicals produced in a
