Jimenez-Escrig et al., 2001), and the oxygen radical absorption capacity (ORAC) (Cao et al., 1993; Ou et al., 2001; Prior et al., 2003). The ORAC assay is said to be more relevant because it utilizes a biologically relevant radical source (Prior et al., 2003). These techniques have shown different results among crop species and across laboratories.
Infrared (IR) spectroscopy is one of the most common spectroscopic techniques used by organic and inorganic chemists. Simply, it is the absorption measurement of different IR frequencies by a
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.
