Spirulina concentrate

Spirulina concentrate is a vibrant blue or green pigment derived from a type of blue-green algae (cyanobacteria). This algae is cultivated in controlled environments, typically in large ponds or bioreactors, and then processed to extract and concentrate its natural colour compounds.

Manufacturers use spirulina concentrate primarily as a natural food colouring, providing intense blue and green hues. It is found in a variety of confectionery items like candies and jellies, as well as in ice creams and sorbets, where a visually appealing colour is desired.

Spirulina concentrate is authorised as a food additive in Great Britain and is listed on the Register of Food Additive Authorisations. EFSA has evaluated spirulina extracts. The European Food Safety Authority (EFSA) has established acceptable intake levels for spirulina extracts. It is generally considered safe when consumed within typical dietary levels found in foods.
