Mustard Allergy | One of the UK 14 Major Food Allergens

Mustard is one of the 14 major food allergens in the UK which must be labelled and highlighted if included in food or drink products. Mustard is often derived from mustard powder and mustard seeds. Mustard sauce comes in a variety of types, such as Dijon mustard, English mustard, or wholegrain mustard. Consumers can have severe reactions ranging from wheezing, nausea, hives, and anaphylaxis in severe cases if they consume an ingredient they are allergic to or intolerant to. Food companies must state the 14 major allergens, if present in their product, in bold, contrasting colours, or must be highlighted.

While not an exhaustive list, some of the most common foods containing mustard are:

  • Bread
  • Salad dressing
  • Barbeque Sauce
  • Soups and sauces
  • Pickles
  • Mayonnaise
  • Processed and deli meats

It may not be recognisable in the smell or taste of the food item, or be visually obvious. One should always check the label before consuming the product.


14 Main Food Allergens - Mustard

mustard powder

The mustard plant, which belongs to the Brassica family, produces mustard seeds which can be white, yellow, black, or brown. Brown and black seeds are spicier than white and yellow seeds and are added to ingredients such as vinegar, sugar, and salt. Mustard can be labelled mild or hot depending on the seed combinations used to achieve heat strength, but this is not a requirement when labelling food products. It is critical for individuals to closely read the label of their food item in the event that mustard is in it.

Mustard seeds can be processed into flour or powder, and utilised in various cooking methods. While cooking with mustard, chefs and cooks can use whole seeds in a range of methods within food products such as marinating, roasting, or adding to pickled foods. Table mustard can be made by combining whole, powdered, cracked, or bruised mustard seeds. Mustard can also be used to thicken sauces and add flavour.

What is Mustard?

The classic jars of prepared mustard in supermarkets are made from ground mustard seeds (Colman’s, for example blends both white and brown mustard seeds to form a mustard flour), mixed with vinegar, water, or other liquids. The Colman’s popular recipe includes water, sugar, salt, wheat flour, turmeric (for the signature colour), citric acid, and stabiliser (xanthan gum).
