Natural Occurrence
GDL is the lactone (cyclic ester) form of gluconic acid. It occurs in small amounts in nature and is produced commercially by purification and crystallization from gluconic acid solutions.
Manufacturing
Produced by fermenting glucose to gluconic acid (using Aspergillus niger or bacteria), then crystallizing the lactone form. GDL forms naturally when gluconic acid is concentrated and cooled. The solid crystalline form is stable but slowly hydrolyzes back to gluconic acid in water.
Applications Beyond Food
Exfoliant, pH adjuster, moisturizer (polyhydroxy acid, PHA).
Slow-release acidulant, calcium supplement formulations.
Textile treatment, concrete additives, metal cleaning.
Not typically used.
