Glucono Delta Lactose

Glucono delta-lactone (GDL) is a naturally occurring cyclic ester of gluconic acid. It is made by dehydrating gluconic acid, which is produced by the fermentation of glucose, often from corn or other plant sources. In food, it slowly hydrolyzes to gluconic acid when dissolved in water.

GDL acts as a slow-release acidulant, providing a gradual drop in pH. This makes it useful in products where a controlled acidification is needed, such as in processed meats for curing, in cheese making, and as a leavening agent in baked goods. It can also be used to adjust the acidity of sauces and dressings.

In the United States, glucono delta-lactone 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 have evaluated glucono delta-lactone and established acceptable daily intake levels. Evidence does not suggest adverse health effects at typical consumption levels.
