Spirulina C-Phycocyanin 25% Powder | Natural Blue

EarthHue Cyano-Blue 140 is a high-purity C-phycocyanin powder extracted from the cyanobacterium Arthrospira platensis (commonly known as Spirulina), standardized to 25% phycocyanin content. Phycocyanin is a blue pigment-protein complex that is one of the very few natural sources of a true, clean blue color — a shade notoriously difficult to achieve from nature without chemical modification.

As consumer demand for natural colors intensifies and synthetic blues such as FD&C Blue No. 1 (Brilliant Blue) face increasing scrutiny, Spirulina-derived phycocyanin has emerged as the leading natural blue alternative. Its bright, vivid blue performs exceptionally well in neutral-pH applications and can be blended with yellow colorants (such as lutein or beta-carotene) to create natural greens, or with red pigments to produce purple tones.

EarthHue Cyano-Blue 140 is widely used in functional beverages, smoothie mixes, ice cream, frozen desserts, confectionery coatings, and dietary supplement capsules and gummies. Its GRAS status (FDA) and EU E164 approval make it suitable for a broad range of food and beverage categories across North America, Europe, and Asia-Pacific markets.

The product is manufactured using a gentle water extraction process that preserves protein structure and color intensity, followed by low-temperature spray drying. Each batch is tested for phycocyanin purity ratio (A620/A280), heavy metals, microcystins, and microbial counts. It is non-GMO, vegan, and free from synthetic carriers.

For product developers who need a credible, regulation-ready natural blue — or a foundation for custom natural green and purple blends — EarthHue Cyano-Blue 140 is the Spirulina-based standard.
