For a $330,000 burger, taste testers thought the flavor fell a little flat.
The hefty price tag, however, wasn't for some fancy, rare cut of meat. In fact, this meat had never so much as mooed in a previous life: It was beef grown in a laboratory.
Dutch scientists Monday unveiled their ambitious research project, years in the making, with a public taste test of their cultured beef in London.
Volunteer tasters sampled hamburger made from the lab-grown beef made from stem cells. Scientists hope it can one day alleviate a food crisis as the world's population swells and help combat climate change.
To make the meat, scientists at Maastricht University in the Netherlands used muscle stem cells from two organic cows and combined them with a nutrient solution. The muscle cells then grew into strands of meat. It takes 20,000 strands to make a 5-ounce burger.
Taste testers said the meat lacked the fat of a conventional burger, making the taste a little underwhelming, the Associated Press reported.
But with a bit more tinkering, Mark Post, who led the project, said that could be resolved.
In a YouTube video of the event, the taste testers said the meat had the consistency of conventional beef and it tasted lean.
