Food-tech venture React Foods, a spin-out utilising technology developed by researchers at Aarhus University, the Novo Nordisk Foundation CO₂ Research Center (CORC), and international partners, has entered the alternative protein landscape.

Backed by early-stage funding from the BioInnovation Institute (BII), the start-up is deploying gas fermentation systems to turn CO₂, hydrogen, and microorganisms into high-protein yeast ingredients suitable for human consumption.

Unlike first-generation plant proteins that require extensive land and water or biomass fermentation requiring sugar feedstocks, React Foods captures emissions directly and converts them into nutritional building blocks using renewable energy.

Technology overview

• Primary inputs: captured carbon dioxide CO₂, green hydrogen, and targeted microorganisms.
• Processing technology: gas fermentation and biological synthesis.

• Core output: high-purity, food-grade yeast protein ingredients.

• Key environmental value: zero-agricultural-land reliance, minimal water footprint, and direct carbon sequestration.

• Commercial positioning: B2B functional ingredient partner for food manufacturers facing agricultural supply chain volatility.

Upstream carbon capture meets sustainable sourcing

React Foods’ development marks a shift in how the food and drink sector views sustainable sourcing. For years, ingredient suppliers focused on crop optimization or upcycling agricultural side streams. Gas fermentation goes a step further by removing land use from the equation entirely.

By capturing atmospheric or industrial carbon and converting it into complete yeast protein, companies like React Foods address two of the largest headwinds currently facing major food manufacturers: climate-driven agricultural price volatility and scope 3 emissions targets. The ultimate test for this technology will be achieving the scale and cost parity necessary to integrate seamlessly into high-volume reformulations across plant-based, bakery, and functional food categories.

Sector impact

For food manufacturers, ingredient buyers, and product developers, React Foods demonstrates that carbon-negative raw materials are moving closer to commercial reality. As regulatory and consumer pressure to lower scope 3 emissions intensifies, mastering non-agricultural protein inputs will provide a vital buffer against land constraints, severe weather disruptions, and volatile commodity pricing.
