GRA Nutra AG introduces AuraBC™, a natural, clean-label, beta-carotene food colour derived via non-GMO fermentation technology. AuraBC™ provides warm yellow-to-orange tones to a broad spectrum of food and beverage applications. The company is set to operate its vertically integrated production facility with minimal ecologic footprint. GRA Nutra will showcase its natural beta-carotene shades in a selection of beverages and gummies at IFT FIRST, Chicago, July 13-15.
GRA Nutra’s proprietary fermentation and formulation technologies bring natural beta-carotene derived food colorants to food and beverage manufacturers, positioned for broad market adoption.
Food-friendly colours
“The food colour market is rapidly shifting away from FD&C petroleum-based and other synthetic dyes toward natural, clean‑label pigments,” explains Lynda Doyle, CEO of GRA Nutra Corp. “This is driven by consumer distrust of artificial colours, retailer and regulatory pressure, and aggressive reformulation by major brands. Our fermentation-based colors break through the cost barrier of delivering natural alternatives that are environmentally sound.”
In the U.S., the transition from synthetic dyes is being accelerated by FDA’s revocation of Red No. 3, as well as a broader initiative to phase out petroleum‑based certified colours in the coming years. This comes alongside state-level restrictions, especially as applied to school food service. In Europe, the ban against titanium dioxide and certain FD&C dyes reinforces a global pivot toward reducing synthetic additives.
Non-GMO fermentation and formulation technology
“Our proprietary fermentation technology is the key to optimising beta-carotene yields from naturally occurring strains,” explains Guido Schaer, co-founder and Chairman of GRA Nutra AG. “The process is vertically integrated, combining ingredient production, extraction, purification, and formulation within a single facility. This integrated model reduces transport, minimizes energy use, and improves overall efficiency and sustainability.
AuraBC™ is available in versatile formats such as spray-dried powders, beadlets, granulations, oil suspensions and emulsions. The beadlet formulation provides consistent performance and exceptional stability across diverse applications and conditions, while delivering excellent solubility, dispersibility, bioavailability, and organoleptic properties. These formats help to maintain color vibrancy and to reduce processing losses. AuraBC™ natural beta-carotene can be standardized to concentrations ranging from 1% to 30%.
Sustainability by definition
GRA Nutra’s manufacturing process relies heavily on renewable energy, either generated on site using solar panels or through certified renewable PPAs. “Our commitment to sustainability extends beyond energy use to the very materials we work with,” asserts Doyle. “Unlike petrochemical-based production, our colorant sources are renewable, fermentation-based and algae-derived active ingredients. We prioritize short, efficient supply chains and partner only with suppliers who share our vision of achieving a zero-carbon footprint.”
