Finding sulphites on the ingredients list

You’ll find sulphites under various names on the ingredients label. Despite the fact that the presence of sulphite must be stated (like all top allergens) it’s always best to check the ingredients list, especially if you are outside Canada.

Here is the list of names to check:

  • Calcium sulphite (E226)
  • Calcium bisulphite (E227)
  • Potassium bisulphite (E228)
  • Potassium metabisulphite (E224)
  • Potassium sulphite (E225)
  • Sodium bisulphite (E222)
  • Sodium dithionite
  • Sodium metabisulphite (E223)
  • Disodium sulphite (E221)
  • Sulphite / Sulphite
  • Sulfur dioxide (E220)
  • Sulphiting agents
  • Sulphurous acid

NB: names beginning with “E” are European names for sulphites.

Top Sulphite-Containing Foods

You’ll find sulphites principally in processed foods, but they are also naturally present in grapes (and therefore wine). Here is a list, non-exhaustive, of the principal foods that can contain sulphites*:

  • Cereal bars (especially those containing dried fruit)
  • Deli meats
  • Dried fruits (organic products don’t usually contain any sulphites)
  • Frozen fish and seafood
  • Fruit juice
  • Grapes
  • Olives, gherkins and other condiments
  • Vinegar
  • Wine and other alcohol products

* You will need to check the ingredient labels of processed foods (mention “contains” or “may contain” sulphites, or other synonyms). If you’re unsure, contact the manufacturer or avoid consuming the product. It’s also worth checking among different brands for a particular product, some add sulphites while others don’t.

The Solution!

We’ve recently started offering the possibility to add the exclusion “sulphites” to your profile. This way, you can search for recipes that are compatible with your profile, which means without sulphites, as well as getting meal plans adapted to your sulphite intolerance.
