The molecular farming technology powering
high-performance products
We produce healthy and functionally identical animal-free proteins at scale, using duckweed, one of nature’s fastest-growing plants. Starting with Casein and Rubisco, we enable food producers to unlock the next generation of nutrition and wellness.
Our Proteins
The Final Frontier Protein Problem
Plant-based cheese is a 4.6 billion dollar category globally, even though it still does not melt or stretch. That is because casein, the protein responsible for the stretch, melt, and structure, hasn’t existed outside of cow’s milk until now.
What We Deliver
Aspyre produces scalable, affordable and animal-free casein. The same proteins found in milk. It unlocks and enhances:
- Texture, melt and stretch in cheeses (traditional, processed & vegan)
- Slow digestibility and sustained release in sports nutrition
- Water binding capacity in protein bars
Functional Profile
All nine essential amino acids and high in BCAAs
Micellar structure for functionality and stability
High digestibility (PDCAAS of approximately 1.0)
Why It Matters
Global demand for plant-based cheese is growing, but stretch, melt, texture and performance still blocks adoption. Casein is the primary bottleneck, and we're unlocking it.
We built this platform because casein is the holy grail of alternative proteins, and no one else could produce it at scale and price parity.”
The Most Underutilised Protein With Unmatched Potential
Rubisco is the most abundant protein on Earth, present in every green leaf around you. Despite its exceptional nutritional profile and clean taste, it has remained inaccessible due to extraction challenges at scale. Until now.
What We Deliver
Aspyre’s duckweed production, combined with our cost-efficient extraction process, makes Rubisco commercially viable. We extract high-purity Rubisco from duckweed, unlocking a new class of clean-label, allergen-friendly proteins.
It unlocks and enhances:
- Gelling in plant-based meat alternatives
- Protein solubility in smoothies and functional beverages
- Emulsification in sauces, dressings, and savoury applications
Functional Profile
Clean, neutral taste and colourless appearance
Low allergenicity and high digestibility
All essential amino acids (high lysine and leucine)
Why It Matters
Rubisco offers a path beyond soy, pea, egg white and whey proteins. It delivers full-spectrum nutrition without the off-notes, allergens or sustainability concerns of conventional proteins.
As a molecular farming graduate, I used to curse Rubisco as worthless contamination. Now I see it as one of the most valuable proteins on Earth.”
Our Advantage
We scale functional proteins faster, cleaner, and more cost-effectively from a single platform.
Animal-Free Product Layer
Identical casein, produced in plants, with full dairy functionality. We unlock the holy grail of alt proteins, enabling next generation cheese and food production.
Price Unlock Layer
Rubisco is a valuable ingredient that unlocks price parity. We maximise the value of duckweed and unlock a versatile ingredient for food producers.
Productivity Layer
Duckweed doubles in biomass every 48 hours, with protein levels equal to soy. This powerful biofactory enables year-round, consistent and high value protein production.
Control Layer
Low-cost and modular ponds in a controlled environment. Our approach reduces risks and enables consistent quality and yields.
Sustainability Layer
Minimal nutrient input, non-arable land, ultra-low water use. Our system is designed to enable carbon-negative production.
"Casein proves the power of duckweed as a biofactory and Rubisco unlocks new opportunities in functional food. But this is just the starting point. Ultimately the combination of duckweed and molecular farming is what enables us to scale, unlock new categories, and maximise the value of every gram we grow"
How It Works
Aspyre unlocks scalable production of high-performance proteins in five core steps:
Select the Target Protein
We focus on proteins with the highest functional and commercial impact.
Re-Engineer Duckweed to Produce
We engineer strains of duckweed to produce target proteins with high purity and stability.
Grow and Harvest
Duckweed is grown in closed-loop, modular ponds and harvested every 24 to 48 hours.
Extract and Purify
We isolate and refine proteins for application-specific performance: melt, stretch, solubility, foaming, and more.
Partner and Scale
We work with brands and producers to supply ingredients, co-develop new products, or launch JVs for global scale.
Built for More
Our processes are built to expand. While Casein and Rubisco are our primary focus today, the technology enables future production of:
Bioavailable & bioactive proteins for nutraceutical applications
Bioactive (skin-active) proteins for cosmetics and skin health
Therapeutic proteins for immune and metabolic support
