100% Self-Grown Raw Materials · E163 Anthocyanins
Extracted from Raphanus sativus L. grown on Mingnan Bio's 100% self-owned plantations in China. Featuring industry-leading color value of 93 E(1%, 1cm, 520nm), customizable absorption peak wavelengths (λmax 470–550nm), and innovative Purple Radish extracts. Exported globally via Sunyuan (Hong Kong).
Scientific Overview
Radish Red is a pure natural, water-soluble anthocyanin pigment derived from Raphanus sativus L. roots. Unlike standard berry anthocyanins, radish anthocyanins are predominantly acylated pelargonidin glycosides, offering significantly superior heat and light resistance.
Through directional breeding, Mingnan Bio has successfully cultivated proprietary purple radish cultivars (Proprietary Cultivars) rich in high anthocyanin content and high-acylated structures. Combined with a gentle physical extraction process, we deliver natural pigment solutions offering exceptional thermal stability and vibrant purple-red hues.
Cultivated on Mingnan Bio farms
Instant dissolution in beverage systems
Elevated heat & retort stability
Zero synthetic dye blending
100% Self-Owned Farm-to-Factory Integration
Mingnan Bio operates 2000+ mu of dedicated radish plantations in China. Through standardized agricultural and quality management, we exert maximum control over pesticide residues. Before every shipment, we attach a batch-specific pesticide residue test report issued by an authoritative third-party testing laboratory. In the factory, extraction uses exclusively food-grade ethanol solvent.
Spectrum Engineering
By cultivating specialized radish cultivars, Mingnan Bio provides exact maximum absorption peak values to match your specific target shade requirements under spectrophotometric analysis.
Flagship Grade (Color Value 93). Bright strawberry & cherry red. Excellent acid stability. The industry standard for beverages and confectionery.
Deep ruby red profile with longer wavelength absorption. Perfect for meat alternatives, berry jellies, and fruit preparations.
Purple Strain Variety. Shorter wavelength absorption delivering natural violet-purple tones for functional beverages and candies.
Because Mingnan Bio breeds and cultivates 100% of its own radish raw materials in China, our agricultural scientists have developed 5 distinct Red Radish cultivars and 2 Purple Radish cultivars.
Each variety produces specific acylated anthocyanin molecular structures, yielding tailored maximum absorption peaks (λmax from 470nm to 535nm). This allows food and beverage formulators to achieve exact target shades—from bright strawberry red to royal purple—without synthetic dye blending.

Technical Application R&D
Our application team works directly with your food scientists to evaluate pigment reactions under different acidity, alkalinity, and thermal processing cycles.
At pH 2.0 - 4.0, radish anthocyanins form flavylium cations, yielding intense bright red shades. At pH 4.5 - 5.5, quinonoidal bases yield soft purple-red tones.
Due to high di-acylation in our radish cultivars, pigment retention exceeds 95% under standard pasteurization and UHT conditions, maintaining color strength without browning.
We offer custom matrix matching, shade tuning, dosage calculation, and light stability testing. Contact Sunyuan HK to request custom sample batches for your formulation.
