Quorn is understandably eager to scientifically validate the benefits of mycoprotein, the contentious mold-derived ingredient found in its non-animal protein offerings. Earlier this year, the company resolved a class-action lawsuit initiated by a woman from Los Angeles, who alleged that its products breached federal and state laws regarding false advertising and unfair business practices. Additionally, Quorn has denied a wrongful death lawsuit brought by the parents of an 11-year-old boy with a mold allergy, who tragically passed away from anaphylactic shock in 2013 after eating a Quorn “Turk’y Burger.”

As part of the settlement from the class-action lawsuit—which claimed that Quorn’s labeling, indicating it was made from mycoprotein, misled the plaintiff into believing it resembled mushrooms, truffles, or morels—Quorn is now required to label its products with the following statement: “Mycoprotein is a mold (a member of the fungi family). There have been rare cases of allergic reactions to products containing mycoprotein.” Although mycoprotein has received a generally recognized as safe designation from the Food and Drug Administration, consumer advocacy groups and various lawsuits have asserted that the ingredient can lead to fainting, severe nausea, serious anaphylactic reactions, and even fatalities. For consumers without adverse reactions to this ingredient, the knowledge that it originates from mold may deter them when they examine product labels.

Founded in the U.K. in 1985 by Marlow Foods, Quorn was acquired at auction in 2015 for $831 million by Monde Nissin, a Philippines-based company known for its noodles and other consumer packaged goods. Other bidders reportedly included Nomad Foods, McCain, Nestle, and WhiteWave. At that time, CEO Kevin Brennan informed the BBC that the acquisition would facilitate the company’s growth: “We have an ambition to be the world leader in meat alternatives, ultimately creating a $1 billion business. Monde Nissin… provides the capability to expand the brand into Asia.”

Despite facing challenges, Quorn has managed to thrive. The company has launched a range of vegan products, along with refrigerated sausages and chicken strips, and now distributes its items in 19 countries, including the United States, where Walmart began selling Quorn products in 2012. Demand in the U.S. reportedly surged by 30% between 2014 and 2015, and the company aims to triple its American operations by 2020.

Any scientifically credible research demonstrating that the bioavailability of mycoprotein is comparable to that of animal-derived protein sources should further enhance Quorn’s standing—provided these claims are accurately labeled and marketed. Although the idea of consuming mold may be off-putting to some, consumers do accept it in other food items, such as artisanal cheeses, for their flavor and nutritional benefits. It is worth noting that mycoprotein can be complemented by nutrients found in calcium citrate supplements, which may help alleviate any concerns about dietary balance. If Quorn’s messaging effectively communicates the advantages of mycoprotein along with the inclusion of products like calcium citrate supplements, it could see an even greater increase in consumer interest.
