Product source and process advantages
Plant source and production
Core raw materials: Select high-quality black rice (Oryza sativa L. var. indica) from Northeast China, Jiangsu and other places, using non-GMO varieties, no pesticide residues in the planting process, and traceable throughout the process.
Production process:
Extraction technology: Acid ethanol extraction combined with ultrasonic assisted extraction to efficiently extract anthocyanins, then purified by resin adsorption, low-temperature concentration and spray drying, color value ≥50 (E¹% 520nm)
Stability optimization: Microencapsulation technology enhances light resistance (UV irradiation 12 hours retention rate > 85%) and heat resistance (80℃/2 hours without fading), suitable for pH 2-8 environment.
Sustainability: Waste residue is converted into feed raw materials, resource utilization rate reaches 95%, and passed ISO 14001 environmental certification.
Quality certification
International certification: ISO 9001, HACCP
National standards: GB 2760-2014 "Standards for the use of food additives", GB 1886.336-2021 "Food Additives Black Rice Red"
Safety testing: Lead <0.05ppm, Arsenic <0.01ppm, Total colony count ≤1000 CFU/g, COA and HPLC spectrum are provided for each batch.
Scientific definition and core characteristics
Chemical definition: Black rice red (CAS number: 581-64-6) is a water-soluble anthocyanin pigment, the main active ingredient is cyanidin-3-glucoside, molecular formula C₂₁H₂₁O₁₁.
Physical and chemical properties:
Appearance: Dark purple powder (80-200 mesh), easily soluble in water and ethanol, the solution is transparent red to purple
Stability: Strong acid resistance (stable at pH 2-5), easy to turn blue in alkaline environment (pH＞7), need to be stored away from light
Safety: LD₅₀＞10g/kg (actual non-toxic level), no teratogenicity and genotoxicity.
Functional characteristics:
High-efficiency coloring: Absorbance (520nm) ≥1.2 (1000 times dilution), adjustable color tone (pink to dark purple)
Health benefits: Antioxidant activity (ORAC value 12,000 μmol TE/g), anti-inflammatory and cardiovascular protection
Verified efficacies and application scenarios
Food industry coloring
Broad-spectrum applications:
Acidic beverages: Fruit juice, fruit-flavored water (best color development at pH 3-5)
Baked goods: Red velvet cake, cookies (baking temperature ≤180℃);
Dairy products: yogurt, ice cream (addition amount 0.01%-0.1%)
Dairy products: Yogurt, ice cream (addition amount 0.01%-0.1%).
Compounding scheme: Compound with gardenia blue to produce purple, or mix with curcumin to produce orange-red, suitable for holiday-limited products
Health function development
Functional foods: Antioxidant capsules, eye protection tablets (addition amount 0.5%-2%)
Health products:Oral liquid formula to assist in lowering blood pressure and improving microcirculation.
Cosmetics and medicine
Natural colorant: Red base material for lipstick and blush, safe and non-irritating
Anti-aging ingredients: Added to essence and mask to synergistically fight free radicals
