Scientists in South Korea have grown beef cells inside grains of rice in a bid to create meals that’s cheaper and extra eco-friendly than actual cuts of meat.
“Imagine obtaining all the nutrients we need from cell-cultured protein rice,” stated lead creator Sohyeon Park from Yonsei University, South Korea.
“Rice already has a high nutrient level, but adding cells from livestock can further boost it.”
The product is just not but authorised for shoppers, however provides to a rising listing of lab-grown meat and various proteins being developed in a bid to cut back the local weather impression of meat and dairy.
They hope the nutrient-dense rice might present “relief for famine, military ration, or even space food” – if it could possibly be scaled up and if shoppers are keen to strive it.

The staff selected rice because the “host” as a result of its porous construction mimics the three-dimensional setting in animals that cells must develop.
The grains had been coated with fish gelatin to assist the meat cells latch on.
The scientists then added cow muscle and fats cells and left all of it to tradition in a petri dish for 9 to 11 days, earlier than harvesting the ultimate product as a “cell-cultured beef rice”.
The meaty rice incorporates 8% extra protein and seven% extra fats than common rice, discovered the paper, printed on Wednesday in peer-reviewed journal Matter.
It claims the “main ingredients” within the product “meet food safety requirements and have a low risk of triggering food allergies”.
Many various proteins stay extraordinarily costly to provide, however the Korean staff imagine their meaty rice would value round £1.77 ($2.23) per kg, whereas beef is six occasions costlier at £11.85 ($14.88).
They additionally estimate it will launch virtually eight occasions much less greenhouse gases that warmth the local weather, creating 7kg of carbon dioxide per 100g of protein produced, in contrast with 50kg from beef.
Neil Ward, an agri-food and local weather specialist and professor on the University of East Anglia, who was not concerned with the examine, stated: “This line of research holds promise for the development of healthier and more climate-friendly diets in future.”
But the “critical test” will likely be “public appetite for these sorts of lab-developed foods”, he stated.
“With lab-based alternative meats in general, the greatest potential is probably in replacing processed meats rather than prime cuts,” he added.
