Finnish startup Solar Foods has come up with a way to produce a protein-rich food called Solein from electricity, water and air, by using an environment-friendly process similar to brewing beer.
Described as the world’s most environmentally friendly protein, Solein is is made by applying electricity to water to release bubbles of carbon dioxide and hydrogen. Living microbes are then added to the liquid to feed on the carbon dioxide and hydrogen bubbles and produce the Solein, which is then dried to make the powder. It’a natural fermentation process similar to beer brewing, but it requires a special reactor that reportedly resembles a hurricane lantern. The dried Solein has a protein content of 50 percent and looks and tastes just like wheat flour. It can be used in all kinds of diets and can be 3D-printed for added texture.
