What it is

Glucono-delta-lactone (GDL) is a naturally occurring carbohydrate derived from glucose. It is produced commercially by the oxidation of glucose to gluconic acid, followed by purification and crystallization.

Why it's used

GDL functions as an acidulant, creating a slow-release acidity in foods. It is often used in cheesemaking to help coagulate milk proteins, in baked goods as a leavening agent in combination with baking soda, and in processed meats to lower pH. It can also be found in salad dressings and sauces.

Health notes

GDL is generally recognized as safe (GRAS) by the FDA for use in food. It is metabolized by the body like other carbohydrates. International bodies like JECFA have evaluated GDL and established acceptable daily intake levels. No significant health controversies are associated with its typical use in food.

Allergen info

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