Vivitein™ BLG

Change the game with the New Standard of Protein.

Vivitein™ BLG is a superior protein ingredient, over 90% pure in beta-lactoglobulin (BLG), made by precision fermentation. It gives brands a previously impossible mix of high protein concentration in applications, superior sensorials, and a strong fit with modern consumer lifestyles. Vivici positions it as the New Standard of Protein.

Vivitein™ BLG is produced through precision fermentation rather than extracted from dairy. The result is a beta-lactoglobulin protein ingredient that is bio-equivalent to milk-derived beta-lactoglobulin. It delivers unique nutritional and functional benefits, while also offering a more stable and reliable supply chain, providing the protein performance consumers expect, with clear advantages for finished products.

It enables high protein concentration in applications, is high in BCAAs and leucine, and is rapidly absorbed to fuel and build muscle. Because it is fermentation-derived rather than extracted from dairy, it is lactose-free, vegan-friendly, and cholesterol-free. It also unlocks superior sensorials that conventional dairy proteins struggle to match, including a lighter mouthfeel and no chalky aftertaste.

Nutritionally, Vivitein™ BLG is a complete protein. It enables high protein concentration in applications, is high in BCAAs and leucine, is rapidly absorbed to support muscle protein synthesis and recovery, while being lactose-free and cholesterol-free. Functionally, it is a formulator's protein.

‍

It is highly soluble, which enables crystal-clear, high-protein beverages, delivers low astringency for a lighter and more refreshing taste, and offers strong heat stability for reliable performance across processing and formats. Together these properties let brands create products that were previously out of reach.

Vivitein™ BLG delivers superior sensorials. Its high solubility and low astringency unlocks crystal-clear protein drinks with a light, refreshing mouthfeel, an exciting range of water-based flavors, and no chalky aftertaste with a low viscosity contribution and strong heat stability for reliable performance across processing and formats.

‍

This makes it ideal for premium, refreshment-led formats where taste and clarity set products apart.

Vivitein™ BLG is built for premium active-nutrition formats. Its clarity, light mouthfeel, and high protein concentration across formats are best leveraged in formats such as protein shots delivering 25g of protein in a 100 ml format, protein sodas, and clear protein beverages.

‍

It also performs in ready-to-mix protein powders that deliver rapid absorption and the BCAAs and leucine needed to fuel muscles.

Vivitein™ BLG enables high protein concentrations across formats. In a compact protein shot, for example, it can deliver 25g of premium protein in a 100 ml serving, with clean nutrition, a light mouthfeel, and no shaking required before use.

Yes. Vivitein™ BLG is made by precision fermentation and no animals are involved in its production, which is what makes it a vegan-friendly ingredient and flexitarian-friendly. It is also lactose-free and cholesterol-free, which aligns with the values of consumers reducing their consumption of animal products while still delivering the protein performance of dairy protein.

‍

It requires allergen labeling as “Milk”. Because the protein is bio-equivalent to milk-derived beta-lactoglobulin, anyone with a milk allergy could react to it in the same way. Allergen labeling as “Milk” is therefore required to protect those consumers, even though the ingredient itself is not derived from an animal.

Precision fermentation ensures supply stability, predictable pricing, and consistent quality, which helps brands plan with confidence amid the volatility of conventional dairy supply chains. It also unlocks product innovation and supports a smooth path to market, so brands can move quickly on new formats and ideas.

Vivitein™ BLG is for agile innovators creating premium active-nutrition products for consumers who want it all: protein performance, superior sensorials, and products that suit their lifestyles and values. It is well suited to brands developing beverages, powders, and shots that set a new standard in their category.
