Glucon Delta Lactone

Glucono delta-lactone (GDL) is a naturally occurring compound that is a cyclic ester of gluconic acid. It is produced by the oxidation of glucose, often using a fermentation process. GDL is a white crystalline powder that is soluble in water.

GDL acts as a leavening agent and acidulant in baked goods, producing a slow, steady release of carbon dioxide when mixed with baking soda. It is also used to acidify dairy products like cheese and yogurt, and as a curing agent in processed meats. It is found in cakes, cupcakes, and snack cakes.

In the United States, GDL is Generally Recognized As Safe (GRAS) by the FDA for use as a food additive. It is metabolized by the body as a carbohydrate. International bodies like JECFA and EFSA have evaluated GDL and found it to be safe for consumption. There are no widespread health controversies associated with its use at typical dietary levels.
