Rubisco Unleashed: The Leaf-Based Protein That Could Change Everything

In this episode of FoodTech Junkies, host Sharon Cittone sits down with Ross Milne, CEO of Leaft Foods, to explore one of the most under-reported scientific breakthroughs in modern food innovation: the successful commercial extraction of Rubisco, the most abundant and until now, most elusive protein on Earth.Ross shares his journey from designing some of the world’s largest food factories to pioneering a new protein category derived from green leaves, particularly alfalfa. Together, they unpack the science behind Rubisco, how Leaft cracked a century-old challenge, and why leaf-based protein could redefine sustainable nutrition, regenerative agriculture, and climate-aligned food production.The conversation goes deep into the environmental advantages, the integration of farmers into this emerging value chain, and the realities of bringing a novel food technology to market, from partnerships in Japan and pet nutrition to early consumer products. Ross also offers a rare look at where Rubisco fits into the future of food and how “rewriting photosynthesis” might become one of the century’s most powerful food-system tools.A must-listen for anyone interested in food innovation, climate solutions, and the next frontier of protein.Special Offer:Listeners get 40% off their first order at Leaft Foods.
