www.orac-info-portal.deThe assay has been used to measure the antioxidant activity of foods. The method developed by Prior et al. (17) measures both hydrophilic (H-ORAC) and lipophilic ORAC (L-ORAC) for water soluble and fat soluble antioxidant compounds respectively. In addition to the ORAC assay, other common measures of antioxidant capacity (AC)

faculty.missouri.eduApr 26, 2005 · ORAC: General Chemistry. The ORAC assay is based upon the early work of Ghiselli et al. (10) and Glazer (11), as developed further by Cao et al. (12). ORAC measures antioxi-dant inhibition of peroxyl radical induced oxidations and thus reflects classical radical chain breaking antioxidant activity by H atom transfer (13).

neotec.co.ilantioxidant 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
