Product Introduction:
Phycocyanin is an extract of spirulina. As a food raw material, it is obtained from spirulina through gentle physical processes such as concentration, centrifugation, and filtration. Only water is added as an auxiliary agent throughout the entire process, making it a very safe and healthy natural blue pigment.
Phycocyanin is one of the rare plant-based proteins in nature, which is well-aligned with current trends such as plant-based products, plant proteins, and clean labels. It is rich in high-quality protein and 8 essential amino acids required by the human body. As a micronutrient that the human body can more easily recognize and absorb, it has extremely high nutritional value and is thus vividly known as the "diamond of food".
Physicochemical Properties of Phycocyanin:
Phycocyanin generally exists as blue granules or powder. It is a protein-bound pigment, so 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.
