Biomass Fermentation Displaces Extruded Plant Protein Formats
Mycoprotein and microbial biomass proteins arrive with fibrous structure already formed, which removes the texturisation step that extrusion performs imperfectly and that requires methylcellulose and other binders to hold together. Quorn built the category over decades, and newer producers have added capacity across Europe and North America. The commercial advantage is a shorter ingredient declaration that answers ultra-processed criticism directly rather than arguing with it. Fermentation also decouples protein supply from crop cycles and land, though capital intensity remains high and utilisation across the sector sits well below design. Nobody has yet reached the cost of extruded protein.
