Frequently Asked Questions

Why is a stable natural blue color so hard to find?

There are few blues available in nature, and those that are available are limited in their stability by their botanical source. Sensient’s R&D team is hard at work expanding the stability of natural blue solutions like Marine Blue™.

How can I naturally make drinks blue colored?

Sensient’s Marine Blue™ Capri is an acid- and water-stable spirulina-based natural color designed to be a bright blue in drinks and similar applications.

What is the difference between spirulina vs butterfly pea flower?

Spirulina is a bright, sky blue, similar to FD&C Blue 1, while butterfly pea flower extract offers a deeper denim blue to rich purple depending on the pH. Sensient’s Marine Blue™ portfolio expands the applicability and stability of spirulina.

What is the heat stability of phycocyanin in food?

Standard spirulina solutions are sensitive to heat, but Sensient’s Marine Blue™ portfolio includes stabilized spirulina solutions with improved heat stability.

What is the best heat stable natural green color for gummies?

The best heat-stable natural green color for gummies is a blend of a natural yellow color (like turmeric or beta carotene) and Sensient’s Marine Blue™ Azure, which was specifically developed as a bright blue for gummy-type applications with a heat step.
