Why is Quorn not vegan? Unpacking the ingredients and diet implications

4 min read

Over 50 years ago, Quorn introduced mycoprotein, a fungi-based protein source, yet not all products are vegan. The simple reason is that many vegetarian Quorn products use animal-derived ingredients, specifically egg whites, as a binding agent.

Quick Summary

Many Quorn products are not vegan because they use egg whites as a binding agent for texture. Quorn also manufactures a separate range of products that are clearly labeled as vegan, using plant-based binders instead.

Key Points

  • Egg White Binder: Many vegetarian Quorn products contain egg whites, a non-vegan ingredient, to help bind the mycoprotein.

  • Vegan-Specific Range: Quorn produces a separate line of products explicitly labeled 'vegan' that use plant-based binders like potato protein instead of eggs.

  • Check for Labeling: The most reliable way to identify a vegan Quorn product is by checking for the 'Vegan' label or the Vegan Society logo on the packaging.

  • Mycoprotein is Vegan: The main ingredient, mycoprotein, is a fungi-derived protein that is vegan on its own; it's the added ingredients that matter.

  • Not a Plant: Mycoprotein is not derived from plants, but from a fungus, which belongs to its own kingdom separate from plants and animals.

  • Past Practices: While some older products were tested on animals, Quorn stopped all animal testing in 1995.

The Core Reason Quorn Isn't Always Vegan

At the heart of the matter, the primary ingredient in all Quorn products is mycoprotein, a protein derived from a type of fungus called Fusarium venenatum. This mycoprotein, on its own, is entirely vegan. However, for many years, a significant portion of Quorn's product line has used rehydrated free-range egg white as a binding agent to achieve a desired texture and consistency. Vegans, by definition, avoid all animal products and by-products, including eggs. Therefore, any Quorn product containing egg white is suitable for vegetarians but not for vegans. This is the central reason for the confusion and the distinction between the company's vegetarian and vegan offerings.

The Mycoprotein Production Process

Understanding how Quorn is made sheds light on its ingredient variations. The process begins with the fermentation of the Fusarium venenatum fungus in large vats. This process is similar to how yeast is fermented to produce beer or yogurt. The resulting filamentous fungal mycelium is then harvested, treated with heat to reduce ribonucleic acid content, and subsequently mixed with other ingredients before being shaped and cooked. For its vegetarian products, Quorn adds egg white at this stage to bind the mycoprotein fibers together. For its vegan range, which was introduced later in response to growing demand, Quorn substitutes the egg white with alternative plant-based binders such as potato protein. This step is crucial for separating the product lines and is why a consumer must check the label carefully.

Quorn's Vegan Product Line

Recognizing the expanding vegan market, Quorn has made a conscious effort to increase its vegan offerings. This includes creating explicitly labeled vegan versions of popular items. To make these products vegan-friendly, the egg white binder is replaced with a plant-based alternative. Examples of readily available vegan Quorn products include:

  • Quorn Vegan Pieces
  • Quorn Vegan Nuggets
  • Quorn Vegan Hot & Spicy Burgers
  • Quorn Vegan Fishless Fillets
  • Quorn Vegan Smoky Ham Free Slices

This dedicated vegan line has received accreditation from the Vegan Society, and their logo is featured prominently on the packaging to help consumers make an informed choice.

Comparing Vegetarian and Vegan Quorn Ingredients

To illustrate the key differences, the following table compares the typical ingredients used in vegetarian and vegan Quorn products. This highlights why strict vegans must avoid certain items from the brand's general range.

Feature Vegetarian Quorn Products Vegan Quorn Products
Core Protein Mycoprotein (fungi-derived) Mycoprotein (fungi-derived)
Primary Binder Rehydrated Free Range Egg White Potato protein or Pea protein
Milk/Dairy Some products may contain milk proteins Excludes all milk and dairy derivatives
Certification Vegetarian Society approved Vegan Society approved
Dietary Suitability Lacto-ovo vegetarians Vegans, lacto-ovo vegetarians

How to Identify Vegan Quorn

The easiest and most reliable way to ensure a Quorn product is vegan is to read the packaging. Quorn clearly labels its vegan items with the word “vegan” in the product name (e.g., “Quorn Vegan Pieces”) and often includes the Vegan Society's logo. Without this explicit vegan labeling, it is safest to assume the product contains animal-derived ingredients, such as egg whites or milk proteins. The front of the packaging will always specify if the product is vegan, so always double-check before purchasing.

Other Considerations for Ethical Diets

While the addition of eggs is the main nutritional reason Quorn is not always vegan, some ethical vegans have also raised concerns about the company's past practices. Early in the product's development, mycoprotein's safety was tested on animals. However, Quorn states that no animal testing has occurred since 1995, and the company is committed to not conducting any in the future. Furthermore, for those concerned with animal welfare, Quorn switched to using only free-range eggs in its vegetarian products in 2004, a move that earned it the Vegetarian Society's seal of approval. These issues are part of a broader conversation about food ethics and processing for those following a vegan lifestyle.

Conclusion

In summary, the key distinction for those asking 'why is Quorn not vegan?' is the use of egg white as a binding agent in many of the company's vegetarian products. While the core ingredient, mycoprotein, is fungi-derived and naturally vegan, the additives are what determine the final product's status. For individuals following a strict vegan diet, it is essential to look for the specific Quorn products explicitly labeled as vegan, as these use plant-based binders instead. Being a careful label reader is the best way to navigate the Quorn product range and ensure it aligns with a vegan lifestyle. The existence of a dedicated vegan line shows the company's adaptation to evolving dietary demands, offering a viable, high-protein alternative for everyone.

Frequently Asked Questions

Mycoprotein is a protein-rich, fibrous substance derived from a naturally occurring fungus called Fusarium venenatum, which is grown through fermentation.

Yes, Quorn has a dedicated line of vegan-friendly products that are clearly labeled. These products use plant-based binders, unlike their vegetarian counterparts.

Egg white is used as a binding agent in Quorn's vegetarian products to help create the desired meaty texture and hold the product's shape.

Always check the product packaging. Vegan Quorn products are explicitly labeled 'vegan' and often feature a Vegan Society logo. If it doesn't say 'vegan', it's likely not.

Some vegetarian Quorn products may also contain other animal derivatives, such as milk proteins, so reading the full ingredient list is important.

Technically, no. The fungus that produces mycoprotein belongs to its own kingdom, separate from both plants and animals. However, it is a meat-free, non-animal protein source.

The initial safety testing of mycoprotein involved animal trials in the past. However, Quorn states that it has not conducted animal testing since 1995 and is committed to not doing so in the future.
