food products : glucono delta-lactone

Product Information

Glucono Delta-Lactone is a lactone (cyclic ester) of D-gluconic acid. It is prepared by direct crystallization from the aqueous solution of gluconic acid. Its appearance is a fine, white, practically odorless, crystalline powder. It is freely soluble in water and is sparingly soluble in alcohol. The product has fresh preservation and antiseptic actions, functions as; pH control agent, leavening agent and sequestrant. It hydrolyzes to gluconic acid in water The rate of hydrolysis of GDL is increased by heat and high pH

As a food additive, it has E number E575.

Structural unit and Molecular structure

Compared to other food acids, glucono delta-lactone has two differentiating properties: Due to its slow hydrolysis to gluconic acid (which takes place gradually over the forty to sixty minutes after dissolution), it provides a gradual, progressive and continuous decrease of pH to equilibrium. Accordingly, it is used as a slow release acidulant. During its hydrolysis, its initial sweet taste becomes only slightly acidic, making the final flavor of an aqueous solution much less tart than that of other acidulants 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.
