The world's first lab-grown in-vitro beef burger, cultured from cattle stem cells, the first example of what its creator says could provide an answer to global food shortages and help combat climate change, will be fried in a pan and tasted by two volunteers.
The burger is the result of years of research by Dutch scientist Mark Post, a vascular biologist at the University of Maastricht, who is working to show how meat grown in petri dishes might one day be a true alternative to meat from livestock.
The meat in the burger has been made by knitting together around 20,000 strands of protein that has been cultured from cattle stem cells in Post's lab.
The tissue is grown by placing the cells in a ring, like a donut, around a hub of nutrient gel.
To prepare the burger, scientists combined the cultured beef with other ingredients normally used in burgers, such as salt, breadcrumbs and egg powder. Red beet juice and saffron have been added to bring out its natural colors.
Hanna Tuomisto, who conducted the study at Oxford University's Wildlife Conservation Research Unit, found that growing meats in-vitro would use 35 percent to 60 percent less energy, emit 80 percent to 95 percent less greenhouse gas and use around 98 percent less land than conventionally produced animal meat.
