Fermentation is an age-old technique that has been vital for food and beverages. It’s how we get bread, beer, cheese, and soy sauce. Recently, this process is transforming into a cutting-edge biotechnology method, capable of changing how we create and consume food.
In the past, fermentation focused mainly on mimicking dairy proteins like casein and whey. These developments were just the start. Today, startups and researchers are pushing boundaries, exploring alternatives for fats, flavors, and other ingredients.
Troels Prahl, CEO of Swan Neck Bio, believes the next breakthroughs will be in producing fats, flavors, and specialized ingredients like enzymes. “These are high-value products that are tricky to source naturally,” he says. “Fermentation can make them more reliable and affordable.” Claus Lattemann of Lesaffre Institute agrees, highlighting that fermentation can lead to multifunctional ingredients, improving nutrition and sustainability.
With global supply chains under strain—from cocoa to palm oil—fermentation could help fill gaps. For instance, it can provide substitutes for scarce ingredients like vanilla or citrus oils while offering essential nutrients. Prahl points out that it’s also eco-friendly and could help revamp our food systems by partnering with agriculture.
Looking ahead, with the world’s population nearing 10 billion by 2050, fermentation presents an opportunity for more sustainable protein production. A study by the UK Food Standards Agency (FSA) suggests that next-generation fermentation innovations could contribute nearly £10 billion to the economy by then. With adequate investment in research and development, this value could soar to £5.9 billion, similar to today’s UK beer industry.
Despite its promise, consumer acceptance remains a hurdle. Prahl notes that people often find biomanufactured ingredients less familiar. Brands need to communicate clearly about how these foods can be safe and tasty. As he points out: “Consumers often connect words like ‘fermentation’ with something too technical.”
Authentic flavor is another challenge in the fermentation realm. Advanced techniques now allow for the creation of flavor compounds that genuinely mimic those found in natural sources like meat or vanilla. Already, brewers are experimenting with hop-free beers, using engineered yeast to simulate aromatic compounds.
However, the journey isn’t without its bumps. Scaling up fermentation is expensive and resource-heavy, and regulatory processes can be complicated. Strategic partnerships are essential for overcoming these barriers. Swan Neck Bio, for example, is teaming up with Tetra Pak to speed up pilot testing, which could help make fermentation systems more efficient.
In summary, fermentation is shifting from a focus on dairy and meat to a wide array of ingredients that could revolutionize our food systems. The future looks promising, but success hinges on collaboration across sectors and transparent communication with consumers. If managed well, fermentation could redefine how we think about production, sustainability, and health in our food.
