Gluconolactone

Gluconolactone (CAS 90-80-2), also known as GDL and E575, is a naturally derived lactone used commercially as a slow-release acidulant and mild humectant.

Where is Gluconolactone used?

• Food manufacturing: acidifies tofu and processed meats
• Dairy analogues: triggers protein coagulation without heat or starter cultures
• Bakery: leavening acid with sodium bicarbonate
• Personal care: mild exfoliant and pH adjuster in serums and toners
• In cured and fermented meats it lowers pH rapidly during processing.

Good to know: Unlike fast-acting acids, it hydrolyzes gradually in aqueous systems, giving formulators precise control over pH reduction without sharp sensory impact.
