Glucono delta-lactone (GDL), also known as gluconolactone, is a food additive with the

E number E575 used as asequestrant, an acidifier, or a curing, pickling, or leavening agent.

It is a lactone (cyclic ester) of D-gluconic acid. Pure GDL is a white odorless crystalline powder.

GDL is commonly found in honey, fruit juices, personal lubricants, and wine . GDL is neutral,

but hydrolyses in water to gluconic acid which is acidic, adding 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

yields roughly the same amount of metabolicenergy as one gram of sugar.
