Phycocyanin Food Additive from Spirulina for Blue Beverage Coloring

Ingredient profile

Blue Coloring and aqueous formulation define the formulation focus of Phycocyanin. Phycocyanin is a natural blue pigment-protein complex extracted from Arthrospira platensis (spirulina) and is one of the very few natural blue colorants available for food use.

Formulation characteristics

The pigment-protein complex provides a cyan-blue shade for the application examples described in the source. Color selection should be based on the final product matrix.

Water-soluble preparations are described for aqueous formulations. Blending with a suitable yellow pigment is identified as an option for developing green shades.

Color value and phycocyanin purity are separate grade considerations in the source. Specify both in the written specification instead of inferring them from the brightness of a photograph.

For Phycocyanin, the practical comparison is between blue coloring and the expected aqueous formulation result in the same recipe. Review blue pigment-protein complex sensitive to processing conditions alongside the intended use. A sample trial should record appearance, mixing behaviour and stability through the planned process. The useful acceptance criteria depend on the finished formulation rather than on a powder photograph alone.

The source describes the following presentation choices: water-soluble pigment; exact color value and grade to be specified. Specify the requested composition and physical form in the purchasing specification. For a product intended for beverages, evaluate compatibility with the other ingredients and with the actual storage conditions. The ingredient name is only the starting point of that comparison.

Applications

The application examples include beverages, confectionery, ice cream, desserts and bakery decoration. The relevant preparation should be selected for the intended matrix rather than assuming every described form is interchangeable.

Ingredient details

Handling and storage

Phycocyanin is heat- and light-sensitive and is best used in cold-processed, neutral to mildly acidic applications; verify stability in the final formulation.

Store refrigerated or in a cool, dry and sealed place, away from direct sunlight and high temperature to prevent denaturation and color loss.
