What it is

Monopotassium tartrate is a salt of tartaric acid, a naturally occurring organic acid found in fruits like grapes. It is typically produced by neutralizing tartaric acid with a potassium source.

Why it's used

It is commonly used in baking as a leavening agent, often in combination with baking soda, to help doughs and batters rise. It can also act as an acidity regulator and stabilizer in various food products, including desserts and beverages.

Health notes

Monopotassium tartrate is generally recognized as safe (GRAS) by the FDA for use in food. International bodies like JECFA have evaluated tartaric acid and its salts, and EFSA has also assessed their safety. At typical consumption levels found in food, it is not associated with adverse health effects.

Allergen info

Monopotassium tartrate is not derived from any of the FDA's nine major allergens. It does not contain gluten.
