ORAC (Oxygen Radical Absorbance Capacity)

What is measured:

Ability of a substance to subdue oxygen free radicals in vitro "total antioxidant capacity"

Type of method:

Spector fluorometric, performed by an outside lab (automated), based on the time-dependent decrease in the fluorescence of the B-PE indicator protein.

  • Free-radical generating system: AAPH
  • Sensitive target of the free radical attack: B- or R-PE
  • Quantification: area under the curve (combines both inhibition percentage and the length of inhibition time of free radical action by an antioxidant into a single quality)

Standard:

Trolox (water-soluble analog of vitamin E)
