◦ Science & Quality
When your formula demands the purest blue, demand a purity ratio.
C-Phycocyanin is the high-value blue protein-pigment complex inside Arthrospira platensis. Its value is determined by a single ratio — A620 (peak phycocyanin absorbance) divided by A280 (total protein absorbance). The higher the ratio, the higher the application tier.

◦ Our Extraction Process
Eight steps. Zero shortcuts.
Cultivation
Open-pond raceways at our South Indian cultivation facility with monitored pH, salinity, and biomass density.
Harvest & Wash
Cross-flow filtration removes excess media; biomass washed to <0.1% NaCl.
Cell Disruption
Controlled hydro-mechanical lysis to release intracellular phycocyanin without denaturing.
Extraction
Phosphate-buffer extraction at 4 °C — the gentlest viable extraction protocol.
Purification
Ultrafiltration + chromatography to lift A620/A280 from 0.7 → 3.0+.
Freeze-Drying
Lyophilisation under -60 °C / 0.01 mbar to preserve colour intensity and bioactivity.
QC & Release
NABL lab tests: HPLC, heavy metals, microbial panel, endotoxin (E30 only).
Export
Cold-chain logistics, USFDA-prior-notice ready, EU CHED documentation included.
