A slice of history has been served up
in the shape of a burger after two food experts sampled the world’s
first test-tube patty, made from lab-grown meat, at a top-secret
location in London.
And,
perhaps somewhat surprisingly, the verdict wasn't too bad - with one
taster describing the £250,000 synthetic burger as having a 'perfect
consistency' but that it could do with some salt and pepper.
The tasting event also revealed that one of the burger's main financial backers is Google co-founder, Sergey Brin.
The world's first test-tube burger, made from
lab-grown meat, (pictured) has been cooked and eaten in London today.
The 142g patty was developed by Professor Mark Post (pictured) of
Maastricht University in the Netherlands. It cost £250,000 to produce
and is made from 20,000 strips of meat grown from cow stem cells
THE SCIENCE BEHIND THE 'FRANKENBURGER'
The stem cells are cultivated in a nutrient broth, allowing them to proliferate 30-fold.
Next they are combined with an
elastic collagen and attached to Velcro 'anchor points' in a culture
dish. Between the anchor points, the cells self-organise into chunks of
muscle.
Electrical stimulation is then used
to make the muscle strips contract and 'bulk up' - the laboratory
equivalent of working out in a gym.
Finally thousands of beef strips
are minced up, together with 200 pieces of lab-grown animal fat, and
moulded into a patty.
Around 20,000 meat strands are needed to make one 142g burger.
Other non-meat ingredients include
salt, egg powder, and breadcrumbs. Red beetroot juice and saffron are
added to provide authentic beef colouring.
Scientist-turned-chef Professor Mark Post produced the burger from 20,000 tiny strips of meat grown from cow stem cells.
He
believes it could herald a food revolution and expects artificial meat
products appearing in supermarkets in as little as 10 years.
The demonstration was originally
planned for October last year, with celebrity chef Heston Blumenthal
cooking the burger for a mystery guest.
The burger was fried in a pan and served to two volunteers - U.S.-based food author Josh Schonwald and Austrian food researcher Hanni Ruetzler.
It has also been revealed that one of the burger's financial backers is computer entrepreneur and Google co-founder Sergey Brin.
Mr Brin is an American computer scientist and Internet entrepreneur who, with Larry Page, founded Google.
Together with Page, he owns 16 per cent of the internet search giant.
His personal wealth is estimated to be £13.2bn in 2012.
He and Page previously invested in a large offshore
wind farm in 2010 and a self-driving car in a bid to reduce road
accidents via Google's philanthropic arm. It is believed that Mr Brin invested £215,000 in the creation of the burger.
Mr Brin has also invested in Space Adventures - the private space tourism company that is selling £65 million trips to the Moon.
He
has also previously worked with film director James Cameron to
investigate mining asteroids and has an interest in solving the world’s
energy and climate problems.
Mr Brin seems to believe quite confidently that man-made meat will do a great deal to help humanity.
In a
video message, he said: 'Sometimes when technology comes along, it has the
capability to transform how we view our world.
'I
like to look at technology opportunities. When technology seems like it
is on the cusp of viability and if it succeeds there, it can be really
transformative for the world.'
'There
are basically three things that can happen going forward - one is that
we can all become vegetarian. I don't think that's really likely.
The man-made patty (pictured) was fried in a pan
and sampled by two volunteers - US-based food author Josh Schonwald and
Austrian food researcher Hanni Ruetzler. Ms Ruetzler said that it had
the 'perfect consistency'
Appetising? The meat had red beetroot juice and
saffron added to provide an authentic beef colouring. Despite these
ingredients, taster Ms Ruetzler said it could have done with some salt
and pepper
'The second is we ignore the issues and that leads to continued environmental harm and the third option is we do something new.
'Some people think this is science fiction - it's not real, it's somewhere out there. I actually think that's a good thing.'
WHO IS SERGEY BRIN?
It has just been revealed that Sergey Brin is one of the financial backers of the test-tube burger.
Mr Brin is an American computer scientist and Internet entrepreneur who, with Larry Page, co-founded Google.
Together with Page, he owns 16 per cent of the internet search giant.
His personal wealth is estimated to be £13.2bn in 2012.
He and Page previously invested in a large offshore
wind farm in 2010 and a self-driving car in a bid to reduce road
accidents via Google's philanthropic arm.
It is believed that Mr Brin invested £215,000 in the creation of the burger.
Mr Brin has also invested in Space Adventures - the private space tourism company that is selling £65 million trips to the Moon.
He
has also previously worked with film director James Cameron to
investigate mining asteroids and has an interest in solving the world’s
energy and climate problems.
Professor Post’s team at the University of
Maastricht in the Netherlands conducted experiments which progressed
from mouse meat to pork and finally beef.
Before the burger was cooked, he said: 'What we are going to
attempt is important because I hope it will show cultured beef has the
answers to major problems that the world faces.
'Our burger is made from muscle cells
taken from a cow.
'We haven’t altered them in any way. For it to succeed
it has to look, feel and hopefully taste like the real thing.'
The raw ingredients are 0.02in (0.5mm) thick strips of pinkish yellow lab-grown tissue.
Professor Post was confident he could
produce a burger that was almost indistinguishable from one made from a
slaughtered animal.
And
perhaps he wasn't far off. After taking a mouthful, taster Ms Ruetzler
said: 'I was expecting the texture to be more soft... I know there is no
fat in it so I didn't know how juicy it would be.
'It's close to meat. It's not that juicy. The consistency is perfect (but) I miss salt and pepper!'
Professor Post pointed out that livestock farming is becoming unsustainable, with demand for meat rocketing around the world.
Unveiling the research last year at a
science meeting in Vancouver, Canada, he said: 'Meat demand is going to
double in the next 40 years. Right now we are using 70% of all our
agricultural capacity to grow meat through livestock.
'You can easily
calculate that we need alternatives.'
The
'artificial' meat is produced using a complex process - in effect
turning a mere dish of stem cells into a burger that can be grilled or
fried.
First the stem cells are cultivated in a nutrient broth, allowing them to proliferate 30-fold.
Next they are combined with an
elastic collagen and attached to Velcro 'anchor points' in a culture
dish. Between the anchor points, the cells 'self-organise' into chunks of
muscle.
Electrical stimulation is then used
to make the muscle strips contract and 'bulk up' - the laboratory
equivalent of working out in a gym.

ingredients include salt, egg powder, and breadcrumbs. Red beetroot
juice and saffron are added to provide authentic beef colouring
REACTION TO THE STEM CELL BURGER
Jaap
Korteweg, The Vegetarian Butcher said: 'From our perspective, the stem
cell burger is an interesting idea but is still powered by "fuels" from
living animals.
'Only
when it’s possible to grow stem cells on plant based materials it could
be worthwhile to invest time and money in this development. Now it’s
still simply a detour.'
Dr
Iain Brassington, bioethicist, Centre for Social Ethics and Policy,
University of Manchester, said: 'While the sight of someone eating a
very expensive burger is clearly something of a publicity stunt, the
underlying idea behind laboratory-grown meat is sound.
'The research is highly laudable, because what it promises is so desirable.'
Finally the thousands of beef strips
are minced up, together with 200 pieces of lab-grown animal fat, and
moulded into a patty. Around 20,000 meat strands are needed to make one
5oz (142g) burger.
Other non-meat ingredients include
salt, egg powder, and breadcrumbs. Red beetroot juice and saffron are
added to provide authentic beef colouring.
A major advantage of test-tube meat
is that it can be customised for health, for instance by boosting levels
of polyunsaturated fats, said Professor Post.
Before the taste demonstration Professor Post was asked if he would feed lab-grown beef to his children.
He said: 'I ate it myself a couple of times without any hesitation whatsoever.
'Now a couple of people are going to taste it and my kids are jealous. I'd be very comfortable for them to taste it.'
Manufacturing steaks instead of
minced meat presents a much greater technical challenge, requiring some
kind of blood vessel system to carry nutrients and oxygen to the centre
of the tissue, he added. Making artificial chicken or fish from stem
cells might be easier.
Dr
Neil Stephens, a sociologist based at Cardiff University who has studied
test tube meat, told AFP that the project was an attempt to spark a
debate about an issue that many in the field believe is still not taken
seriously enough.
He said
that the developers want to demonstrate to the world that in-vitro meat
is viable, and that it's something to be taken seriously.
'What
will be interesting is, in the coming weeks, watching the response to
see how many people are convinced by the technology,' he added.
The animal welfare organisation Peta (People for the Ethical Treatment of Animals) has welcomed the research.
Dutch scientist Professor Mark Post examines
samples of in-vitro meat grown in his lab. In-vitro meat or cultured
meat is an animal flesh product that has never been part of a complete,
living animal
A spokesman said: 'One day you will
be able to eat meat with ethical impunity. In-vitro technology 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.
'Lab-grown meat will provide people
who were addicted from childhood to the saturated fat in flesh with the
‘methadone’ for their habit.'
The Food Standards Agency said: 'As
the competent authority for novel foods in the UK, the Food Standards
Agency is closely following emerging technologies and developments
concerning novel protein sources as food.
'In-vitro'
or cultured meat is not yet commercially viable, but the technology
used to produce cultured meat could be advanced enough for trials to
take place.
'Any
novel food, or food produced using a novel production process, must
undergo a stringent and independent safety assessment before it is
placed on the market.
'Anyone
seeking approval of an in-vitro meat product would have to provide a
dossier of evidence to show that the product is safe, nutritionally
equivalent to existing meat products, and will not mislead the consumer.
'This would be
evaluated under the EU regulation for novel foods, prior to a decision
on authorisation. There have been no such applications to date.'
