What it is

Sodium diacetate is a salt made from acetic acid, which is the main component of vinegar. It is produced by reacting acetic acid with sodium bicarbonate or sodium hydroxide. It is often used in food as a preservative and flavoring agent.

Why it's used

Sodium diacetate is used to help preserve foods and add a tangy, salty flavor. It can also help control the acidity of food products. It is commonly found in processed meats like pepperoni and salami, as well as in baked goods and snack foods.

Health notes

In the U.S., sodium diacetate is generally recognized as safe (GRAS) by the FDA for use in food. Regulatory bodies like JECFA and EFSA have evaluated sodium diacetate and have not set a numeric limit for its acceptable daily intake. Some studies suggest high intake of acetate salts may affect blood pressure, but evidence is mixed and more research is needed.

Allergen info

Sodium diacetate is not derived from any of the 9 major allergens recognized by the FDA. It does not contain gluten.
