Above this ratio the photo-antioxidant activity of the bound antioxidant falls off sharply. BPM, when used as an additive (without radical generator), has a photo- antioxidant activity similar to the commercial hindered piperidine, Tinuvin 770, at the same molar functional group concentration (see Table 1).

Antioxidant Property of Coffee Components: Assessment

Reaction mechanism of 2,2-diphenyl-1-picrylhydrazyl (DPPH) with antioxidant. R:H = antioxidant radical scavenger; R = antioxidant radical. Antioxidants react with free radicals by different mechanisms—hydrogen atom transfer (HAT) or single electron transfer mechanism (SET); or the combination of both HAT and SET mechanisms being primary examples.
