“Myco” refers to things related to fungi but mycoprotein is not from mushrooms. Rather, it’s produced by a thread-like fungus that’s found in the soil. The official name is Fusarium venenatum.

Mycoprotein is a relatively new thing. It was literally cooked up back in the 1980s by some British industrialists who were worried about a global food crisis--specifically, they were worried that we would be unable to produce enough protein to sustain a growing population. By trial and error, they came up with a process in which the spores are fermented in big vats, with glucose as a food source and various other nutrients. The resulting biomass resembles a sort of fibrous dough that’s high in protein but also high in fiber.  It also has a somewhat meat-like texture and a faint mushroomy smell.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
