Don’t have a cow: Israel’s Remilk serves up dairy products made without animals

19 28 140

Israeli startup Remilk hopes to be the first company in the world to bring real dairy milk products to market without needing a single cow in the process.

“Relying on animals to make our food is no longer sustainable,” said Aviv Wolff, who co-founded the startup up last year. “The implications of animal farming are devastating for our planet.”

The time has come, he said, for “a new revolutionary invention that will enable the transition to a food system that takes no more than what our planet can give.”

The technology Wolff and his scientist partner Ori Cohavi have developed produces milk proteins that are “chemically identical” to those present in cow-produced milk and dairy products, explained Wolff in a phone interview. That essentially means they are dairy products with dairy proteins, minus the cows. A mozzarella cheese ball made with Remilk’s milk proteins (Courtesy)

The two entrepreneurs mapped out the chemical composition of milk, assessed the fat, lactose and sugar in the liquid, and determined that the key ingredient to making milk is the proteins.

They thus set out to recreate the proteins by taking the genes that encode them and inserting them into a single-cell microbe, which they manipulated genetically to express the protein “in an efficient and scalable way,” said Wolff. Using a microbial fermentation process, they increased the number of proteins, which they then dried into a powder.

“We’re making dairy products that are identical to cow-milk products, with the same taste, texture, stretchiness, meltiness, with no cholesterol and no lactose,” he said. “We’ve basically ported the whole mechanism of producing milk into a single-cell microbe. We don’t need the ‘rest of the cow,’ and we surely don’t need to spend resources in the process of creating a........
