What is a Glucono-δ-lactone?

Glucono-δ-lactone is an organic compound with the chemical formula C6H10O6. It is a cyclic ester derived from the oxidation of glucose. Glucono-δ-lactone is typically found as a white crystalline or powdered substance and is widely used in the food and pharmaceutical industries, primarily as an acidulant, antioxidant, and coagulant. When dissolved in water, glucono-δ-lactone slowly converts to gluconic acid. This property is useful in food applications, particularly for controlling pH levels and facilitating stable oxidation reactions during fermentation. It is commonly used as a coagulant in the production of products like cheese and tofu.

Additionally, glucono-δ-lactone is found in cosmetics, where it enhances skin hydration and softness. It is commonly included in moisturizing creams, lotions, and masks for its beneficial effects on skin care.
