The latest food and beverage industry news and trend analysis

Givaudan Sense Colour has announced that the European Food Safety Authority (EFSA) has issued a positive scientific opinion regarding the safety of blue galdieria extract. The assessment marks a critical step toward the final authorisation of Everzure Galdieria as a food colour additive in the European Union. The extract is positioned as a high-performance natural alternative to synthetic Brilliant Blue FCF (E133).

The file now moves to the European Commission, which will determine final authorisation for use across the EU member states.

Technical Advantages and Acid Stability

Everzure Galdieria is derived from Galdieria sulphuraria, a microalgae known for its resilience. A primary driver for this innovation is its acid stability, which allows for applications in categories where existing natural blues, such as spirulina, typically fail.

Once fully authorised, the extract will enable manufacturers to achieve vibrant blue, green, and purple shades in acidic environments, including:

• Beverages

• Confections

• Sports and Energy Drinks

The shade provided by the extract closely matches the profile of Brilliant Blue, allowing brands to maintain visual appeal while meeting consumer demand for natural ingredients.

Partnership and Biotechnical Production

The product was developed through a strategic collaboration with Fermentalg, a French biotech company specialising in blue biotechnology. The production process utilises precision fermentation followed by a gentle water extraction.

This proprietary method ensures a scalable and consistent supply chain, which is often a challenge for natural pigments. Barry Foley, Regulatory Director for Givaudan Sense Colour, noted that the milestone follows rigorous testing of the extract in various food and beverage applications to support the intensive EFSA assessment.

Global Market Context

While awaiting final European Commission approval, Everzure Galdieria is already approved for use and available for sampling in the United States. This existing regulatory status in North America provides a baseline for global manufacturers looking to synchronise their international product portfolios.

Nathalie Pauleau, Global Product Manager for Givaudan Sense Colour, stated that the close colour match to synthetic options will allow customers to create novel food experiences without compromising on natural labelling. The success of this regulatory pathway reflects Givaudan’s ongoing investment in algae-based innovation and sustainable ingredient sourcing.
