The Protein Brewery B.V.

The Protein Brewery is a Finalist in the 2026 Vitafoods Europe Startup Challenge for the category of Most Innovative Nutraceutical Ingredient.

We are a Dutch food ingredients company advancing sustainable nutrition through biomass fermentation. With 41 employees and an FSSC-22000 certified facility, we are scaling toward 2,500 MT production capacity.

Our hero ingredient, Fermotein®, is a whole-food mycelium grown in under a week. It delivers 50% complete protein (PDCAAS 1.0), 30% prebiotic fiber, essential micronutrients, and naturally concentrated spermidine (0.16%). Preclinical studies show Fermotein® elevates GLP-1 and may increase gut microbial diversity.

We supply the active nutrition, better-for-you foods, and dairy alternatives markets with a positive EFSA safety opinion and fully operational commercial facility.
