Givaudan Sense Colour has recently gained FDA approval for Everzure™ Galdieria, a natural colour additive made from Galdieria sulphuraria, in food and beverages. 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 acid stability that broadens the scope of application and use beyond where spirulina can be used.
Nathalie Pauleau, Global Product Manager for Givaudan Sense Colour said, “With widening bans on synthetic colours, Sense Colour’s unique natural solutions are particularly relevant for today’s regulatory landscape. Until now, achieving vibrant blues in acidic applications 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.”
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.
Raja Chouket, Category Technical Lead for Sense Colour mentioned that the new blue colour is the result of more than 5 years of close collaboration with Fermentalg. This approval will allow Givaudan to advance into production and commercialisation, making this long-awaited solution available to the market.
Additional approvals are also sought in the EU and UK markets. Currently, Everzure™ Galdieria is only available for sampling in the US with production scale-up beginning in 2nd half 2025.
