Product Features

Glucono delta lactone is a carbohydrate that contains a lactone formation. In an aqueous solution there is an equilibrium between gluconic acid and the delta and gamma lactones.

Applications & Uses

Applications

GDL is commonly found in honey, fruit juices, and wine. Being acidic, it adds a tangy taste to foods, though it has roughly a third of the sourness of citric acid. It is metabolized to glucose; one gram of GDL is equivalent to one gram of sugar. In processed foods, GDL functions as a curing and pickling agent; leavening agent; pH control agent; and sequestrant.
