Good news: Japanese boffins 3D print what looks like marbled Wagyu beef. Bad news: It's tiny and inedible

(2021/08/27)


Scientists in Japan have 3D printed an approximation of one of the nation's delicacies, Wagyu beef, in an experiment involving bovine stem cells.

A team at Osaka University extracted bovine satellite cells and adipose-derived stem cells from formerly live cows to grow muscle, fat, and blood vessels in a laboratory.

After analyzing a slice of the genuine article for its design, the boffins spent two days 3D printing layer upon layer of their lab-formed tissue, each just hundreds of microns thick, to create a facsimile of Wagyu beef. The overall goal being to investigate "a promising technology for the fabrication of the desired types of steak-like cultured meats."

Details of their experiment were [2]published this week in a paper in the journal Nature Communications.

The end result? A 5mm-by-10mm morsel that looks somewhat like the famous marbled pink flesh yet is inedible due to the manufacturing process. But it's a good first effort.

Cultured meat is nothing new, though it's typically not created in this form. Sergey Brin's famous [8]$250,000 burger was 5oz of cultured meat mush. Now scientists are employing 3D printing mechanics to make more realistic looking meats, and Wagu is a special challenge due to its appearance and structure.

The beef is highly prized because of its "sashi" fat marbling. This leads to it liquefying in the mouth; the fat melts at a temperature lower than your body temperature. The meat is tenderized in some cases by feeding the cows beer or massaging them, and small (by American standards) steaks can run into hundreds of quid or bucks.

"By improving this technology, it will be possible to not only reproduce complex meat structures, such as the beautiful sashi of Wagyu beef, but to also make subtle adjustments to the fat and muscle components,” the paper's senior author Michiya Matsusaki [10]said .

The plan is for people to be able to order cultured meat built to their exact desired levels of fat and muscle tissue. Of course, there's the edibility problem to overcome, though that's apparently fixable. Custom, designer printed steaks could be the next thing for a millionaire's dinner table. ®

"there's the edibility problem to overcome"

Pascal Monett

Obviously, if only for space exploration, it will be necessary to provide a way to grow meat without having a lumbering four-legged creature bumbling about the cabin and sending cow pats floating everywhere.

3D printing the meat ? Not exactly a requirement, but hey, why not ?

Edibility, though, is a requirement. I hope they get that fixed.

Edibility doesn't seem to be a problem for the majority of fast food outlets, they seem to be able to sell ship loads of indeterminate, mostly organic mush.

A few weeks back I was out with friends who invited me to a Mac of some description, whether or not the patty had been a part of a formerly live cow was not discernable by taste, true also of the 'fries' with regard to potatoes.

'fries' with regard to potatoes.

Fixed that for you.

None of which matters when the item is posted on *Bay. The photo can be zoomed in. By the time someone tries to eat what they have bought, the seller will have an entirely new identity

As a vegetarian, the only time I heard of the fabulously expensive Wagyu beef was when ex-pressie Obama served it at his inauguration.

No idea if he served it again at his recent maskless [1]birthday bash , but that was hosted at his $12 million house in homely Martha's Vineyard, so possibly...
