General description

D-(+)-Gluconic acid δ-lactone (GDL) is soluble in water and hydrolyzes into gluconic acid spontaneously and homogeneously lowers the pH. Quinoprotein glucose dehydrogenase converts D-glucose to GDL which gradually lowers the pH and transcriptionally controls the prodigiosin production. GDL is commonly used in the food industry to cause gelation of sodium caseinate by acidification. GDL helps to overcome the difficulties and variations of using starter bacterial cultures.

Application

D-(+)-Gluconic acid δ-lactone has been used in the preparation of cold set gels, and hydrogels.

Biochem/physiol Actions

Glucono-d-lactone increased the doubling time and activated enzymes involved in the oxidative pentose phosphate pathway of Saccharomyces cerevisiae.
