Planted pairs fermentation with extrusion to build whole-muscle meat alternatives

What Happened

Swiss startup Planted is scaling a solid-state fermentation platform — combined with extrusion — that structures soy, rice and rapeseed oil into whole-cut products like steaks, steak bites, cold cuts and pastrami rather than just ground/minced formats. The company is now producing 20-25 tons a day combined across its facilities and is targeting production costs of about $2 per kilogram of finished product.

Why It Matters

Whole-cut texture has been the industry's hardest unsolved problem in plant-based meat — most extrusion-only processes top out at ground/minced formats — and getting there at roughly $2/kg addresses the other perennial complaint (price) at the same time, which is why Planted is pushing the platform into cold cuts and pastrami rather than staying in the steak niche.

$1 on raw materials, $1 on processing — a kilogram of whole-cut meat alternative for $2.

FET's Takeaway

Layering solid-state fermentation onto extrusion, rather than replacing it, is the pragmatic move: fermentation builds the fibrous structure and flavor extrusion alone can't deliver, while keeping the existing extrusion capex intact instead of requiring a whole new production line.
