Product Introduction:

Phycocyanin is an extract of spirulina. Phycocyanin E30 contains no auxiliary materials and is extracted through gentle processes such as concentration, centrifugation, and filtration. Only water is added as an auxiliary agent throughout the entire process.

After three years of research, Binmei has conducted more than 270 laboratory experiments and over 100 small-scale workshop production trials. Finally, it has overcome technical challenges and successfully produced 100% pure Phycocyanin E30.

Phycocyanin is an important light-harvesting pigment protein contained in spirulina, composed of open-chain tetrapyrrole compounds and apoproteins bound via thioether bonds.

Typically, phycocyanin exists in the form of a hexamer (αβ)₆. The α-subunit contains 1 phycocyanobilin (PCB) and has a molecular weight of 18.5 kDa, while the β-subunit contains 2 PCB groups and has a molecular weight of 20.5 kDa. Under neutral conditions, when phycocyanin is excited by light at 635 nm, its maximum fluorescence emission spectrum peak is at 650 nm, showing red fluorescence.

Phycocyanin generally appears as blue granules or powder. As a protein-bound pigment, it shares the same properties as proteins, with an isoelectric point of 3.4. It is soluble in water but insoluble in alcohols and oils. It is unstable to heat, light, and acids: it remains stable under weakly acidic to neutral conditions (pH 4.5–8), precipitates under acidic conditions (pH 4.2), and can be decolorized by strong alkalis.
