Wholesale Premium Black Rice Extract Powder (Oryza Sativa L.)
High-Purity Cyanidin-3-Glucoside (C3G) ≥ 25% | Strict Regulation (EC) No 396/2005 Compliant Low Pesticide & Solvent Residues
Are you facing continuous technical barriers when formulating natural antioxidant supplements, functional beverages, or anti-aging clean-label products? While the global demand for plant-based anthocyanins is surging, many bulk botanical sourcing managers are repeatedly plagued by severe batch-to-batch active ingredient drifting, excessive pesticide residues breaking EU customs barriers, and harsh chemical solvent smells that ruin finished product organoleptic profiles. Low-grade black rice extracts often suffer from fast oxidative browning and poor water solubility, resulting in ugly precipitation in functional liquid bases.
Xi'an Green Spring Technology addresses these rigorous manufacturing pain points directly. Our industrial-grade bulk Black Rice Extract Powder is standardized to contain a guaranteed premium assay of Cyanidin-3-Glucoside (C3G) ≥ 25% (tested via precise HPLC). Utilizing our clean water-ethanol closed-loop extraction technology, we strictly control every production run to comply with the European Union Regulation (EC) No 396/2005, ensuring ultra-low pesticide residues and minimal solvent trace limits. The powder delivers excellent water solubility, superb thermal/light color stability, and zero chemical off-notes-making it the ideal choice for demanding global supplement and functional food formulators.
Advanced Manufacturing Technology & Process Advantages
- Guaranteed HPLC Fingerprint Standardization: We trace and stabilize the active ingredient matrix from raw crop to final milling. Every commercial batch delivers a reliable 25% threshold of Cyanidin-3-Glucoside (C3G), protecting your formula potency from sensory and clinical fading.

Industrial Product Applications & R&D Formulation Protocols
Due to the high concentrations of metabolic C3G fractions, our premium extract integrates easily into high-end health and retail food development blueprints:
Target: High-efficacy anthocyanin capsules.
Formulation Tip: Combine Black Rice C3G with Bilberry Extract or Lutein esters. The micro-mesh powder delivers superb flowability for high-speed automated encapsulation tooling.
Target: Liquid collagen or functional ready-to-drink (RTD) formulas.
Formulation Tip: Easily blended with Collagen Peptides. It dissolves crystal clear, maintaining a vivid berry-purple tone under acidic drink setups (pH 3.0–4.2).
Target: Zero synthetic dye candies, gummies, or yogurts.
Formulation Tip: Functions as a robust E-number alternative. Replaces artificial red/violet dye systems while giving nutritional antioxidant value.
Commercial Success Stories & Case Studies
Case 1: Overcoming EU Customs Rejections due to Pesticide Residues for a French Brand
The Hurdle: A Nutraceutical manufacturer in France faced heavy supply blockages after their local customs seized a batch of raw anthocyanin powders from another supplier due to unauthorized pesticide trace lines exceeding the stringent European EC396 rules.
The Execution: Green Spring stepped in and provided our standardized C3G ≥ 25% Extract Powder. Every metric was pre-certified by an independent Eurofins lab under Regulation (EC) No 396/2005 specifications.
✔ The Result: The client successfully cleared European customs gates with zero non-compliance alerts, ensuring uninterrupted manufacturing runs and retail line rollouts.
Case 2: Eradicating Precipitation in Nutricosmetic Anti-Aging Liquid Drinks
The Hurdle: A German beauty brand noticed ugly, dark granular sediment forming at the bottom of their anti-aging collagen shots when using raw botanical extracts, severely threatening consumer return rates.
The Execution: Our R&D team supplied our specialized ultra-soluble, fine mesh Black Rice Extract Powder, fully optimized via water-filtration processes to clear insoluble seed-coat fibers.
✔ The Result: The product achieved a completely homogeneous, brilliantly transparent purple liquid curve with zero precipitation across a 12-month shelf stability trial.
Industrial Quality Validation & Client Reviews
"Finding a stable supplier who can genuinely guarantee C3G ≥ 25% via HPLC while complying with EU EC396 rules was a major hurdle. Green Spring's material quality has been highly reliable over 3 separate container orders. The solvent residue levels are almost undetectable, which keeps our regulatory verification smooth."
- Dr. Aris M., Chief Innovation Officer Premium Eye & Vascular Supplement Brands (Italy)"Our organic clean-label functional gummies demand intense hue retention without chemical odors. This high-purity purple extract works brilliantly. Dissolves seamlessly at low temperatures and doesn't interfere with our delicate flavoring systems."
- Sarah G., Lead Formulation Engineer Organic & Functional Confectionery Corporation (UK)Frequently Asked Questions (Bulk Procurement & Technical Support)
A: C3G is the predominant, highly bioavailable active monomer within the anthocyanin family. Extensively documented for its powerful antioxidant capacities, it strongly supports vision preservation, radical scavenging, anti-inflammatory pathways, and modern metabolic conditioning profiles.
A: We strictly control the primary farming origins of our raw black rice grain. Post-harvest matrices undergo advanced multi-stage water washing and processing via highly specific resin columns. This targets and strips out non-polar pesticide strings, easily surpassing European low-residue standards.
A: We exclusively utilize a clean, food-grade water and ethanol blend. No toxic aromatic hydrocarbons, chlorinated solvents, or methanol systems are permitted inside our cGMP processing building, keeping organic residue levels far below international regulatory limits.
A: Like natural anthocyanins, our powder acts as an organic color indicator. Under acidic formulation environments (pH 2.0–4.0), it displays a beautiful, highly stable deep red/violet-purple tone. In neutral matrix conditions (pH 7.0), it transitions into a darker blue/faded shade.
A: Our standard packaging configuration is 25kg double food-grade airtight poly-bags encased inside heavy-duty industrial cardboard fiber drums. The product carries a certified shelf life of 24 months when stored unopened away from direct heat, high moisture, and intense ultraviolet exposure.
