Israeli startup Gavan wants to explore the plant kingdom to find new, sustainable and healthy ingredients, and a use for every part of a nutritionally dense substance. The first ingredient it worked with was the microalgae spirulina, and for a very distinct reason.

“We could see the separation and the extraction with our eyes because the proteins are blue,” Gavan co-founder and CEO Itai Cohen said.

The microalgae's standout blue pigment not only helped Gavan figure out how to fully separate the proteins in spirulina, but it also drove the company's first actual product launch: a stable natural blue coloring for both hot and cold drinks. Gavan is in touch with several manufacturers who are testing the coloring for potential use in products. Cohen said he hopes the company can begin commercial-scale production in the first quarter of 2023.
