A Finnish research team has taken a step towards the future of food by developing a method for producing food from electricity. If scaling it up proves to be successful, it could help in the fight against world hunger and climate change.
The researchers created a batch of single-cell protein that is nutritious enough to serve for dinner using a system powered by renewable energy. The process requires electricity, water, carbon dioxide, and microbes.
After exposing the raw materials to electrolysis in a bioreactor, a powder forms consisting of protein and carbohydrates. Textures can also be changed by altering microbes.
