The Future of Fermentation
How an ancient process could help build a more sustainable food system
by Steven DuPuis
For thousands of years, fermentation has helped us preserve food, enhance nutrition, improve digestibility, and create deeper, more complex flavors. Bread, cheese, beer, yogurt, miso, tempeh and countless other foods exist because humans learned how to work with microorganisms.
What excites me is how we can use fermentation to improve the foods we eat; we may only be beginning to understand its greater potential to create entirely new foods and ingredients, make better use of what we grow, reduce waste, and help build a more sustainable, resilient food system.
Over the past decade, I’ve had the opportunity to explore this world firsthand through the development of the Planit POD, working alongside food scientists, fermentation experts, and chefs to better understand not only how fermentation works, but how it can create entirely new ingredients and flavors. What we’ve learned has led me to a bigger idea: fermentation could become a key tool for rethinking how we produce food.
From Preserving Food to Reinventing It
Traditional fermentation, biomass fermentation and precision fermentation are enabling us to transform grains, legumes, fungi and agricultural by-products into new proteins, ingredients, flavors and textures. Researchers are even demonstrating how fungal fermentation can turn food-production by-products into nutritious new foods.
That creates an intriguing possibility: instead of continually growing more to produce more, what if we could get more value from what we already grow?
A Different Sustainability Equation
Our food system is deeply connected to climate change, from land and water use to agriculture, processing, transportation, and waste.
Fermentation cannot solve all of those challenges. But it can become part of a more circular food system: creating new sources of protein, extending the usefulness of crops, transforming underutilized ingredients, and potentially reducing waste.
And unlike many sustainability solutions, fermentation offers something consumers actually want: better food, with deeper flavor, natural umami, new textures, better ingredients, and entirely new culinary experiences.
The Opportunity Ahead
I believe the real promise of fermentation sits at the intersection of food, science, sustainability, and creativity.
For food companies, that makes fermentation more than a technology trend, it is an innovation platform that opens the door to entirely new products, ingredients, flavors and ways of producing food. The question is no longer simply, What can we ferment? but rather, What could fermentation allow us to create that wasn’t possible before? That is where I believe the future gets interesting.….
