Black Rice Extract 20% C3G Powder (HPLC) | USP/EP Compliant

What is Black Rice Extract 20% C3G Powder?

Black Rice Extract 20% C3G Powder is a highly standardized natural colorant and functional nutrient derived from the anthocyanin-rich pericarp of non-GMO black rice (Oryza sativa L.). It is scientifically quantified via HPLC to contain a minimum of 20% Cyanidin-3-O-glucoside (C3G) and total anthocyanins. Formulated for industrial stability,this water-soluble botanical extract delivers exceptional antioxidant efficacy, serving as a clean-label alternative to synthetic purple and dark-red dyes.

Tecnología de primavera verde manufactures this premium ingredient using an eco-friendly water-and-ethanol refluxing technology that preserves molecular structural integrity. Operating strictly with purified water and food-grade ethanol, the process leaves zero toxic chemical solvent residues. The final ingredient is standardized into a dark purple to black powder featuring 100% rapid water solubility and a granulated, dust-free specification optimized for automated commercial blending lines.

Key Advantages

• Thermal & Process Stability: Eliminates natural pigment degradation during thermal sterilization. Standardized C3G molecules maintain over 95% retention rate under 90°C processing for 30 minutes, preventing fading or browning in high-temperature food and beverage production.

• Instant Cold-Water Dissolution: Solves the industrial hurdle of powder aggregation and mixing delays. Engineered micro-particles achieve 100% complete dissolution in cold water (15-20°C) within 30 seconds, leaving zero sediment, zero ring-formation, and yielding a crystal-clear purple solution.

• pH Discoloration Control: Counteracts the traditional instability of anthocyanins across varied acid matrices. The pigment structure remains strictly stable within the pH 3.0 to 6.5 range, delivering uniform, reliable color profiling for soft drinks, functional gummies, and dairy items.

• Clean-Label Compliance: Meets the strict regulatory shift away from synthetic azo dyes (E-numbers). Extracted via a clean water-and-ethanol reflux loop, this ingredient yields 100% chemical-carrier-free powder to satisfy the rigorous clean-label auditing of global premium brands.

• Batch-to-Batch Homogeneity: Mitigates formulation risks caused by fluctuating active levels in raw botanicals. Utilizing advanced HPLC-guided peak alignment, every industrial lot guarantees a strict deviation threshold of ≤2.0% for C3G potency, ensuring seamless replication in large-scale contract manufacturing.

  Technical FAQ

• Q1: How does Green Spring ensure batch-to-batch alignment for the 20% C3G specification under HPLC validation?
  A1: Our protocol utilizes standardized chromatographic peak alignment with specific reference standards. Every batch is extracted within a calibrated vacuum temperature loop to prevent thermal degradation of monomeric anthocyanins. This process maintains a strict C3G potency deviation threshold of ≤2.0% across all industrial contract manufacturing lots.

• 
  

• Q2: What formulation strategies prevent the discoloration of this 20% C3G powder in acidic liquid systems or when co-administered with ascorbic acid?
  A2: Cyanidin-3-O-glucoside maintains its stable flavylium cation structural form strictly within the pH 3.0 to 4.5 matrix. For beverage formulations co-administering Vitamin C, we recommend utilizing chelating agents or buffering salts to suppress oxidative degradation. This strategy ensures a color retention rate exceeding 95% during shelf-life degradation tests.

• 
  

• Q3: Does this USP/EP compliant extract fully satisfy the strict European maximum residue limits for polycyclic aromatic hydrocarbons and heavy metals?
  A3: Yes. Our botanical raw materials undergo strict mechanical husk separation before ethanol refluxing to minimize outer environmental contamination. Every shipment lot is validated via high-precision ICP-MS and GC-MS instrumentation to guarantee quantified metrics of PAH4 ≤ 50 ppb, Benzo(a)pyrene ≤ 10 ppb, and Lead (Pb) ≤ 1.0 ppm.
