Spirulina Extract

Spirulina extract is a vibrant blue or green colorant derived from spirulina, a type of blue-green algae. The algae are cultivated, harvested, and then processed to extract the natural pigments, primarily phycocyanin, which gives the extract its color.

Spirulina extract is used as a natural food coloring, offering alternatives to synthetic dyes. It is commonly found in confectionery, dairy products, beverages, and baked goods where a bright, natural blue or green hue is desired.

Spirulina extract is generally recognized as safe (GRAS) by the FDA for use as a food coloring. JECFA has evaluated spirulina extracts and established specifications for their use. While generally considered safe, some individuals may experience mild digestive upset. Research into its potential health benefits, such as antioxidant properties, is ongoing, but it is not approved as a medical treatment.
