A deep analysis of multi-stage extraction, membrane filtration, and nano-encapsulation technologies solving sediment formation and bitter tannin astringency.
Traditional thermal evaporation degrades thermolabile compounds such as phycocyanin biliproteins and betanins. Our manufacturing facility employs sub-atmospheric vacuum evaporating systems operating below 45°C. This prevents thermal caramelization, retains native pigment chromophores, preserves active functional groups, and preserves solubility velocity in cold liquids.
Purification using non-ionic synthetic polymeric adsorbents separates primary active molecules (polysaccharides, polyphenols, anthocyanins) from insoluble plant fats, structural lignins, and insoluble waxes. This step removes heavy sediment precursors, providing crystal-clear aqueous solutions (Nephelometric Turbidity Units < 2.5 NTU) suited for clear RTD functional beverages.
Fine botanical dusts (>300 mesh) often form hydrophobic agglomerates or "fish-eyes" when introduced into water. Our secondary agglomeration process modifies individual powder particle morphology into porous micro-granules. Surface tension drops instantly upon contact with liquid, enabling free-flowing wettability and total dissolution without high-shear mixing.
How Mayfair, Soho, Fitzrovia, and Covent Garden beverage visionaries, boutique apothecaries, and wellness creators integrate our water-soluble botanical systems.
Boutique functional beverage producers throughout Soho require plant-based colorants that do not precipitate during pasteurization or carbonation. Our blue spirulina phycocyanin E25 and water-soluble red beetroot extract deliver radiant hues in canned botanical tonics, adaptogenic adapt-elixirs, and cold-brew infusions while maintaining total shelf stability without synthetic preservatives.
Bespoke skincare laboratories operating in Marylebone and Mayfair formulate topical serums requiring clear active solubilization. Our cosmetic-grade sodium copper chlorophyllin and alpha-arbutin integrate seamlessly into hyaluronic acid hydrogels and facial toners, delivering active phytochemical payloads without turbidity or oily separation.
High-end hospitality venues formulate colorful breakfast bowls, plant-based lattes, and viennoiserie. Using our 450-mesh butterfly pea flower and purple yam ube extracts allows instant color dispersal across barista oat-milks and cold foams without requiring chemical emulsifiers or leaving chalky grain residues on the palate.
Navigating consumer-driven clean labeling, synthetic dye phase-outs, and rapid bio-availability innovations in compliance with Great Britain regulatory frameworks.

Key regulatory, logistical, and technical considerations for procurement managers, formula developers, and quality control officers.
We deploy dual-stage membrane micro-filtration to eliminate long-chain plant waxes, cellular fiber, and insoluble fats. Combined with tailored vacuum spray-drying or freeze-drying crystallization, this process ensures the remaining active solids dissolve completely in cold water (4°C–15°C) without the need for high levels of carrier starch.
For stock powders (e.g., phycocyanin E25, matcha, sodium copper chlorophyllin), dispatch occurs within 48 to 72 hours via express air freight (DDP / DAP London Heathrow), reaching your facility within 5–7 business days. For bulk sea shipments, ocean transit into Felixstowe or Southampton takes approximately 24–28 days, backed by full customs clearance documentation.
Each production batch is released against strict specification ceilings aligned with GB/EU directives: Lead (Pb) < 2.0 ppm, Arsenic (As) < 1.0 ppm, Cadmium (Cd) < 1.0 ppm, Mercury (Hg) < 0.1 ppm. Microbiological plate counts are strictly managed (<1000 CFU/g, zero pathogenic Salmonella or E. coli detection). Third-party SGS verification reports accompany every production run.
Yes. We understand the formulation cycles of creative boutique brands across Central London. Most core water-soluble extracts have a flexible MOQ starting from just 1 kg.
