Total polyphenols refer to the collective measurement of phenolic compounds in plant-based foods and spices, including flavonoids, phenolic acids, tannins, and stilbenes. These secondary metabolites contribute to antioxidant capacity, color, flavor, and health benefits in spices like cloves, cinnamon, and oregano. Content is typically quantified as gallic acid equivalents (GAE) via Folin-Ciocalteu assay. They exhibit variable structures based on multiple hydroxylated aromatic rings, influencing bioavailability and bioactivity. In food science, higher total polyphenol levels correlate with enhanced oxidative stability and potential anti-inflammatory effects, though individual compounds vary widely in potency and solubility profiles.
