US FDA approves new, natural Everzure™ Galdieria expanding Givaudan’s portfolio of blue colours

Givaudan Sense Colour is pleased to announce FDA approval for Everzure™ Galdieria, a natural colour additive made from Galdieria sulphuraria. Developed in collaboration with French biotech company Fermentalg, this novel blue is fermented and extracted from microalgae using patented processes. The result is a phycocyanin-rich natural blue colour, similar to spirulina, with complete traceability and low pH stability that broadens the scope of application and use beyond where spirulina can be used.

”With increasing regulatory pressure and bans on synthetic colours, Sense Colour’s unique natural solutions are particularly relevant for today’s regulatory landscape. Until now, achieving vibrant blues in low pH applications, such as candies and soft drinks, using natural colours was a major obstacle for manufacturers. Everzure™ Galdieria offers a natural option with a vibrancy that mirrors Blue 1, allowing our customers to create enticing food experiences without compromising on naturalness,” says Nathalie Pauleau, Global Product Manager for Givaudan Sense Colour.

Leveraging Fermentalg’s deep expertise in blue biotechnology and precision fermentation, Everzure™ Galdieria is sustainably produced via the controlled fermentation of the microalgae Galdieria sulphuraria, followed by a gentle water extraction. 

Fermentalg’s proprietary fermentation process ensures consistent quality, efficient resource use, and scalable production—hallmarks of its leadership in algae-based innovation.

“This new blue colour is the result of more than five years of close collaboration with Fermentalg. It represents a significant milestone in our ongoing work in the biotech space. Natural ingredients developed with the help of biotechnology hold the promise of delivering better, cleaner and more enticing food experiences for consumers,” says Raja Chouket, Category Technical Lead for Sense Colour. “This approval will allow us to advance into production and commercialisation, making this long-awaited solution available to the market.” 

Approval by the US FDA marks the first authorisation for use in food and beverages, with additional petitions in process in Europe and the UK. Everzure™ Galdieria is currently available for sampling in the US with production scale-up beginning in H2 2025. Visit www.ddwcolor.com.
