I have been trying all different types of milk alternatives like oat milk, almond milk etc. But none of them taste similar to cow’s milk. I know a lot of it has to do with familiarity with the milk I’ve been drinking all my life. But I want to understand why there has not been a lab-created cow’s milk yet.
In: Biology
There has been, kinda sorta. The process is just too expensive to be able to sell it as “milk”, so it’s being used in higher sale-price milk products like ice cream.
A company called Perfect Day uses fungus to create the proteins found in cow milk, like whey proteins and casein. Their ingredient was used by Brave Robot for ice cream sold in stores, and Smitten in stand-alone ice cream shops.
People who want a vegan milk are ok with other kinds that don’t taste exactly like it. People who want milk taste but are lactose intolerant have things like lactaid. There’s not really a market for what you’re looking for.
I’ve been drinking non dairy milks for years now, and now when I drink regular milk it tastes weird to me and I don’t like it.
Great question!
Many have tried.
It’s fairly easy to make components of milk (proteins such as casein or sugars like lactose) using bacteria or yeast. We did something like this as a first year university science experiment 20 years ago.
But making whole milk that feels like a satisfying replacement is super hard. We can’t do that because milk is a complex mix of different biological processes, every bit as complex as human milk.
Making milk components might be easy enough – but super hard to do at industrial scale. As an example, there was a well-publicised effort around 10 years ago by some California bio-hackers to make milk proteins using yeast (modifying the yeast cells to produce milk proteins) as a step towards making replica cheese that would be vegan. They made some cheese, raised a lot of money, but it wasn’t commercially viable… it was way tk expensive and only limited quantities could be made.
I’ve often thought the same thing… We feed hay to cows and they produce milk. One goes in and the other comes out. How is it that we haven’t been able to create a machine that takes in hay and spits out milk? Not to imply that it’s that simple but… What about that process is it that we cannot reproduce synthetically?
It’s the proteins that are the problem or the barrier. Mimicking them or mass producing them on such a large scale is is a “biotechnological challenge”. It’s usually done by giving microorganisms a genetic code that enables them to produce real milk proteins through a precision fermentation process – but this is difficult to do on the large scale required for manufacturing. But there is some progress being made.
