Quorn

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.

Quorn is produced as both a cooking ingredient and a range of ready meals. It is sold (largely in Europe, but also in other parts of the world) as a health food and an alternative to meat; after changing production methods to ensure that only free-range eggs were used, the Vegetarian Society gave the product a seal of approval.

When Quorn was introduced into the United States in 2002, the Center for Science in the Public Interest expressed multiple concerns over the product. Much of the concern from CSPI and others was over the original labeling of Quorn as a "mushroom based" product.
