World's first lab-grown burger is eaten in London World's first lab-grown burger is eaten in London

The world's first lab-grown burger has been unveiled at a news conference in London on Monday. The world's first lab-grown burger was cooked and eaten at a news conference in London on Monday.
Scientists took cells from a cow and, at an institute in the Netherlands, turned them into strips of muscle which they combined to make a patty. Scientists took cells from a cow and, at an institute in the Netherlands, turned them into strips of muscle that they combined to make a patty.
Researchers say the technology could be a sustainable way of meeting what they say is a growing demand for meat.Researchers say the technology could be a sustainable way of meeting what they say is a growing demand for meat.
Critics say that eating less meat would be an easier way to tackle predicted food shortages.Critics say that eating less meat would be an easier way to tackle predicted food shortages.
The meat will also be eaten by food critics at the event on Monday. The burger was cooked by chef Richard McGowan, from Cornwall, and tasted by critics Hanni Ruetzler and Josh Schonwald.
Sergey Brin, co-founder of Google, has been revealed as the mystery backer behind the project. Upon tasting the burger, Austrian food researcher Ms Ruetzler said: "I was expecting the texture to be more soft... there is quite some intense taste, it's close to meat, but it's not that juicy. The consistency is perfect, but I miss salt and pepper."
Prof Mark Post of Maastricht University, the scientist behind the burger, said it was made up of tens of billions of lab-grown cells. Asked how when lab-grown burgers would reach market, he said: "I think it will take a while, this is just to show we can do it." She added: "This is meat to me. It's not falling apart."
BBC News has been granted exclusive access to the laboratory where the meat was grown in a project costing £215,000. Food writer Mr Schonwald said: "The mouthfeel is like meat. I miss the fat, there's a leanness to it, but the general bite feels like a hamburger.
Prof Mark Post of Maastricht University, the scientist behind the burger, said: "Later today we are going to present the world's first hamburger made in a lab from cells. We are doing that because livestock production is not good for the environment, it is not going to meet demand for the world and it is not good for animals". "What was consistently different was flavour."
But Prof Tara Garnett, head of the Food Policy Research Network at Oxford University, said decision-makers needed to look beyond technological solutions. Prof Mark Post, of Maastricht University, the scientist behind the burger, remarked: "It's a very good start."

"We have a situation where 1.4 billion people in the world are overweight and obese, and at the same time one billion people worldwide go to bed hungry," she said."We have a situation where 1.4 billion people in the world are overweight and obese, and at the same time one billion people worldwide go to bed hungry," she said.
"That's just weird and unacceptable. The solutions don't just lie with producing more food but changing the systems of supply and access and affordability so not just more food but better food gets to the people who need it."

This might sound a little creepy to some - but Prof Post is no Dr Frankenstein. He's normal and likeable; when he talks about his project there is a gleam in his eye.

He starts with stem cells extracted from cow muscle tissue. In the laboratory, these are cultured with nutrients and growth promoting chemicals to help them develop and multiply. Three weeks later, there are more than a million stem cells which are put into smaller dishes where they coalesce into small strips of muscle about a centimetre long and a few millimetres thick.

These strips are collected into small pellets which are frozen. When there are enough, they are defrosted and compacted into a patty just before being cooked.

The scientists have tried to make the meat - which is initially white in colour - as authentic as possible.

"If it doesn't look like normal meat, if it doesn't taste like normal meat, it's not... going to be a viable replacement," she told me."If it doesn't look like normal meat, if it doesn't taste like normal meat, it's not... going to be a viable replacement," she told me.
Currently, this is a work in progress. The burger to be revealed on Monday will be coloured red with beetroot juice. The researchers have also added breadcrumbs, caramel and saffron, which will add add to the taste. Currently, this is a work in progress.

At the moment, scientists can only make small pieces of meat; larger ones would require artificial circulatory systems to distribute nutrients and oxygen.At the moment, scientists can only make small pieces of meat; larger ones would require artificial circulatory systems to distribute nutrients and oxygen.

Ms Breewood is a vegetarian because she believes meat production to be waste of resources, but says she would eat lab-grown meat.Ms Breewood is a vegetarian because she believes meat production to be waste of resources, but says she would eat lab-grown meat.
"A lot of people consider lab-grown meat repulsive at first. But if they consider what goes into producing normal meat in a slaughter house I think they would also find that repulsive," she said.

In a statement, animal welfare campaigners People for the Ethical Treatment of Animals (Peta) said: "[Lab-grown meat] will spell the end of lorries full of cows and chickens, abattoirs and factory farming. It will reduce carbon emissions, conserve water and make the food supply safer."In a statement, animal welfare campaigners People for the Ethical Treatment of Animals (Peta) said: "[Lab-grown meat] will spell the end of lorries full of cows and chickens, abattoirs and factory farming.

But food writer Sybil Kapoor said she felt "uneasy": "The further you go from a normal, natural diet the more potential risks people can run in terms of health and other issues," she said.
The latest United Nations Food and Agriculture Organization report on the future of agriculture indicates that most of the predicted growth in demand for meat from China and Brazil has already happened and many Indians are wedded to their largely vegetarian diets for cultural and culinary reasons.The latest United Nations Food and Agriculture Organization report on the future of agriculture indicates that most of the predicted growth in demand for meat from China and Brazil has already happened and many Indians are wedded to their largely vegetarian diets for cultural and culinary reasons.
So lab grown meat might turn out to be a technological solution in search of a problem.So lab grown meat might turn out to be a technological solution in search of a problem.
