Method Description
Polyphenols are a diverse group of antioxidant compounds including flavonoids, phenolic acids, and tannins found throughout the plant kingdom. Total polyphenol content is measured to support antioxidant claims on food and supplement labels, as these compounds are associated with various health benefits and product shelf-life stability. The Folin-Ciocalteu method measures total reducing capacity attributable to phenolic compounds, with results expressed relative to gallic acid standards.
