Empowering food companies to make plant-based foods the new norm through clean & functional protein ingredients.

Relying on biomass fermentation, we created Prew:tein®, a clean label protein ingredient with superior functional and nutritional properties. Prew:tein® can reduce or fully eliminate unwanted additives and animal-based ingredients in a large variety of food products.

Introducing Prew:tein®

We offer a vegan and non-novel food protein ingredient, delivering extraordinary functionality across various applications:

Clean solutions

Meat Alternatives

The better solution without the egg

Egg Replacement

Enabling a fully egg-free bakery

Baked Goods

Milk & Cheese without the animal

Dairy Alternatives


With our process, we separate brewer’s yeast into its functional building blocks and then recompose them to meet the needs of our customers. Our unique, gentle processing ensures a clean and fully native protein that can be used in food products to bring all the benefits of animal-based protein functionalities, without sacrificing taste, quality, or nutritional value.

Our Main Pillars

Sustainably Upcycled Materials

Sourced from sidestreams, Prew:tein® outperforms alternative meat and plant proteins in the critical environmental factors carbon, water, and land use.

Safe & Secure

A short and controlled supply chain provides the reassurance of consistent year round supply without seasonal variance in quality or availability.

Supportive & Scalable Partners

We offer the expertise and facilities to enable our customers to successfully develop and test applications, produce in pilot factory conditions and integrate those into their own manufacturing process.

Prew:tein® will allow you to reduce or even eliminate unwanted additives and animal components (e.g., eggs) from your products. By working with us, you will receive the support of our technical team in composing the perfect (c)lean label recipe for your specific application. Ranging from purely functional aspects such as irreversible gelling to taste profiles of neutral or umami flavors, our proteins can be tailored to your needs.

Upcycling Biomass

At ProteinDistillery, we believe in utilizing sidestreams to create a better future. 

Our innovative approach to producing vegan protein leverages the microorganisms found in biomass like, for example, brewer’s yeast from brewing beer, making your industry by-products our input materials. This symbiotic relationship not only allows us to offer high-quality protein ingredients to the market, but it also supports your efforts towards a more circular and sustainable economy. By collaborating with us, you can help reduce waste and drive positive change in the food industry.
