Standardized High-Active Anthocyanins (1%-25%): Strictly extracted from premium European bilberry fruit (Vaccinium Myrtillus L.) using gentle thermal control, providing standardized anthocyanins (1%–25% by HPLC/UV) for verified antioxidant and free radical scavenging activity.
Benchmark Ingredient for Eye Health & Microcirculation: Rich in natural anthocyanins and polyphenolic compounds, widely recognized for relieving eye fatigue, improving night vision, promoting ocular microvascular circulation, and supporting cardiovascular wellness.
Pleasant Flavor Profile & Excellent Water Solubility: Retains the natural deep purple-red color and mild tart flavor profile of fresh bilberries with rapid, complete solubility and clean taste—making it easy to mask without disrupting finished formulation flavor.
Gummy-Grade & Low-Hygroscopic Customization: Engineered with low hygroscopicity and high powder fluidity to solve sticky matrix, moisture absorption, and gelation degradation issues in functional gummy, tableting, and hard capsule lines.
As a specialized bulk botanical extract supplier, KEEP INGREDIENTS supplies high-grade bilberry extract engineered for dietary supplements, functional foods, and beverage formulations. European bilberries (Vaccinium Myrtillus L.) are globally celebrated for their significantly higher concentration of natural anthocyanins and polyphenolic compounds compared to standard blueberries. Our advanced refining processes deliver standardized bilberry extract anthocyanins, ensuring verified bioactivity and batch-to-batch stability.
To satisfy the stringent processing demands of functional gummies and instant beverage mixes, we have optimized the powder's particle flow and reduced hygroscopicity. Our water-soluble bilberry anthocyanins for beverages dissolve rapidly and completely in ambient water to form a clear, natural solution while delivering targeted functional performance.
We supply a comprehensive portfolio of bilberry raw materials to match diverse R&D and formulation requirements:
Standardized Active Extracts: Bilberry Extract 1%-25% Anthocyanins (Anthocyanins / Anthocyanidins by HPLC / UV)
Full-Spectrum Ratio Extracts: Bilberry Extract 10:1 (Custom extraction ratios available upon request)
Natural Fruit Powder Line: Pure Bilberry Fruit Powder / Water-Soluble Bilberry Juice Powder
Precise Standardization of Active Compounds
Available in standardized concentrations from 1% to 10% up to 25% anthocyanins (tested by HPLC/UV), preserving natural bioactive integrity through controlled extraction temperatures.
Gummy & Beverage Processing Optimization
Engineered specifically through physical modification to lower moisture uptake and avoid matrix degradation or sticky production runs—making it a smooth-processing ingredient for functional gummy manufacturing.
Eye Health & Ocular Microcirculation Support
Packed with active bilberry polyphenols and bioflavonoids to help relieve screen-induced eye fatigue, enhance night visual acuity, and support healthy ocular capillary blood flow.
Clean Flavor & Rapid Water Solubility
Preserves the natural mild tartness of the fruit without harsh bitterness or astringency, dissolving quickly in ambient water without floating particles or clumping.
To resolve practical manufacturing challenges faced by formulators and B2B buyers, our bilberry extract powder undergoes technical physical optimizations:
Thermal Stability & pH Adaptability
Anthocyanins are naturally sensitive to heat and pH variations. Our refined extraction process enhances thermal stability, ensuring high active retention during pasteurization or thermal processing. In acidic environments (pH 2.5–4.5), such as fruit juices and gummies, it maintains a brilliant and stable dark red to violet hue.
Anti-Hygroscopic & Anti-Caking Performance
Unprocessed botanical extracts often absorb ambient moisture rapidly, leading to clumping and active degradation. Our low-hygroscopic processing significantly lowers moisture uptake, preventing hopper clogging during milling, blending, and hard capsule filling.
Flavor Masking & Low Astringency
By removing unwanted tannins and bitter macromolecular compounds, our extract preserves a clean, mild fruit acidity. It blends seamlessly with natural fruit flavors and acidulants without disrupting the finished taste profile.
Functional Gummies & Chews: Ideal for eye protection gummies and antioxidant chews, effectively preventing sweating, oil bleeding, or structural softening.
Sports Nutrition & Instant Beverage Mixes: Blends smoothly into post-workout hydration powders, antioxidant drink stick packs, and ready-to-drink functional beverages.
Eye Health & Anti-Aging Supplements: Encapsulated or compressed into tablets alongside lutein, zeaxanthin, astaxanthin, or vitamin C for synergistic vision benefits.
We maintain strict quality management protocols to ensure every batch of bilberry extract complies with global regulatory and safety standards:
Rigorous Heavy Metal & Pesticide Testing: Tested via ICP-MS to ensure heavy metals (Lead, Arsenic, Cadmium, Mercury) and pesticide residues comply fully with EU and USP pharmacopeia thresholds.
Botanical Species Authenticity: 100% derived from authentic Vaccinium Myrtillus L. fruit with zero synthetic colorants or adulteration with cheaper anthocyanin sources.
Certified Manufacturing Facilities: Produced in cGMP, ISO22000, and HACCP-certified facilities, with Halal and Kosher documentation available upon request.
Note: The parameter standards below represent our highest standard specification (25% Anthocyanins by HPLC) as an example. We provide batch-specific COAs for all specifications (1%-25% Anthocyanins, 10:1 Ratio Extract, or Fruit Powder). Please contact our sales team for custom specifications or sample requests.
