Korean Researchers Create “Meat-Rice:” Engineered Rice Fused Will Cell-Cultured Meat

The following report is by Nature:

The study, published today in Matter, uses manufacturing methods similar to those for other cultured meat products, in which animal cells are grown on a scaffold in a laboratory, bathed in a growth medium. Using rice as the scaffold has the benefit of adding nutrition to the rice, with the beef–rice having a slightly higher fat and protein content than standard rice.

The team of South Korean researchers behind the project hopes that the beef–rice will find use as a supplement for food-insecure communities or to feed troops, and will reduce the environmental impact of rearing cattle for beef.

Finding alternative protein sources or making conventional livestock production more efficient is critical. It’s probably one of the most important things facing the future of the human race.

Jon Oatley, an animal biotechnologist at Washington State University in Pullman, said

That need has spurred a variety of cultured meat projects in recent years, ranging from fully fledged salmon fillets to products similar to minced beef. As of last year, only the United States and Singapore had approved the sale of lab-grown meat.

Co-author Sohyeon Park, a chemical engineer now at Massachusetts General Hospital in Boston, says that the team tried to grow beef cells directly in the porous crevices of a grain of rice, but the cells didn’t take well to the grain. Instead, the researchers found that coating the rice in fish gelatin and the widely used food additive microbial transglutaminase improved cell attachment and growth. After glazing uncooked rice grains with the gelatin–additive mix, the team seeded the grains with bovine muscle and fat cells. Then, the cells sat in the growth medium for around a week.

After the culturing period, Park washed and steamed the beef-infused rice as she would conventional rice. “It was definitely different from regular rice,” she says. “It was more nutty and harder.”

The nutritional content is also different, but only marginally so. A 100-gram serving of the hybrid rice contains 0.01 grams more fat and 0.31 grams more protein, a 7% and 9% change respectively. According to the study, it’s essentially the same as eating 100 grams of rice with one gram of beef brisket — less than half a teaspoon. That’s because the beef-cell content is low, and the cells probably form just a film over the rice, says John Yuen, a tissue engineer and molecular biologist at Tufts University in Medford, Massachusetts. He says the nutritional content could be boosted by increasing the number of bovine cells on the rice grains.

It’s something the team is looking into, says Park. In particular, she hopes to improve the fat content of the rice, which could be tricky, because fat cells don’t grow as well as muscle cells. In addition to boosting the bovine content of the hybrid rice, researchers would need to keep the price low if the product were commercialized, so that food-insecure communities could benefit from it. The team estimates that 1 kilogram of the rice as it’s made now would cost US$2.23, comparable with normal rice ($2.20 per kilogram) and much less than beef ($14.88 per kilogram). And the study estimates that hybrid rice will have a lower emissions footprint than farmed beef.

If production can be scaled up and kept affordable, Oatley says, the hybrid rice could be a cheaper, more efficient source of nutrition than large pieces of lab-grown meat, such as patties or steaks.

Yuen also finds the concept exciting.

The idea seems really cool, that you can just have one rice and then take care of everything.

AUTHOR COMMENTARY

This grotesque slop and vile is the type of crap the ruling elites want us to consume; but don’t eat the real stuff, it’s unhealthy and bad for the environment, even though proper sustainable stewardship manages and strengthens the land. “Delight is not seemly for a fool” (Proverbs 19:10(a)).

[1] Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; [2] Speaking lies in hypocrisy; having their conscience seared with a hot iron; [3] Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.

1 Timothy 4:1-3

[7] Who goeth a warfare any time at his own charges? who planteth a vineyard, and eateth not of the fruit thereof? or who feedeth a flock, and eateth not of the milk of the flock? [8] Say I these things as a man? or saith not the law the same also? [9] For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen? [10] Or saith he it altogether for our sakes? For our sakes, no doubt, this is written: that he that ploweth should plow in hope; and that he that thresheth in hope should be partaker of his hope. (1 Corinthians 9:7-10).
