Gluconolactone
Glucono-delta-lactone (GDL), also known as gluconolactone, is an organic compound with the formula (HOCH)3(HOCH2CH)CO2. As a colorless solid, it is an oxidized derivative of glucose. GDL is typically produced by the aerobic oxidation of glucose in the presence of the enzyme glucose oxidase.

2.1 Effects in Food
The use in food
Used as a food additive (E-number E575) as a sequestrant, acidifier, or curing, pickling, or leavening agent.
GDL is a lactone of D-gluconic acid, and pure GDL is a white odorless crystalline powder.
Hydrolyzes in water to gluconic acid, giving a tangy taste to foods, though it is about a third as sour as citric acid.
Source
GDL is produced through the aerobic oxidation of glucose in the presence of glucose oxidase.
The production of GDL co-generates hydrogen peroxide.
