Onego Bio's Fermented Egg Protein Gets Its First Baking Job in Zen Waffles

What Happened

Finnish precision-fermentation startup Onego Bio will supply Brooklyn's Zen Waffles with Bioalbumen, a recombinant ovalbumin grown in Trichoderma reesei that matches chicken egg white's amino acid sequence and scores a perfect 1.0 PDCAAS. The shelf-stable powder is claimed to provide structure for a tender interior and support browning for a crisp exterior in the waffles.

Why It Matters

Egg white's functional role in baking — structure and browning — is exactly what plant proteins have struggled to replicate; a fermented protein with an identical amino acid sequence and top protein-quality score removes the usual formulation compromise rather than papering over it with additives.

FET's Takeaway

The claim worth watching is functional, not nutritional: browning and crumb structure in an actual waffle iron is a harder bar than hitting a protein number on a label, and it's the test that decides whether this scales past one bakery partner.
