RELEVANCE OF SECONDARY PROCESSES IN ORAC VALUES OBTAINED EMPLOYING PYROGALLOL RED AS TARGET MOLECULE
Pyrogallol red (PGR) is readily bleached by peroxyl radicals . Addition of cinnamic acid derivatives (coumaric, caffeic, ferulic and sinapic acids), even at relatively high concentrations, barely protects PGR from bleaching, given very low ORAC (oxygen radical absorbance capacity) values. This lack...
