Leaft Foods and Verley showcased alternative protein technologies designed to address growing constraints in the global whey supply chain, introducing ingredients that aim to match whey’s nutritional and functional performance. Leaft Foods developed a process for extracting Rubisco protein from alfalfa leaves while preserving its structure and functionality, while Verley uses precision fermentation to produce beta-lactoglobulin, the primary protein found in whey.
Leaft Foods highlighted Rubisco’s complete essential amino acid profile, rapid digestion and ability to foam, gel and emulsify without the off-notes commonly associated with plant proteins. Verley emphasized the ability to tailor its milk-identical whey protein for specific performance attributes such as solubility and thermal stability. The article also highlighted Alpine Bio’s fractionated soy protein isolate as another emerging whey alternative.
For food manufacturers, these proteins offer supply diversification, functional flexibility and lower environmental impacts, supporting continued growth in high-protein food and beverage categories.

Key Themes Behind This Trend
- Whey-free Protein Formulation
- New plant-derived and fermentation-made proteins are expanding the high-protein product landscape by delivering whey-like nutrition, texture, and processing performance without relying on constrained dairy supply chains.
- Functional Plant Protein Extraction
- Rubisco extraction from leafy crops signals a new generation of plant proteins with cleaner flavor profiles and advanced foaming, gelling, and emulsifying capabilities for mainstream food applications.
- Precision-fermented Dairy Proteins
- Milk-identical proteins made through fermentation create opportunities for customized solubility, heat stability, and nutritional performance across beverages, snacks, and sports nutrition products.
Where This Applies
- Food and Beverage
- High-protein foods and drinks are gaining access to more resilient ingredient systems that support product reformulation, allergen diversification, and reduced environmental impact.
- Agriculture
- Leaf crops such as alfalfa are becoming potential protein feedstocks, connecting regenerative farming models with higher-value ingredient markets beyond traditional animal feed uses.
- Biotechnology
- Fermentation platforms are reshaping ingredient production by enabling scalable, animal-free proteins with tunable functionality for food manufacturers facing commodity volatility.
