How do you make animal-free dairy protein?

Perfect Day has developed a type of microflora that can ferment simple plant ingredients to produce the milk proteins, casein and whey, historically found in milk. We started with a natural type of microflora known to produce large amounts of pure protein for food and gave this flora a “blueprint” that allows it to ferment sugar and create real dairy protein. This is the very same blueprint, in the form of DNA, which cows use every day.

Our protein is made using safe and proven fermentation techniques similar to how many common food components like vitamins, probiotics, enzymes, and natural flavors are made.


Our process is much cleaner and more resource-efficient than animal farming, and it’s the cornerstone of our new approach to dairy. To learn more, check out our process page.
