Glucono Delta Lactone

Glucono delta lactone, often abbreviated to GDL, is a naturally occurring food ingredient. It is known as an acidity regulator. It is used in the production of foodstuffs to lower the pH, or acidity, of the product.

Glucono delta lactone functions as a curing, pickling and leavening agent. It also has the ability to control pH by increasing the acidity of the product. From a nutritional standpoint, GDL is completely metabolized in the body like any other carbohydrate, providing 4 kcal/g.

Characteristics

• PH-Neutral, but hydrolyses in water to gluconic acid which is acidic,
• Tangy taste to foods
• Has roughly a third of the sourness of citric acid
