glukonolactone

Glucolactone, also known as glucono delta-lactone (GDL), is a naturally occurring substance derived from glucose. It is a cyclic ester of gluconic acid and is commonly found in fruits, honey, and wine. In its solid form, GDL appears as a white crystalline powder.

When dissolved in water, GDL slowly hydrolyzes to form gluconic acid. This gradual release of acidity makes it a versatile ingredient in various applications. Its primary use in the food industry is as a leavening agent, a coagulant, and an acidulant. As a leavening agent, it reacts with baking soda to produce carbon dioxide, causing baked goods to rise. It is also used in dairy products, such as tofu and cheese, to control texture and coagulation. In processed meats, GDL can enhance color and shelf life.

Beyond food, GDL has applications in cosmetics and personal care products. Its mild acidic properties contribute to exfoliation and skin conditioning. It is often found in skincare formulations aimed at improving skin texture and reducing the appearance of fine lines. The slow release of acidity allows for a gentler effect compared to stronger acids. GDL is also utilized in some industrial processes, though its use in food and cosmetics is more prevalent. It is generally recognized as safe (GRAS) by regulatory bodies for its intended uses.
