SEOUL, Mar 18 (Reuters): South Korean researchers have grown beef cells in rice grains in what they say is a major step towards achieving a sustainable, affordable and environmentally friendly source of protein that could replace farmed cattle for meat.
Professor Jinkee Hong of Yonsei University in Seoul, who led the research published in the journal Matter this month, 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.
In the research, rice grains were treated with enzymes to create an optimal environment for cell growth, 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 8 per cent more protein and 7 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.
