John Penno and his spouse Maury Leyland Penno realized about six years in the past that it was time to dedicate their lives to one thing that is higher for the atmosphere.
It was a significant life determination for the pair, who have been each executives in New Zealand’s dairy trade. John Penno had co-founded dairy dietary firm Synlait, and Maury Leyland Penno was an government at Fonterra. They needed to take their data and passions — in addition to their agriculture-focused viewpoint from their residence nation of New Zealand — into the choice proteins area. However they weren’t certain simply what their enterprise can be. In any case, there have been many gamers in plant-based protein, and it appeared unlikely that they might be capable to break into the crowded soy or pea elements area.
Then Maury Leland Penno took her husband to a hackathon. They listened to a researcher discuss a challenge from the Eighties that handled leafy greens. And that bought them each considering.
“Leafy crops are very, very productive, these perennial vegetation,” John Penno stated. “You mow them off they usually simply hold coming again with the sunshine. And the protein manufacturing in that leafy cropping system is gigantic. It is a very, very environment friendly means of harvesting daylight, water and vitamins and producing protein and carbohydrates and all the opposite stuff you need to produce.”
The substance that makes leafy greens such a life power is a protein referred to as rubisco. It’s required for photosynthesis, and researchers have stated it is the most abundant protein on this planet. The Pennos began Leaft Meals, an organization that extracts rubisco out of leaves and turns it right into a inexperienced protein gel, which it could course of right into a tasteless and odorless protein powder. Rubisco, which has an identical amino acid profile to beef, is a powerhouse ingredient that may be added to any meals product, and that may supercharge the dietary worth of any plant-based dish, in accordance with the corporate.
Final month, Leaft closed a $15 million Series A investment round. The spherical, led by Khosla Ventures, noticed participation from NBA star Steven Adams, New Zealand indigenous investor Ngāi Tahu and the Local weather Change Influence Fund of New Zealand sovereign well being supplier ACC. The funds might be used to construct Leaft’s R&D, assist the corporate develop, and start to ascertain a world worth chain beginning within the U.S.
From a kitchen experiment to sports activities vitamin
Rubisco is already in each plant. When shoppers eat a salad, they’re getting a dose of its high-quality protein. Herbivores, together with massive ones that want a variety of vitamins like gorillas, get a variety of their protein that means.
People do eat some leafy greens, Maury Leland Penno stated. However we do not eat sufficient to get the focus of rubisco that might absolutely meet dietary wants — and the human physique is not precisely constructed to digest the massive quantity of leafy greens to get that a lot rubisco.
Leaft’s proprietary course of takes the rubisco and concentrates it so it may be within the quantities that might meet people’ protein necessities.
John Penno stated that rubisco is exclusive in a number of methods. It is not like a protein that comes from a legume, together with pea or soy, or from a grain, like wheat.
“It is energetic. It is far more like an animal protein in that,” he stated. “…It has fantastic properties. In its pure kind, it is tasteless, odorless. And whereas that sounds boring, for a protein as an ingredient or a drink, it is marvelous constructing block for meals. It is bought an incredible amino acid profile as a result of, once more, it is a functioning dwell protein. It is bought work to do and it is working inside.”

Earlier than the corporate was formally began, Maury Leland Penno did an intensive assessment of scientific writings about rubisco. She had been capable of get a inexperienced rubisco gel out of kale leaves of their kitchen. So the following step, John Penno stated, was discovering individuals who had the meals science data and talent to enhance the corporate’s product.
At the moment, Leaft nonetheless performs that first step: eradicating the inexperienced juice that incorporates rubisco from the vegetation it harvests. Then, much like dairy milk, Leaft takes that juice to a processing plant, Maury Leland Penno stated. A number of the processes to extract the rubisco and switch it into what appears to be like like a white powder are literally much like these utilized in dairy vegetation worldwide, she stated.
Whereas John Penno stated the corporate’s final objective is altering the world, Leaft is beginning out by making rubisco protein isolate and focus merchandise. He stated these are much like the whey and soy proteins which can be well-liked within the sports activities vitamin market. The rubisco protein that Leaft is making now appears to be like and behaves very equally, besides it is plant-based, eco-friendly, allergy-friendly and simply digestible, in accordance with the corporate. It additionally goes by a restricted quantity of processing and is by itself a really highly effective protein, Leaft says.
John Penno stated it is sensible for Leaft to start out with a direct-to-consumer product on this section to get the corporate on the market. He is additionally planning for this launch to happen in america, which has a big sports activities vitamin market. This sort of launch may also give Leaft the chance to do shopper analysis, discovering out what individuals consider the product and the way they need it for use. Leaft is in search of a U.S. staff to direct this, and Maury Leland Penno stated they’re focusing on a 2023 U.S. launch.
An ingredient for all the things — together with sustainability
Whereas rubisco protein powder is Leaft’s first deliberate launch, it is just the start. The Pennos stated they assume their rubisco will finally turn out to be used as an ingredient in all kinds of merchandise.
“It is an uncommon product as a result of it is fairly well-known,” John Penno stated. “So while you speak to the large meals producers of the world, they know concerning the protein. They know its potential, its performance, its amino acid profile. It is a very high-potential protein, and it has been checked out and researched. They simply wanted to discover ways to commercialize it.”
First, he stated, Leaft must get to the amount and scale to fill the potential demand, in addition to work out what rubisco protein can do. The corporate has a check kitchen that has been exploring the probabilities. Maury Leland Penno stated they’ve been capable of make a meringue-like cake from their rubisco protein, which might gel like egg whites.
Whereas there are different yet-undiscovered makes use of of Leaft’s rubisco, it has one attribute the Pennos are sure of: sustainability. As a result of rubisco is in each leafy inexperienced plant, there may be all kinds of potential sources that may be planted to reap it. Maury Leland Penno stated they’re targeted on planting nitrogen-fixing crops — which assist naturally fertilize soil — as a supply.
“What we’re coping with is the protein that is within the dwelling cell. And it is a dwell protein. It is energetic. It is far more like an animal protein in that. …It has fantastic properties.

Proper now, she stated, they’ve been working essentially the most with alfalfa, however that’s prone to change as they study extra. There doesn’t appear to be a lot of a distinction between the rubisco product that comes from various kinds of vegetation, John Penno stated. It is extra of a matter of what vegetation develop the perfect and quickest to create leaves wealthy within the protein, in addition to the opposite merchandise that might be created from these vegetation. After the rubisco is eliminated, the leftover plant fiber may make a nutritious animal feed, stated Maury Leland Penno. However there may additionally be different helpful parts in these fibers, like sugars or different elements to extract.
The Pennos are excited concerning the potential of rubisco, however they stated Leaft’s present work is just the start. For millennia, John Penno stated, plant agriculture has been about the identical issues: rising legumes, cereal crops and grains and utilizing only a portion of what’s harvested for meals. Leaft appears to be like at these vegetation in an entirely completely different means.
“In 30 years’ time, I’ve no query that the manufacturing of leafy crops and what comes from it is going to end in a complete lot of various meals and meals manufacturing programs,” he stated. “As we find out about it and unlock it, it is simply such an environment friendly means of harvesting daylight, vitamins and water. That is going to unlock, we expect, that step change that we’d like from our agricultural programs.”
