What it is

Glucono-delta-lactone (GDL) is a naturally occurring cyclic ester of gluconic acid. It is made by dehydrating gluconic acid, which is produced by fermenting glucose, often from corn.

Why it's used

GDL acts as a slow-release acidulant, meaning it gradually lowers the pH of foods as it dissolves in water. This makes it useful in products like cheese, baked goods, and cured meats, where a gradual increase in acidity is desired for texture, flavor, or preservation.

Health notes

GDL is generally recognized as safe (GRAS) by the FDA for use in food. It is metabolized by the body into glucose. International bodies like JECFA have evaluated GDL, and EFSA has also assessed its safety. No significant health concerns are associated with its typical use in foods.

Allergen info

GDL is not derived from any of the nine FDA major allergens and does not contain gluten.
