The £250,000 Hamburger In London!

*First test tube-grown beef will be served in London restaurant this week*
The world’s first test tube burger will be served at an exclusive London
venue this week - with a price tag of £250,000.
The 5oz burger is made of synthetic meat grown from the stem cells of a
cow.
Scientist Mark Post, from Maastricht University, believes the development
could help solve problems in the meat industry.
He said 'Right now, we are using 70 per cent of all our agricultural capacity
to grow meat through livestock. You are going to need alternatives. If we
don’t do anything meat will become a luxury food and will become very
expensive.’
A four-step technique is used to turn stem cells from animal flesh into a
burger.
First, the stem cells are stripped from the cow’s muscle.
Next, they are incubated in a nutrient broth until they multiply many times
over, creating a sticky tissue with the consistency of an undercooked egg.
This ‘wasted muscle’ is then bulked up through the laboratory equivalent of
exercise - it is anchored to Velcro and stretched.
Finally, 3,000 strips of the lab-grown meat are minced, and, along with 200
pieces of lab-grown animal fat, formed into a burger.
The process is still lengthy, as well as expensive, but it could take just six
weeks from stem cell to supermarket shelf.
His work is funded by the Dutch government, as well as an anonymous
donation of 300,000 euros - but it remains to be seen, however, whether the
pioneering development will find favour with a public that likes to think of
its chops, steaks and sausages as having their roots in nature, rather than in
test-tubes.
He first attempts involved mouse burgers. He then tried to grow pork in a
dish, producing strips with the rubbery texture of squid or scallops, before
settling on beef.
His burger consists of about 20,000 thin strips of cultured muscle tissue.
The cell-grown burger is produced with materials — including fetal calf
serum, which used to grow the cells — that will eventually be replaced by
materials not orginating from animals, the New York Times reported.
