Leaft Foods Partners with Lacto Japan to Introduce Revolutionary Leaf Rubisco Protein to Japanese Market

Strategic partnership leverages Lacto's market expertise to bring next-generation protein to Japan's innovation-driven food manufacturers 

ROLLESTON, New Zealand and TOKYO, Sept. 9, 2025 /PRNewswire/ -- Leaft Foods, a company that harnesses the planet's most plentiful protein extracted directly from green leaves to make industry-defining products, today announced a strategic partnership with Lacto Japan Co., Ltd., a leading distributor and producer of specialty food ingredients. The collaboration will accelerate the commercialization of Leaft's groundbreaking Rubisco Protein Isolate within Japan's sophisticated food manufacturing sector.   Leaft's Rubisco Protein Isolate represents a paradigm shift in the protein industry. What makes Rubisco so unique is that it combines nutritional and functional properties that outperform animal incumbents like whey protein. Leaf Rubisco also delivers an amino acid profile superior to whey protein, setting a new gold standard for protein nutrition.

Beyond its exceptional nutritional profile, Leaf Rubisco offers outstanding food functionality, capable of replacing eggs, emulsifiers, and gelling agents while enabling food manufacturers to substitute artificial ingredients with a clean-label protein that humans have consumed throughout history. This performance is delivered through a commercialized production system that is backed by forward contracts and satisfies both quality and sustainability imperatives.

Lacto Japan brings decades of experience connecting ingredient companies from New Zealand and Australia with major players in the Japanese food industry. The company's deep integration within the sector and proven track record with protein ingredients made them the ideal partner for Leaft's debut in Japan, renowned as a global hub for food innovation. Broadly, the partnership aligns with Leaft's global commercial strategy, which focuses on innovation-driven markets where demand for next-generation proteins is rapidly accelerating.   "It has been tremendously exciting to work with Lacto, a capable and innovative partner, as we've sought to enter the sophisticated Japanese market," said John Penno, co-founder of Leaft Foods. "Lacto's role as our trusted local collaborator has been invaluable in providing essential market and supply chain intelligence and relationship management that can enable successful market penetration."  "It is not every day that you discover such an exciting new protein," said Takeshi Shimizu General Manager Oceania at Lacto Japan. "What impressed us most was not only the protein system itself, but the fact that we have been able to work with it in a range of promising applications from the start. The quality, texture and flavor of the foods produced meet the exceptionally high standards that Japanese consumers expect."  The companies are already engaged with several of Japan's most important food manufacturers across plant-based foods, bakery products, and sports nutrition categories, demonstrating early market validation for the innovative protein. Their goal is to build a business worth tens of millions of dollars (USD) over the next five years.  About Leaft Foods
