Glucono delta-lactone (abbreviation GDL) or gluconolactone, an inner ester of gluconic acid, is a naturally occurring ingredient commonly used as a coagulant in tofu making, a leavening acid in bakery, a mild acidulant in cheese and meat products, and a sequestrant in some food applications. The European food additive number for it is E575. It is kosher, halal, vegan and GMO free.

In aqueous solution, GDL rapidly dissolves and the lactone ring opens up and slowly hydrolyzes to gluconic acid[7], thus producing mild acidification. And there is an equilibrium between D-gluconic acid (55% – 66%) and the delta and gamma lactones.
