Description
A blended polyphenol extract drawing from multiple botanical sources including grape seed proanthocyanidins, green tea catechins, pomegranate ellagitannins, blueberry anthocyanins, and resveratrol. Standardized to total polyphenols by Folin-Ciocalteu assay and ORAC antioxidant capacity.
Dark red-brown to brown fine powder. Soluble in water with mild stirring. Characteristic polyphenol-complex aroma.
We supply polyphenol blend products from manufacturers in China holding ISO, Halal, Kosher, GMP and other certifications relevant to the product and production.
Common market formats include standardized 50% polyphenol, 75% polyphenol, and 90% polyphenol blends. Custom botanical source ratios are available on request to support specific finished-product positioning.
Bulk and reduced-MOQ shipments. Batch-level COA covering total polyphenols, individual marker compounds, ORAC value, microbiology, and heavy metals.
Introduction
Plant polyphenols are a structurally diverse class of secondary metabolites including flavonoids, phenolic acids, stilbenes, and tannins. Across the class, common functional features include phenolic hydroxyl groups capable of donating hydrogen atoms to free radicals, the chemical basis of antioxidant activity.
Multi-source polyphenol blends address the consumer-positioning advantage of combining widely recognized antioxidant botanicals into a single ingredient, supporting compact dosage forms and marketing simplification. Typical components include grape seed extract for proanthocyanidins, green tea extract for catechins (particularly EGCG), pomegranate extract for ellagitannins and punicalagins, and blueberry extract for anthocyanins.
Production is by separate extraction and standardization of each component botanical, followed by ratio-controlled blending to a target total polyphenol content and ORAC value. Spray-drying with food-grade carriers produces the finished powder.
The ORAC (Oxygen Radical Absorbance Capacity) value remains widely used in commercial polyphenol positioning despite the U.S. Department of Agriculture's removal of its ORAC database in 2012 due to concerns about in-vivo relevance. Modern marketing typically presents ORAC as a comparative laboratory measure rather than a clinical claim.
Regulatory framework treats individual polyphenol botanicals as established food supplement ingredients in major markets. Specific health claims related to antioxidant activity vary by jurisdiction and require regulatory authorization.
