Dynamic pH-Responsive Spectrum

Standardized with highly concentrated, active anthocyanin molecules. It transitions effortlessly from a deep vivid blue at neutral pH, into striking violet and magenta tones when citric acids or citrus juices are added.

Thermostable Color Retention

Utilizes gentle low-temperature spray drying parameters to cross-link natural pigments. This prevents thermal structural breakdown during standard high-temperature short-time (HTST) pasteurization processes.

Flawless Instant Cold Solubility

Refined into an ultra-fine crystalline mesh that dissolves instantly in cold liquid solutions. It ensures a transparent, high-clarity color profile completely free from standard botanical specks or bottom sediment.

Functional Drinks & Teas

Provides sediment-free, clear blue coloration for premium cold-brew tea networks, ready-to-drink (RTD) botanical waters, clear wellness syrups, and innovative color-evolving sport shots.

Confectionery & Dairy

Excellent natural dye substitute for vegan gummies, gelatin fillings, ice cream bases, protein frostings, and hard-panned candies that require strong thermal stability and no color bleeding.

Clean Beauty & Skincare

Ideal for formulating natural azure face creams, botanical bath crystals, calming clear hair serums, and organic soaps leveraging the natural soothing properties of anthocyanin matrices.

"The cold solubility of the GSTE-BP-SOL grade is exceptional. It gives our functional waters an incredibly brilliant blue clarity without any gritty residue."

"Meeting European pesticide standards was our primary challenge with butterfly pea flower. This extract passes our laboratory screen comfortably batch after batch."

"We use the cosmetic grade for our facial serum ranges. The color-shifting function gives us a strong marketing advantage, and the heavy metal limits are perfectly safe."

Delivered in 25kg net weight industry fiber drums. Each drum is equipped with dual heavy-gauge moisture-proof polyethylene inner vacuum bags to completely secure the stable extract against air exposure and environmental humidity.

Keep enclosed within cool, dark, and thoroughly ventilated dry storage areas. Maintain warehouse temperatures strictly under 25°C (77°F) with humidity levels monitored under 60% to prevent natural pigment oxidation and clumping.

Distributed globally via climate-monitored sea vessels or expedited air cargo lines. Every single shipment batch is accompanied by comprehensive tracking documentation, safety data sheets (SDS), and laboratory certificates.

A: Raw butterfly pea flowers can vary heavily in shade due to seasonal rainfall. To guarantee uniformity, our factory utilizes standardized water extraction protocols and adjusts batches to meet strict spectrophotometric color-density specifications. This ensures that every delivery gives you the exact same blue hue intensity.

A: The color shift is driven by the structure of ternary anthocyanins, which alter their shape depending on the hydrogen ion concentration (pH) of the liquid. At a neutral pH (6.0–7.0), the color stays vivid blue. If you add acid components like lime juice to drop the pH below 4.5, it shifts into deep purple and magenta shades. It can easily be kept a stable blue by managing your base formula's pH with neutral buffers.

A: Butterfly pea flowers are prone to insects, leading many growers to over-apply chemicals. We manage our supply chain through audited, trackable farming cooperatives that follow strict, pesticide-restricted growing protocols. Every finished production batch undergoes thorough testing via GC-MS/MS to ensure complete compliance with EU EC No 396/2005 regulations.

A: Yes. Unlike raw crushed flower powders which leave fibrous plant particles floating on top or dropping to the bottom, our spray-dried extract is 100% water soluble. It dissolves quickly into liquids within 45 seconds, giving you a crystal-clear translucent blue appearance with absolutely zero residue.

A: While basic plant colorings can fade or turn brown under heat, our low-temperature concentration preserves the stable core flavonoid bonds. It easily handles standard high-temperature short-time (HTST) beverage pasteurization loops without significant color loss or browning, provided the fluid pH remains monitored.

A: Our advanced manufacturing plant holds complete global health certifications, including FSSC22000, ISO9001, and ISO22000 setup approvals. Each shipment comes complete with a technical file: batch Certificates of Analysis (COA), comprehensive multi-residual pesticide logs, heavy metal analysis, non-irradiation statements, and Kosher/Halal documents.

A: Our standard extract is highly hydrophilic and optimized for water-based mixtures. To disperse it uniformly inside pure anhydrous oils, lipsticks, or heavy balms, you will need to pre-mix it with a food-grade emulsifier or fluid surfactant matrix before blending it into your final oil phase.

A: Our bulk factory wholesale MOQ is one 25kg net weight fiber drum. For corporate R&D trials, pilot production approvals, and lab verification studies, we gladly offer complimentary 10g to 50g testing samples to verified business accounts and product formulation labs worldwide.
