• Comparative evaluation of various total antioxidant capacity assays applied to phenolic compounds with the CUPRAC assay. (2007, methodology): “As an example of HAT−based assays, oxygen radical absorbance capacity (ORAC) assay [65] applies a competitive reaction scheme in which antioxidant and substrate kinetically compete for thermally generated peroxyl radicals through the decomposition of azo compounds such as ABAP (2,2’-azobis(2aminopro”

• Analytical Methods Used in Determining Antioxidant Activity: A Review (2021, methodology): “However, the use of β-phycoerythrin in antioxidant assays has shortcomings for some reasons: • β-phycoerythrin has large variability in reactivity to ROO•, leading to inconsistency in assay results; • β-phycoerythrin becomes photobleached after exposure to excitation light interaction with polypheno”
