Quorn (trademark) is a mold fungus protein from the Fusarium family, discovered in the town of Marlow in Great Britain in the 1970s.

Quorn has a meat-like taste and is fermented in large sterile tanks prior to purification and processing into usable chunks. It is increasingly popular in Europe as a substitute for meat, especially among vegetarians.

Marlow Foods owns the patents on the production technology and controls all Quorn production. Marlow Foods is in turn owned by Astra Zeneca.

Contrary to popular belief, Quorn is not genetically modified, it is used in the state in which it was discovered. The different tastes and forms of Quorn are results of industrial processing of the raw fungus.
