‘Beef rice’ seen as potential protein source for future

South Korean researchers have grown beef cells in rice grains in what they say is a major step toward achieving a sustainable, affordable and environmentally friendly source of protein.

Professor Jinkee Hong of Yonsei University in Seoul, who led the research, said the “beef rice” is the first product of its kind. It uses grain particles as the base for cultivating animal muscle and fat cells.

Why it matters: The beef rice has a greater amino acid profile than traditional rice and could improve the nutrition of people living in areas where livestock production is not practical.

In the research, rice grains were treated with enzymes to create an optimal environment for cell growth and then infused with bovine cells that are cultivated to achieve the final hybrid product, which resembles a pinkish grain of rice.

The Yonsei team is not the first to work on lab-grown meat products. Companies around the world have launched cultivated meat; one of the latest involves plant-based chicken and eel cultivated from a soy base, marketed in Singapore.

Hong’s team said rice has an advantage in terms of safety relative to soy or nuts because fewer people are allergic to it.

“If successfully developed into food products, cultured beef rice could serve as a sustainable protein source, particularly in environments where traditional livestock farming is impractical,” he said.

The beef rice contains approximately eight per cent more protein and seven per cent more fat than conventional rice. Hong noted the protein is 18 per cent animal-based, making it a rich source of essential amino acids.

Priced at about US$2 per kilogram and with a far smaller carbon footprint than traditional beef products, cultured beef rice could compete on grocery shelves, Hong said.

Challenges remain from a technical standpoint and in terms of winning customers with flavour and texture.

Keum Dong-kyu, who recently sampled the beef rice at a Korean barbecue restaurant in Seoul, said the idea is innovative, “but honestly, I don’t think it can replicate the juiciness or texture of real beef.”

Christian Krammel, who was visiting from Germany, was more positive.

“Now, it does not compare to beef yet, but as I see the research is in early stages, I would say it’s a great way forward.”
