Botanical Source: Hibiscus sabdariffa L. (Roselle, Luoshen Flower, Jamaican Sorrel)
Used Part: Dried Fleshy Calyces (the protective sepals surrounding the flower)
Key Active Components: Rich in Anthocyanins (delphinidin-3-sambubioside, cyanidin-3-sambubioside), Flavonoids (gossypetin, hibiscetin), and Organic Acids (hibiscus acid, citric acid, malic acid, protocatechuic acid) .
Standardization: Available standardized to Total Anthocyanins (e.g., 5%, 10%, 20%) or Total Polyphenols .
Appearance: Fine, deep red to dark burgundy powder.
Flavor: Characteristically tart, tangy, and refreshing, similar to cranberry.
Solubility: Highly soluble in water; anthocyanins are pH-sensitive, displaying vibrant red hues in acidic conditions and shifting to blue/purple as pH increases.
Our process is optimized to gently extract and preserve the delicate anthocyanins and heat-sensitive organic acids:
Sustainable Sourcing & Authentication: Sourcing of premium, dried Hibiscus sabdariffa calyces from trusted agricultural partners, verified for species and quality.
Cleaning & Size Reduction: The calyces are carefully cleaned, inspected, and milled to a uniform particle size to optimize extraction efficiency.
Controlled Aqueous or Hydroethanolic Extraction: Utilizes purified water or food-grade ethanol at controlled, low temperatures to efficiently solubilize the target anthocyanins and polyphenols while minimizing thermal degradation .
Filtration & Clarification: The crude extract undergoes fine filtration and clarification to remove insoluble plant material and suspended solids, resulting in a vibrant, clear liquid.
Concentration & Purification: The clarified extract is concentrated under vacuum at low temperatures to preserve the sensitive anthocyanin profile. Advanced purification techniques may be employed to enrich specific bioactive fractions.
Standardization & Stabilization: The concentrated extract is analytically tested and blended to achieve a guaranteed, consistent level of anthocyanins or total polyphenols. Natural stabilizers may be added to protect color and bioactivity during shelf life .
Gentle Drying: The standardized liquid is spray-dried using low-heat inlet temperatures, often with a food-grade carrier (like maltodextrin or acacia fiber) to produce a stable, free-flowing powder that retains maximum color and potency .
Comprehensive Quality Verification: Each batch is analyzed via HPLC for anthocyanin profile, total phenolic content, color value, and safety parameters (heavy metals, microbiology).
