What it is

Mustard flour is made by grinding dried mustard seeds. It can come from yellow (white), brown, or black mustard seeds, which are part of the mustard plant.

Why it's used

It is used to add a pungent, spicy flavor to foods. Mustard flour also acts as a natural emulsifier, helping to bind oil and water in products like mayonnaise and salad dressings, and can contribute to thickening.

Health notes

Mustard flour is generally recognized as safe (GRAS) by the FDA when used in food. While it is a common food ingredient, specific evaluations of mustard flour as a food additive by bodies like JECFA or EFSA are not typically conducted, as it is considered a food itself rather than an isolated additive. There are no notable health controversies associated with its consumption, beyond allergic reactions in sensitive individuals.

Allergen info

Mustard is not one of the nine major food allergens identified by the FDA. However, some individuals can have allergic reactions to mustard.
