Grass is greener for healthy, novel protein, say researchers

Grass could be the next source of human-edible protein.

Researchers at the Technical University of Denmark have extracted food-grade protein from grass (which is normally not digestible by humans) and have even made a grass protein bar. While the details are being kept private as the researchers may patent the process, grass protein holds promise as a relatively eco-friendly option. The byproducts of the extraction process could still be fed to cattle.

Europe is the world's second-smallest continent by surface area, covering just over 10 million square kilometres or 6.8% of the global land area, but it is the third-most populous continent after Asia and Africa, with a population of around 740 million people or about 11% of the world's population. Its climate is heavily affected by warm Atlantic currents that temper winters and summers on much of the continent. In the European Union, farmers represent only 4.7% of the working population, yet manage nearly half of its land area.
