Dutch Startup Unveils Fermotein: A Fungal Protein 26x More Efficient Than Beef
A Dutch food-tech startup, The Protein Brewery, is preparing to launch a new high-protein ingredient called Fermotein. The product, made from fungal fermentation, promises far greater efficiency than traditional protein sources. Meanwhile, life expectancy in Western Europe has risen sharply since 1950—but many of those extra years may be spent in poor health.
The Protein Brewery has developed Fermotein, a mycoprotein ingredient derived from Rhizomucor pusillus, a heat- and acid-resistant fungal strain. The company claims it yields 26 times more protein per kilogram than beef, while using just 1% of the land, 5% of the water, and emitting 3% of the greenhouse gases. Compared to soy and peas, it produces five and four times more protein, respectively.
The ingredient has a perfect protein quality score (PDCAAS of 1), supports muscle maintenance, and contains around 30% dietary fibre with potential prebiotic benefits. One of its key components is spermidine, a compound linked to cellular repair processes like autophagy, which may help reduce oxidative stress. However, there is no scientific evidence that Fermotein itself extends lifespan.
Regulatory progress is underway, with approvals already secured in Singapore and the US. The European Food Safety Authority has given a positive opinion, and EU clearance is expected between Q2 and Q3 of 2026. To accelerate production, the company raised €30 million in Series B funding last year. Scaling plans aim for hundreds of tonnes of Fermotein by 2026, targeting wider adoption in plant-based and alternative protein markets.
Separate data shows that while life expectancy in Western Europe has increased by 17 years since 1950, over half of the additional lifespan for those born in 2024 may involve health complications. The contrast highlights ongoing challenges in healthcare, even as food innovation advances.
The Protein Brewery's Fermotein is set to enter the market with strong efficiency claims and regulatory backing. Production expansion is planned for 2026, though its long-term health impacts remain unproven. In parallel, rising life expectancy in Western Europe continues to outpace improvements in late-life health.
