What it is

Extra heavy mayonnaise is a type of mayonnaise with a higher oil content than standard mayonnaise, typically around 70% or more. It is an emulsion made primarily from oil, egg yolk, and an acid, such as vinegar or lemon juice. The higher oil content gives it a richer, thicker texture.

Why it's used

Manufacturers use extra heavy mayonnaise as an emulsifier and a source of fat and flavor. Its rich texture makes it ideal for creamy dressings, dips, and as a binder in salads like chicken or tuna salad. It is often found in deli salads and prepared sandwiches.

Health notes

In the US, mayonnaise and its ingredients are generally recognized as safe (GRAS) by the FDA. Extra heavy mayonnaise is primarily composed of oil and egg, which are sources of fat and protein. JECFA has evaluated mayonnaise and found no safety concerns at typical consumption levels. Evidence does not suggest adverse health effects from consuming mayonnaise in moderation as part of a balanced diet.

Allergen info

Extra heavy mayonnaise contains egg, which is one of the 9 FDA major allergens. It does not typically contain gluten.
