Mustard powder is made from ground mustard seeds and is described here in its dry form, using data for two brands. It provides fat, protein and carbohydrate, as well as minerals. Per 100g, it contains 29g of fat, 29g of protein, 330mg of calcium and 0.01g of salt.

Protein contributes to the maintenance and repair of body tissues, while calcium is needed for bones and teeth. Mustard powder is generally used in small amounts as a seasoning, so its contribution depends on the amount used. Added ingredients in prepared mustard or sauces can change the salt and energy content. Full nutrient figures are in the tables below.
