Mycoprotein is the food material derived from the fungus Fusarium Graminearum. The fungus is often found in soil but can be found parasitizing wheat and other cereals.

Mycoprotein is fermented in large vats, then processed. It is used primarily in meat substitutes such as Quorn or as a salt substitute.

The United States National Institute of Health has documented violent reactions from people with mold allergies who consume mycoproteins. Mycoprotein manufacturers claim that there are more people who suffer allergies to things like peanuts, soy, and wheat gluten, yet no-one suggests banning them.
