The signal
Fermentation-made dairy and egg proteins are already in some ice creams, cheeses and baked goods. They remain more expensive than animal-based versions and production capacity is limited.
Where it could lead
If these proteins become as cheap as the originals, food companies could swap them in quietly at huge scale — changing dairy and egg farming without consumers needing to change what they eat.
Evidence that would strengthen the case
- Prices reach parity with animal-based proteins
- Large food manufacturers use them in mainstream products
- Big new fermentation facilities come online
What could prevent it
- Costs stay high because of expensive equipment and feedstock
- Labelling fights or bans in key markets
- Consumers reject “lab-made” food
