Acidity Regulator: Glucono-delta-lactone

Glucono-delta-lactone (GDL) is a natural compound that is a solid form of gluconic acid. It is made from glucose, which can come from corn or other plant sources, through a fermentation process. GDL slowly breaks down into gluconic acid when exposed to water.

GDL is used as an acidity regulator, a leavening agent, and a curing agent. It provides a gradual release of acidity, which is useful in baked goods, cheeses, and processed meats. It is often found in products like salad dressings, tofu, and spice mixes.

GDL is generally recognized as safe (GRAS) by the FDA for use in food. It is a natural breakdown product of glucose and is metabolized by the body. International bodies like JECFA have evaluated GDL, and it is permitted for use in many countries. There are no widespread health controversies associated with its use at typical dietary levels.
