Black Rice (known botanically as Oryza sativa L.), historically referred to as "Forbidden Rice," has transitioned from a revered ancient grain to one of the most commercially significant raw ingredients in the global health and wellness market. The commercial extraction of black rice targets its highly concentrated pigment layer, which is exceptionally rich in natural flavonoids—specifically Anthocyanins.
As international consumer demand shifts heavily toward clean labels, natural food colorants, and active anti-aging components, global B2B procurement of standardized Black Rice Extract has surged. Industrial manufacturers rely on the standardized presence of active marker compounds like Cyanidin-3-Glucoside (C3G) to formulate functional products that support cardiovascular integrity, metabolic wellness, optical health, and cellular longevity.
Standardized to deliver up to 25% Anthocyanins by UV-Vis, primarily comprised of Cyanidin-3-Glucoside (C3G), ensuring maximum antioxidant capacity.
Processed through specialized temperature-controlled drying techniques that preserve the structural integrity of temperature-sensitive anthocyanins.
100% water-soluble powder formulation ideal for clear beverages, functional cosmetic liquids, and instant nutrient mixes without sedimentation.
The nutritional efficacy of Black Rice Extract is direct evidence of its high concentration of polyphenolic compounds. The primary active component, Cyanidin-3-O-Glucoside, works as a potent scavenger of free radicals. Below is the typical industrial technical specification table for premium wholesale grades manufactured at our facility:
| Specification Parameter | Standard Range / Value | Testing Method |
|---|---|---|
| Appearance | Dark Purple to Deep Violet Fine Powder | Visual Inspection |
| Anthocyanin Content | 5% - 25% Min | UV-Vis / HPLC |
| Cyanidin-3-Glucoside (C3G) | 1% - 15% Min | HPLC Chromatographic Area |
| Loss on Drying | ≤ 5.0% | Direct Oven Gravimetric |
| Heavy Metals (Pb, As, Cd, Hg) | ≤ 10 ppm total (Pb ≤ 2.0ppm, As ≤ 1.0ppm) | ICP-MS |
| Solvent Residue | Methanol/Ethanol Free (Water Extracted Only) | GC-Headspace |
| Microbial Count | Total Plate ≤ 1000cfu/g; Yeast/Mold ≤ 100cfu/g | USP / AOAC Method |
The global demand for Black Rice Extract is accelerating across major geopolitical markets, including North America, the European Union, and the Asia-Pacific region. This growth is predominantly driven by two distinct consumer trends: the replacement of synthetic red and purple dyes (such as Red 40) with stable, plant-derived colorants, and the rapid expansion of the active longevity and metabolic health supplement sectors.
Large-scale manufacturers require continuous, predictable supply chains that can satisfy massive production runs. By choosing Chinese manufacturing facilities, global buyers gain immediate access to localized raw material cultivation, optimized production lines, and robust quality management programs. These factors protect global companies from shipping delays and guarantee consistent ingredient quality across production runs.
1. Agricultural Scale & Raw Material Traceability: China's fertile central and southern regions possess ideal climatic conditions for black rice cultivation. Our factories maintain direct partnerships with local agricultural cooperatives, securing the finest quality grains with high initial anthocyanin levels before the extraction process even begins.
2. Advanced Industrial Scaling & Efficiency: Equipped with industrial-grade continuous countercurrent extraction lines, Chinese factories optimize the output per metric ton of raw grain. This efficiency directly translates to competitive pricing for buyers without compromising purity or safety.
3. Certified Regulatory Compliance: Leading Chinese manufacturers maintain complete alignment with international standards, holding certifications including GMP, ISO, HACCP, Organic, FDA, Halal, and Kosher. This structural compliance ensures smooth regulatory clearance at customs and seamless integration into final products.

Our industrial Black Rice Extract is standardized primarily for total Anthocyanins (typically 25% by UV-Vis spectrophotometry) and Cyanidin-3-Glucoside (C3G, up to 15% using High-Performance Liquid Chromatography - HPLC). C3G is the primary active anthocyanin responsible for the extract's antioxidant properties and physiological benefits.
Anthocyanins are susceptible to heat degradation. We use low-temperature vacuum extraction alongside rapid spray-drying systems to minimize thermal exposure. This process preserves the raw materials' antioxidant potential, ensuring excellent stability when stored under cool, dry conditions.
Yes. Our extract is processed to remove insoluble starches and celluloses, yielding a highly refined powder that dissolves quickly and completely in water. It produces a clear, sediment-free liquid, making it ideal for clean-label functional beverages and liquid formulas.
Our standard MOQ for wholesale orders is 25 kg, packaged in double-lined food-grade bags within fiber drums. For custom specifications or trial runs, smaller evaluation quantities can be arranged. Typical lead times are 7 to 10 days from order confirmation to port delivery in China.
