USE OF THE ORAC-PYROGALLOL RED/ORAC-FLUORESCEIN RATIO TO ASSESS THE QUALITY OF ANTIOXIDANTS IN CHILEAN WINES

, 2011
We have recently proposed that ORAC (Oxygen Radical Absorbance Capacity) methods employing fluorescein (ORAC-FL) and pyrogallol red (ORAC-PGR) as target molecules could be considered as complementary indexes.

Perspectives in biomedicine: Superfoods and antioxidant power classification

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The market value of natural food antioxidants will double to 8 billion USD by 2033, driven by a global consumer demand for ‘clean label’ products and proactive wellness solutions. However, the industrial application and health labelling (commercial brands) of these compounds remain severely constrained by inconsistent analytical methods.

Antioxidant Capacity of Pure Compounds and Complex Mixtures Evaluated by the ORAC-Pyrogallol Red Assay in the Presence of Triton X-100 Micelles

Molecules, 2010
The protective effect of different antioxidants and complex mixtures on the consumption of pyrogallol red (PGR) induced by peroxyl radicals was studied in the absence and presence of Triton X-100 micelles. The presence of micelles decreased significantly

Antioxidant Capacity of Free and Peptide Tryptophan Residues Determined by the ORAC (Oxygen Radical Absorbance Capacity) Assay Is Modulated by Radical-Radical Reactions and Oxidation Products

Foods, 2023
The ORAC (Oxygen Radical Absorbance Capacity) assay is commonly employed for determining the antioxidant capacity of bioactive peptides. To gain insights into the meaning of this index for peptides containing a single Trp, we studied the consumption of ...

Use of predictive tools for the analysis of bioactive compounds in Crocus sativus L. flowers

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Crocus sativus L. (saffron) flowers have high bioactive potential because of their content of crocins, safranal and phenolic compounds. The development of predictive models based on near‐infrared (NIR) spectroscopy and partial least squares regression to estimate the antioxidant capacity of saffron flower, evaluated using oxygen ...

Dietary melatonin and its benefits on cardiovascular disease

British Journal of Pharmacology, EarlyView.
Cardiovascular disease remains the leading cause of mortality globally, with a disproportionate burden in low‐ and middle‐income countries. Melatonin, a hormone primarily produced by the pineal gland, exhibits notable antioxidant, anti‐inflammatory and immunomodulatory properties that may confer cardiovascular benefits.
