US biotech company Debut and Danish natural color supplier Oterra have announced a multi-million-dollar collaboration to develop a fermentation-derived alternative to Red 40, one of the most commonly used synthetic food colorings in the United States.
The partnership will apply Debut’s precision fermentation platform to produce natural color solutions covering orange, red, and violet shades, with Oterra contributing its formulation expertise to prepare the ingredient for commercial food and beverage applications. The two companies plan to work with food and beverage manufacturers ahead of launch while pursuing an FDA approval filing, with a commercial product targeted within approximately three years.
Regulatory pressure is accelerating the shift
The FDA and the Department of Health and Human Services have called on food manufacturers to phase out certain FD&C certified synthetic colorings by the end of 2026, putting pressure on producers to identify credible alternatives. Red 40, a petroleum-derived dye, has faced particular scrutiny.
Debut CEO Joshua Britton said: “Biotech offers clear advantages that align with evolving market demand. Its adoption in the food and beverage industry is particularly compelling, providing a high-performance alternative to FD&C colors and Red 40, which faces increased regulatory scrutiny.”
The fermentation-based production process is also expected to reduce land and water use compared with plant-derived red colorants, which are subject to agricultural variability. The resulting ingredient will be compatible with vegan, kosher, and halal certifications.
Oterra’s existing foothold in natural reds
Oterra, which traces its roots to 1876, already supplies natural red alternatives to food manufacturers globally, including alternatives to Red 40, and positions the Debut collaboration as a way to expand and strengthen that portfolio through biotechnology.
Luc Ganivet, Head of Innovation at Oterra, said: “Our collaboration with Debut brings exciting new technology options to significantly strengthen our natural portfolio with optimized technical performance. It also offers secure supply, independent of weather and harvest without compromising on natural credentials.”
The Debut-Oterra collaboration, however, is specifically targeting the performance and stability requirements that have historically made synthetic dyes difficult to replace at scale, particularly in applications requiring consistent hue across varying pH levels and processing conditions.
