For years, lab-cultured meat has been touted as the subsequent sustainable protein various. But it surely’s but to seem in supermarkets. So what’s taking place behind the scenes? Constructive Information speaks to the CEO of an organization pioneering this innovation
It appeared just like the form of low-cost burger served up at a roadside greasy spoon, however when Cornish chef Richard McGeown slid his puck of floor beef right into a scorching pan of oil again in 2013, it marked a second in culinary historical past.
McGeown’s patty was the primary on the planet to be grown in a laboratory and – at an eye-watering price of £215,000 – by some margin additionally the costliest.
However that was nearly a decade in the past, and whereas McGeown’s stunt served as a tantalising style of issues to return, the world continues to be ready for the sustainable meals innovation that would assist save our planetary bacon. Scientists have finished a fantastic job of promoting us the concept of lab-grown meat, so why has it nonetheless not discovered its manner into our kitchens?
“I’d say cultured meat is far more superior than many of the public is aware of,” enthuses Märt-Erik Martens, CEO of Estonian startup Gelatex, a significant participant on this rising market. “Firms are ramping up; they’ve pilot manufacturing services both being arrange or already operational. The important thing parts are kind of developed and in place. However you need to keep in mind – you possibly can’t have a look at this in the identical manner as plant-based various meats, as a result of it’s completely completely different. It’s far more difficult.”
Gelatex gained the 2019 Inexperienced Alley Award – an award scheme that nurtures round financial system startups – with a novel artificial leather-based spun from gelatine nanofibres. Two years in the past, it pivoted to assist cultured meat producers overcome a significant manufacturing headache.
Lab-grown meat is made by rising muscle tissue that’s cultivated from a tiny pattern of stem cells harvested from a dwell animal. Utilizing plant-based polymers rather than gelatine, Gelatex created an edible ‘nanofibre cloth’, which gives a cotton candy-like textural ‘scaffold’ for these cultured meat cells. With no scaffold, the completed dish would look much less like a first-rate slab of sirloin, and extra like a mushy dollop of Brussels pâté.
Though Martens is reluctant to call names, he says he’s working with eight out of 10 of the world’s prime cultured meat producers. However whereas his nanofibres have been used efficiently to prototype lab-grown hen fillets and shellfish, these novel meals want the rubber stamp of presidency approval earlier than they are often offered to the general public.
“Regulation is the principle problem,” says Martens. “This can be a utterly new strategy to producing meat, so you possibly can’t take laws from standard agriculture and apply them to cultured meat merchandise. Fortunately that is being labored on in quite a few completely different areas.”
Main the way in which is Singapore. The south-east Asian nation greenlit the sale of cultured meat to the general public in 2020, and US startup Eat Simply trialled its lab-grown hen bites there the next 12 months. They had been priced at a loss-making $16 (£14.30) a portion, round a 3rd of the price of rising a single nugget.
And therein lies one other barrier.
Worth parity with standard meat can solely be realised by scaling up manufacturing, and the funding producers have to supersize key applied sciences – such because the bioreactors wherein meat is grown – will solely come following the approval of meals regulators.
“It’s just like the hen and the egg,” Martens quips. “Services want to have the ability to produce tonnes of product. The expertise is sort of there, however the scale isn’t. That is tissue engineering on an industrial scale, one thing that’s by no means been finished earlier than.”
Regulators within the US, Israel and China are sizzling on Singapore’s heels. Within the close to future, maybe inside the subsequent 12 months or so, Martens believes we’ll start to see cultured meats seem in choose, unique eating places, priced at a premium.
“As they need to be, as a result of they actually take a whole lot of effort to make,” he notes, including that it might be one other 4 to 5 years earlier than we’re including mass-produced cultivated meats to our grocery store trollies.
Typical mud-and-wellies farmers are understandably cautious of being elbowed out by the speedy advance of dazzling new expertise. Environmentalist George Monbiot provoked rancour along with his e-book, Regenesis, which lauds one other lab-based answer for rising meals proteins – precision fermentation. As an alternative of culturing stem cells, it makes use of genetically modified yeasts and micro organism to develop lookalike meat analogues.
Nevertheless some proponents of cultured meat insist farmers will nonetheless have an important function to play on this courageous new world. Seren Kell, science and expertise supervisor on the Good Food Institute suppose tank, is one in all them.
“Cultivating meat cells nonetheless wants enter from agriculture – crops like tobacco, soy and chickpea are damaged down and used as substances in cell tradition media,” she says. “Farmers can and will play a key function within the transition in direction of what can be a extra sustainable meals provide.”
Inevitably, rising crops to supply bundles of cells as an alternative of complete animals means decreasing the burden of agriculture on general land use.
“That’s an enormous alternative,” says Kell. “You’re liberating up land for issues like carbon seize and storage, rewilding or extra nature-friendly practices like regenerative and natural agriculture. Farmers could be a half or lead on any of these issues – however do want governments to help them, assist them adapt and establish what that function might seem like.”

The prize, says Martens, is “the holy grail of meat options” when it comes to sustainability.
Half of the world’s liveable land is used for agriculture, and over three-quarters of that’s turned over to livestock manufacturing – both for grazing land or to develop animal feed – whereas meat accounts for 60 per cent of all meals business greenhouse gases. In contrast, cultured meat might, in idea, be grown in a laboratory powered by renewable vitality, liberating up tens of millions of acres.
On the similar time, the sterile circumstances wanted to develop meat cell cultures would largely put off the necessity for the huge portions of antibiotics at present pumped into cattle, estimated at nearly 70 per cent of the worldwide complete.
“If you consider it, there hasn’t been a significant innovation in meat manufacturing for 10,000 years, not since we started herding animals as an alternative of searching them,” says Martens, as he embarks on a €15m (£13.2m) funding spherical to finance a pilot manufacturing facility.
“What this unlocks when we have now the dimensions is probably the most sustainable meat within the historical past of humankind.”
Or not less than, one in all a mixture of options for a extra sustainable meals future.
