The Only Globally Approved Blue Natural Colorant

It is extremely challenging to replace patent blue (E131) or brilliant blue (E133) with natural blue colorants. Spirulina extract LINABLUE® is the only natural blue colorant that has been approved in North America, EMEA and APAC regions.

Our parent company, the DIC Corporation, has more than 40 years of expertise working with this natural blue colorant. We offer both a liquid and a powder form along with customized application support to meet your needs.

Tour Our Farm

In 1976, a group of U.S. visionary pioneers founded the Proteus Corporation to develop spirulina, a blue-green algae, as a world food resource. This team began cultivation in a hot desert area in Southeastern California and later changed the company’s name to Earthrise Nutritionals.

Since 2005, Earthrise Nutritionals is wholly owned by our parent company DIC. Discover the source of our natural blue colorant LINABLUE® by taking a virtual tour of our California Spirulina farm – the largest in the world.
