What the sources tell us
The Gluten Intolerance Group says mayonnaise is typically made of eggs and oil, and that most popular brands do not add gluten-containing flavorings. Its broader answer on condiments is that they are not necessarily gluten-free, so it advises checking the labels of anything you add to a sandwich.[6]
The group adds that condiments are regulated by the FDA, so even a mayonnaise that is not labeled gluten-free must say on its label whether wheat-based ingredients have been added.[6]
In its guide to holiday foods, the group says the condiments used for deviled eggs, including mayonnaise, mustard, vinegar and paprika, are all typically gluten-free, while still asking you to make sure the ones you use are.[7]
Shared jars are another concern. The Celiac Disease Foundation lists mayonnaise among condiments that may become contaminated when utensils used on gluten-containing food are double-dipped. The Gluten Intolerance Group says a spreadable condiment such as mayonnaise becomes contaminated with crumbs when someone dips into it a second time with the knife used for spreading.[4][5]
To prevent that kind of cross-contact, the group suggests using condiments in squeeze containers when you can.[5]
The GFCO list includes Mayonnaise 12 oz from Kewpie, Mayonnaise 16 oz from O Organics and Canola Mayonnaise 16 oz from Spectrum Essentials. GFCO notes that a product found on its list is not certified if its packaging does not carry the certification mark.[2][3][1]
