DESCRIPTION

General description

D-(+)-Gluconic acid δ-lactone (GDL) is soluble in water and hydrolyzes into gluconic acid spontaneously and homogeneously lowers the pH.[1] Quinoprotein glucose dehydrogenase converts D-glucose to GDL which gradually lowers the pH and transcriptionally controls the prodigiosin production.[2] GDL is commonly used in the food industry to cause gelation of sodium caseinate by acidification.[3][4] GDL helps to overcome the difficulties and variations of using starter bacterial cultures.[3]

Application

D-(+)-Gluconic acid δ-lactone has been used in the preparation of cold set gels,[1] and hydrogels.[5][6]

Packaging

Biochem/physiol Actions
