Description

Spirulina Blue Color (Phycocyanin) is derived from Spirulina platensis, a microscopic blue-green algae cultivated under controlled, pollution-free conditions. Spirulina is rich in proteins, essential amino acids, vitamins, and minerals, and is recognized as one of the most nutritious and sustainable natural sources on Earth.
Our Spirulina cultivation base spans 60,000 acres of non-polluted, organic-certified land, ensuring raw materials are free from contaminants, heavy metals, and pesticide residues. The entire production process—from cultivation, harvesting, and drying to extraction—is managed under stringent food safety standards (ISO9001, FSSC22000).

Extraction and Purification Technology
Phycocyanin is extracted using cold-water enzymatic extraction and membrane filtration technology to preserve its bioactivity and natural protein structure. This gentle, solvent-free process ensures high purity, excellent color intensity, and superior solubility.
The pigment is then freeze-dried into a stable blue powder that maintains its vivid color and functionality, suitable for both liquid and powder formulations.

Chemical Composition and Structure
Spirulina Blue consists mainly of phycocyanin, a pigment-protein complex that belongs to the phycobiliprotein family. It is composed of a chromophore called phycocyanobilin, covalently linked to apoproteins. This unique molecular structure gives it a strong absorption peak around 620 nm, resulting in its intense natural blue hue.
Apart from its coloring ability, phycocyanin is also a biologically active compound with antioxidant, anti-inflammatory, and immune-supporting properties, making it a popular ingredient in health supplements and functional beverages.
