Description
The polyphenol-enriched extract of plum fruit (Prunus domestica, including prune-type cultivars), containing anthocyanins, chlorogenic acid, neochlorogenic acid, and characteristic plum phenolics. Positioned for bone-health, digestive-wellness, and antioxidant supplement applications based on the well-documented effects of prunes on bone density and gastrointestinal motility.
Dark red to purple-brown free-flowing powder with characteristic mild fruity aroma. Highly water-soluble.
We supply food-grade Plum Polyphenols from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include 4:1 Standard Extract (the cost-effective baseline), 10:1 Premium Extract, 20:1 High-Concentration Extract, Total Polyphenols 30 percent / 50 percent / 70 percent (standardized grades), and Anthocyanin-Enriched grades at 5 percent and 25 percent anthocyanins for premium positioning.
Bulk and reduced-MOQ shipments. Batch-level COA covering total polyphenols (Folin-Ciocalteu), anthocyanin content, chlorogenic acid content, residual solvents, heavy metals, pesticides, and microbiology.
Introduction
Plums and prunes (dried plums) have been recognized as traditional foods supporting digestive regularity for centuries. The modern positioning of plum polyphenols as a bone-health ingredient is more recent, supported by a growing body of randomized controlled trials (primarily from researchers at U.S. and European universities) demonstrating improvements in bone-density markers in postmenopausal women consuming 50 to 100 grams of prunes daily.
Industrial production proceeds by aqueous extraction of plum or prune fruit, followed by membrane separation and adsorption-resin chromatography to enrich polyphenol content while removing the substantial sugar and organic-acid content of the source material.
Recognized as a permitted food ingredient by the U.S. FDA (GRAS for typical plum-fruit-derived polyphenol preparations), the European Food Safety Authority, and equivalent regulators worldwide.
Strategic positioning combines the emerging bone-health supplement category (the highest-margin commercial segment), digestive-wellness supplements (the traditional application), and broad antioxidant supplement positioning.
