The foodtech will use yeast as hosts to initially produce casein and whey protein, two of the main proteins found in milk.
Bioreacted casein would be a HUGE leap for cow-free dairy. I remember when Perfect Day started up they were having too much trouble producing casein, so their products couldn't be used to make stringy or melty cheese.
As a former cheese addict who developed severe lactose intolerance, I'll just be waiting here for the synthetic cheese. (Please. I miss pain-free cheese so much 😭)
