Mustard Seed

Mustard seeds are small, round seeds harvested from various mustard plants, primarily Brassica juncea (brown mustard), Sinapis alba (white/yellow mustard), and Brassica nigra (black mustard). These seeds are used whole, crushed, or ground into a powder, and can also be pressed to extract mustard oil.

Manufacturers add mustard seed primarily for its pungent flavor and aroma, which can range from mild to very spicy depending on the type. It also acts as a natural emulsifier and thickener in some preparations. It is a key ingredient in condiments like mustard, ketchup, salad dressings, mayonnaise, and is frequently used in pickling brines.

Mustard seed is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. While considered safe for most people, some individuals may experience allergic reactions, which can range from mild symptoms to severe anaphylaxis. JECFA has evaluated mustard seed oil, and mustard seed as a food ingredient is widely consumed without specific health concerns at typical intake levels.
