SME Business Review reached out to Dr. James Petrie, CEO of Nourish Ingredients, for an interview to gain deeper insights into the company's innovative approach to redefining plant-based food experiences and its vision for the future of sustainable food production. Here’s what Dr. Petrie had to say.

Interview Excerpts

Could you tell us about the inspiration behind founding Nourish Ingredients?

The inspiration stemmed from identifying a significant gap in the plant-based food sector. While many were focused on replicating protein, the role of fats was largely overlooked. Fats are critical to how food tastes and feels, yet plant-based options rarely get this right. My co-founders and I wanted to address that challenge using precision fermentation. It wasn’t just about creating an alternative—it was about crafting something that genuinely replicates the sensory experience people expect from traditional animal products.

How does precision fermentation work, and why is it a game-changer for food innovation?

Precision fermentation is a highly specialized process that uses microorganisms, such as yeast or bacteria, to produce specific ingredients—in our case, fats. We program these microorganisms with the genetic instructions they need to create complex molecules that mimic animal fats. This process allows us to achieve a level of accuracy and functionality that’s unmatched by plant-based substitutes alone. What makes it transformative is the potential to scale and integrate this technology into global food production, offering a sustainable and versatile solution to a critical issue.

Why did you choose to focus specifically on fats?

Fats are the unsung heroes of food. They contribute to flavor, texture, and mouthfeel in ways that are fundamental to the eating experience. Without the right fats, plant-based foods often fall short of replicating the satisfaction of their animal-based counterparts. We wanted to address that gap. By focusing on fats, we’ve been able to create a product that elevates plant-based food quality and gives consumers a real alternative that doesn’t feel like a compromise.

How do you work with food manufacturers to integrate your technology into their products?

Collaboration is at the core of what we do. We partner with food manufacturers to understand their specific needs and tailor our fats to fit their product requirements. Whether it’s a plant-based burger, a dairy-free ice cream, or a pastry, we work closely to ensure that our fats deliver the right performance and sensory experience. It’s about enabling our partners to create products that meet consumer expectations without sacrificing sustainability.

What challenges have you faced in scaling precision fermentation, and how are you addressing them?

Scaling precision fermentation is no small task. The infrastructure required to produce these fats at a commercial scale is both complex and capital-intensive. It’s also a process that demands significant research and development to optimize efficiency and output. To address these challenges, we’ve invested heavily in building partnerships with industry experts and securing funding to expand our operations. Our focus is on creating scalable solutions that can meet the growing demand for sustainable food options.

How do you see your work contributing to a more sustainable food system?

Our work directly addresses some of the most pressing environmental challenges in food production. Traditional livestock farming is incredibly resource-intensive, consuming large amounts of water, land, and feed while generating significant greenhouse gas emissions. By creating fats through precision fermentation, we’re offering a solution that reduces the need for animal agriculture, conserves resources, and lowers emissions. It’s about building a food system that can support a growing global population without depleting the planet.

What role does consumer perception play in the adoption of your products?

Consumer perception is everything. People won’t adopt sustainable alternatives if they feel like they’re compromising on taste or quality. That’s why we’re so focused on the sensory aspects of our fats. By creating products that replicate the experience of traditional animal fats, we’re showing consumers that sustainability and indulgence can go hand in hand. Changing the narrative around plant-based foods is essential to driving widespread adoption.

Could you share more about the potential impact of your work on food accessibility?

Accessibility is a key consideration for us. As we continue to scale our technology, we’re focused on reducing production costs to make high-quality plant-based foods affordable for a broader audience. Sustainability shouldn’t be a luxury; it should be an everyday choice for everyone. By lowering the barriers to entry, we’re working to democratize access to better food options.

How do you balance innovation with practicality when developing your products?

Innovation is at the heart of what we do, but it has to be grounded in practicality. Our fats aren’t just designed to perform in a lab; they’re created to work seamlessly in real-world applications. Whether it’s cooking, baking, or product formulation, we test our fats extensively to ensure they meet the practical needs of food manufacturers and consumers. That balance is what makes our products both innovative and usable.

What has been the most rewarding part of leading Nourish Ingredients?

The most rewarding part is seeing the tangible impact of our work. Whether it’s collaborating with a manufacturer to launch a new product or hearing from consumers who are genuinely excited about the quality of plant-based foods, those moments reaffirm why we do what we do. It’s incredibly fulfilling to know that we’re contributing to a more sustainable and equitable future.

Where do you see Nourish Ingredients in the next five years?

Over the next five years, we want to expand our reach and deepen our collaborations with manufacturers across the globe. Scaling our operations to meet the growing demand for sustainable fats is a top priority. We’re also looking to explore new applications for our technology, broadening the scope of what precision fermentation can achieve in food production. Ultimately, our goal is to make sustainable fats an integral part of the food system, ensuring that everyone has access to better, more ethical choices.
