description Product Description
D-(-)-Gluconic acid δ-lactone is widely used in the food industry as a mild acidulant. It is particularly valued in baking powders and leavening agents because it slowly hydrolyzes to gluconic acid, providing a controlled release of acidity. This property ensures consistent leavening and texture in baked goods. It is also employed in dairy products, such as cheese and yogurt, to adjust acidity and improve texture. In meat processing, it acts as a curing accelerator and enhances the color and shelf life of cured meats. Additionally, it is used in cosmetics and personal care products for its mild exfoliating and pH-adjusting properties. In the pharmaceutical industry, it serves as an intermediate in drug synthesis and as an additive in certain formulations. Its versatility and safety make it a popular choice across various industries.
