Antioxidant Activity of Paprika Carotenoids¶
Overview¶
Paprika powder has an Oxygen Radical Absorbance Capacity (ORAC) of approximately 21,000 µmol TE/100 g (USDA database) — one of the highest among dried spices. The primary contributors are capsanthin, capsorubin, β-carotene, and phenolic compounds.
| Compound | ORAC Contribution | Mechanism |
|---|---|---|
| Capsanthin | ~45% | Singlet oxygen quenching (SOQ) |
| Capsorubin | ~15% | Radical scavenging |
| β-Carotene | ~20% | Peroxyl radical trapping |
| Phenolics | ~15% | Metal chelation + radical scavenging |
| Tocopherols | ~5% | Lipid oxidation chain breaking |
