High Quality Content by WIKIPEDIA articles! Quorn is the leading brand of imitation meat mycoprotein in the United Kingdom. The mycoprotein used to produce Quorn is extracted from the fungus Fusarium venenatum, which is grown in large vats. The product was developed by Rank Hovis McDougall and Imperial Chemical Industries, and launched commercially as the Quorn brand as a joint venture of the two companies under the operating name of Marlow Foods. The brand has been owned by Exponent Private Equity and Intermediate Capital Group since 2011.
