Why Buy the Cow When You Can Biofabricate the Milk for Free?https://www.engadget.com/2017/09/29/why-buy-the-cow-when-you-can-biofabricate-the-milk-for-free/https://www.nytimes.com/2019/08/02/science/lab-grown-milk.html Move Over, Fake Meat—Cow-Less Milk and Cheese Are On the Wayhttps://about.bgov.com/news/move-over-fake-meat-cow-less-milk-and-cheese-are-on-the-way/Dairy tastes like dairy thanks to two key proteins, casein and whey protein. Researchers at several start-up companies have begun producing these proteins in the lab, with the aim of creating a new grocery store category: cow-free dairy.Their process is loosely comparable to the way
Impossible Foods or
Beyond Meat makes meatless burgers. Microbes, such as yeast, are given the genetic instructions to produce the dairy proteins. The microbes are then cultivated en masse, with nutrients added and the temperature adjusted. Eventually the organisms start churning out large quantities of the proteins, and these are isolated and added to various recipes.
Hundreds of thousands of metric tons of whey and casein are consumed in the United States each year, virtually all of it produced by dairy farms. Proponents of lab-made milk see the product appealing to dairy lovers broadly, while satisfying concerns about animal welfare and environmental sustainability. But to make a real impact on the planet, and eliminate the carbon emissions from all those belching cows, a great many microbes will need to be corralled.

Perfect Day (originally Muufri), may be the furthest along in perfecting a recipe for lab-made dairy. The company produces whey protein and mixes them with other ingredients found in traditional dairy — fats, carbohydrates, calcium and phosphates. In early July, a limited-edition ice-cream batch was released, with flavors including chocolate, vanilla salted fudge and vanilla blackberry toffee; it quickly sold out.
... The dairy substitute is nutritionally identical to cow’s milk and tastes just like it. In fact, while
Perfect Day Foods at least considers its product “
vegan” and lactose-free (since lactose is a sugar found only in mammals’ milk), federal law actually requires them to put “
contains milk” on any labeling because its protein is identical to cow’s milk on a molecular level and could cause allergies.
The challenge is scaling up. Perfect Day plans to sell its lab-made whey to ice cream-makers, dairy companies and restaurants rather than directly to consumers. It has also partnered with agriculture giant Archer Daniels Midland, with its industrial-scale fermentation infrastructure, to try to meet market demand and reduce the cost of producing proteins.Perfect Day co-founders Ryan Pandya and Perumal Gandhi, who started the company in 2014, said they were eager to produce a product that could make a “
sizable impact” on factory farming, unlike the pace of plant-based companies.
