PHYCOCYANIN comes from the Greek “phyco” meaning algae and “cyan” meaning blue.
Phycocyanin belongs to the phycobiliprotein family, which can be found in several microalgae (e.g. the orange phycoerythrin of Porphyridium cruentum), and comprises a high-molecular-weight protein component featuring the chromophores responsible for its colour. The bilin group (phycobilin) in phycocyanin is extremely close to the bile pigments in humans (bilirubin) and haemoglobin, the fundamental component of blood. Phycocyanin is a water-soluble protein and can be found in high concentrations in aqueous extracts, because it is the most abundant pigment in spirulina (15 % of the fresh weight).
Phycocyanin: a natural colorant
With its colorant properties, phycocyanin is currently one of only a handful of natural blue colorants. The FDA (Food Drug Administration) has allowed phycocyanin to be used as a blue food colouring agent since 2013.
But phycocyanin’s attributes are not restricted to its blue colouring properties. Scientific literature and a number of in vitro and in vivo experiments performed by Nantes Hospital in collaboration with AlgoSource have revealed several other properties (you can read this article for better knowledge on phycocyanin). Then, end of 2016, AlgoSource has launched a Clinical Trial in human to give a better idea of the potential antioxidant status of our phycocyanin-rich extract call Spirulysat®.
