Oterra and Debut partner to develop alternative to Red 40

Natural colour specialist Oterra and artificial intelligence-powered biotechnology pioneer Debut have announced a multi-million-dollar partnership to develop and scale a fermentation-derived alternative to Red 40, one of the most widely used synthetic colour additives in US food and beverage products.

The joint effort aims to address a critical bottleneck for food manufacturers. As consumer advocacy and regulatory bodies push for the removal of petroleum-derived dyes, brands have struggled to find natural red replacements that match the intense stability, vibrant shade, and cost-effectiveness of synthetic colours.

By combining Debut’s advanced biomanufacturing technology with Oterra’s established blending and formulation expertise, the alliance plans to overcome these limitations. The collaboration is designed to produce a highly stable, full range of natural shades spanning orange, red, and violet.

The timing of the partnership is highly strategic. The US Food and Drug Administration (FDA) and Department of Health and Human Services (HHS) have actively encouraged food manufacturers to phase out certain FD&C certified food colourings by the end of 2026. This federal guidance has greatly accelerated the industry-wide demand for high-performing natural alternatives.

By utilising biotechnology, the two companies aim to provide a high-performance, compliant solution before regulatory deadlines disrupt retail availability. Debut and Oterra are already collaborating with leading food and beverage companies ahead of commercialisation. They are currently working toward an FDA approval filing, with the goal of bringing a commercially scaled product to market in approximately three years.

While botanical sources like beetroot or sweet potatoes already provide natural red hues, they are highly vulnerable to supply chain disruptions, crop failures, and seasonal price fluctuations.

Transitioning the colour sourcing to precision fermentation — a process that uses engineered microorganisms to produce identical target pigments in controlled vessels — insulates food brands from these external risks. The advanced precision fermentation techniques also offer significant environmental advantages, contributing to reduced land and water use compared with traditionally cultivated agricultural sources.

Luc Ganivet, head of innovation for Oterra, highlighted how the technology de-risks raw material procurement for food brands: “Our collaboration with Debut brings exciting new technology options to significantly strengthen our natural portfolio with optimised technical performance. It also offers secure supply, independent of weather and harvest without compromising on natural credentials. Oterra has a 150-year heritage of innovating colours from natural sources including several Red 40 alternatives.”

To ensure seamless integration across a wide range of global product portfolios, the biotech red colour is being developed to meet diverse dietary and religious standards. The Red 40 alternative will work in a broad range of applications and will also be compatible with vegan, kosher, and halal certifications.

Joshua Britton, PhD, founder and CEO of Debut, emphasised the commercial viability of biotechnology in modern food science: “We’re excited to fast-track the commercialisation of natural red alternatives from precision fermentation with Oterra. 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 colours and Red 40, which faces increased regulatory scrutiny.”
