LAB-GROWN MEAT

EVERYTHING YOU NEED TO KNOW ABOUT A FUTURE WHERE YOU CAN HAVE YOUR STEAK AND EAT IT…

- AMY FLEMING

It wasn’t long ago that the idea of the meat on our plates coming from vast stainless steel bioreactors, rather than farmed animals, seemed like science fiction. The notion has gone through numerous rebrands since its early positing as ‘vat meat’, which triggered unappealing visions of high-tech Spam. ‘Lab meat’ came next, as scientists perfected the recipe in small beakers in laboratories. Then came the more appetising-sounding ‘cultured meat’, as investment from high-profile individuals rocketed and producers positioned these products as having been brewed, just like beer. Now, ‘cultured meat’ has evolved to ‘cultivated meat’, which is the preferred term used by CEOs in the industry.

Whatever you choose to call it, with the future of global food security in question, and farmed meat a key culprit in climate breakdown, slaughter-free meat is starting to look increasingly like the future of food.

HOW IS THE MEAT MADE?

Rather than being part of a living, breathing, eating and drinking animal, cultivated meat is grown in anything from a test tube to a stainless steel bioreactor. The process is borrowed from research into regenerative medicine, and in fact Prof Mark Post of Maastricht University, who cultured the world’s first burger in 2013, was previously working on repairing human heart tissue. Cells are acquired from an animal by harmless biopsy, then placed in a warm, sterile vessel with a solution called a growth medium, containing nutrients including salts, proteins and carbohydrates. Every 24 hours or so, the cells will have doubled.
