Phycocyanin dosage

The phycocyanin dosage allows the quantification of this natural pigment with antioxidant properties, extracted from spirulina and other cyanobacteria.

This analysis is crucial for:

• Control the quality of spirulina powders or extracts
• Check the active ingredient content in food supplements
• Evaluate the stability of colored formulations
• Meet regulatory or marketing requirements (antioxidant claims)

It is part of a quality approach for manufacturers of nutraceutical, cosmetic or food products claiming a guaranteed phycocyanin content.

Methodology

Phycocyanin is analyzed by different techniques depending on the expected precision and the matrix:

• Spectrophotometry : measurement at 620 nm for rapid estimation
• High-performance liquid chromatography (HPLC) : more specific dosage, ideal for complex extracts
• LC-MS (HPLC-mass spectrometry coupling): for trace analyses or in the presence of interferents

The method chosen will depend on the type of product to be analyzed (raw powder, purified extract, capsule, drink, cosmetic, etc.).

Frequently analyzed matrices

• Spirulina powders
• Liquid or concentrated extracts
• Capsules, tablets, sachets of food supplements
• Functional drinks, smoothies
• Algae-based cosmetic products

Industrial applications

• Nutraceuticals : justification for the intake of natural antioxidants
• Sports nutrition : formulation of boosters or detoxifiers
• Natural cosmetics : gentle coloring and antioxidant action
• Food industry : natural blue-green coloring, alternative to synthetic colorings
