Glucono delta-lactone
Glucono delta-lactone (GDL) is a naturally occurring food additive used as a sequestrant , an acidifier, or a curing, pickling, or leavening agent. It is a cyclic ester of D-gluconic acid with chemical formula 106 and CAS number 90-80-2. Pure GDL is a white odorless crystalline powder.
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.
