Beef-rice hybrid could solve food crisis

South Korea Scientists at Yonsei University, Seoul, have developed a new sustainable food, beef-rice hybrid, that could help tackle the food crisis and climate change.

The new rice was grown in a university lab, combined with beef muscle and fat cells. The result is a pink rice that could provide a cheaper and more environmentally sustainable meat alternative with a small carbon footprint, Phys.org reported on February 18. The team described the process in the journal Matter.

“Imagine getting all the nutrients you need from cell-cultured protein rice,” said study co-author Park So-hyeon. “Rice already has a high nutrient content, but adding cells from livestock can enhance it.”

The rice grains were coated with fish gelatin to help the beef cells adhere, then grown in a shallow dish for 11 days. The final product contained 8% more protein and 7% more fat than regular rice, and was chewier and crispier. The latest product had a much lower carbon footprint because the production process did not require raising animals, which consumes a lot of water and resources and releases large amounts of greenhouse gases.

For every 100 grams of protein, the beef-rice hybrid is estimated to release less than 6.27 kilograms of carbon dioxide (CO2), while beef production releases eight times as much CO2. If commercialized, it could offer a much cheaper option for consumers. The team calculated the hybrid rice would cost $2.23 per kilogram, while beef costs around $15 per kilogram in South Korea.

Researchers plan to further refine the process before the new rice hits the market to allow for better cell growth, increasing its nutritional value.
