Danish Start-up Reduced Raises €4M to Turn Food Waste Into Savoury Flavours

Copenhagen-based Reduced has raised €4M in Series A funding to scale its fermentation technology that converts food processing waste into natural savoury flavour ingredients.
Its "Waste to Taste" platform uses rice koji fermentation to produce complex flavour compounds, including umami and kokumi, in just three days, using 90% less energy than conventional methods.
With total funding now at €12M, the startup is targeting multinational food manufacturers and foodservice operators seeking cleaner, more sustainable alternatives to hydrolysed proteins and yeast extracts.
The global savoury flavour market is estimated to be worth $9 billion, yet the processes behind it remain largely opaque and energy-intensive. A Danish startup believes fermentation and food waste can do better: and investors are beginning to agree.
Reduced, founded in Copenhagen in 2016 by Emil Munck de Voss and William Anton Lauf Olsen, has closed a €4M ($4.7M) Series A round co-led by Delphinus Venture Capital, with participation from Novo Holdings, the European Circular Bioeconomy Fund (ECBF), and the Danish state fund EIFO. The raise brings its total funding to €12M ($14.2M) and will be used to scale production capacity, broaden its product portfolio, and deepen relationships with industrial partners globally.
Waste as a Raw Material
Reduced's technology, branded "Waste to Taste", centres on solid-state fermentation combined with controlled reaction processes to convert food industry sidestreams, byproducts from processing that would otherwise go to waste, into high-value flavour concentrates. The process uses rice koji, a mould (Aspergillus oryzae) long used in East Asian food traditions to break down starches and proteins, as its primary fermentation agent.
The results are flavour compounds that replicate the sensory depth typically associated with expensive or highly processed ingredients. These include umami (a savoury, protein-derived taste), kokumi (a less familiar sensation describing mouthfeel, thickness, and lingering flavour), and Maillard reaction notes: the roasted, browned character familiar from cooked meat or bread. Reduced's current product range spans mushroom, vegetable, shore crab, and chicken concentrates, all produced without additives.
Crucially, the process takes just three days, consumes roughly ten times less energy than conventional flavour production, and generates up to 83% fewer greenhouse gas emissions. Food waste itself is a significant climate problem: it is estimated to account for as much as a tenth of global greenhouse gas emissions and causes around $1 trillion in annual economic losses. Reduced claims to have diverted more than 150 tonnes of food waste from disposal to date.
Filling a Gap in Clean-Label Demand
The timing is not incidental. Across Europe, food manufacturers face growing pressure to remove artificial and heavily processed ingredients from their products: a shift broadly described as the "clean-label" movement. Yet the ingredients they currently rely on for savoury depth, such as hydrolysed vegetable protein and yeast extracts, are themselves produced through processes that sit uneasily alongside clean-label claims.
Reduced positions itself directly in that gap. Its fermentation-derived concentrates offer the complexity that synthetic or overly processed alternatives often lack, while remaining traceable and additive-free. The broader challenge of improving flavour in plant-based formulations is one the industry has grappled with for years, and fermentation-derived ingredients are increasingly seen as a credible path forward.
Reduced is not alone in this space. The trend of converting food processing sidestreams into protein- and flavour-rich ingredients via fungal fermentation is gathering pace across Europe, as startups and investors alike recognise both the environmental logic and the commercial opportunity.
From Lab to Industrial Supply
De Voss has described 2026 as a year focused squarely on industrialisation—translating a well-proven technology into a supply chain capable of serving multinational customers at scale. Over the past year, the company has already doubled its industrial partnerships and extended its product lineup across multiple applications.
Investors appear confident in the trajectory. Novo Holdings noted the strength of Reduced's enzyme- and fermentation-based platform, while ECBF pointed to its potential as a model for circular, bio-based food ingredient production. The next test, as with many food technology ventures, will be whether the economics of scale hold as cleanly as the science.
