Further, "long-term" is a weasel word that is meaningless to people starving right now. The hungry want to hear food is coming, not some hifalutin agriculturally illiterate fantasy thought up by hung over trust fund kids.
Short if giving a specific date and objective success criteria, long-term means never.
> Onego Bio plans to sell Bioalbumen to companies that would then create the food products.
The processed food industry is very cost-sensitive and both industrial egg albumen and various substitutes are already available; if they're not price competitive they'll die quickly.
It doesn't seem at all unlikely that they'lll get to being price competitive quickly. They're producing a single protein with a fungus. There's another well-known example of this; quorn. Quorn's actually a bit more complex in that, once they've produced their protein they need to add stuff to make it palatable, and their processed output still comes in at about the same cost as processed chicken, and generally a bit cheaper than other processed meat. These people seem to be literally just producing albumen, so it's close to an ideal case.
