Gluconolactone, also known as gluconolactone or E575, is a natural substance found in honey, fruit and wine. It is a white crystalline powder with very mild or no taste and odor. It is a commonly used food additive that is used for its ability to regulate acidity and for its preservative properties. Gluconolactone is an organic substance that undergoes metabolic processes in the body and is eliminated as water and carbon dioxide.
There are a number of foods and beverages to which gluconolactone is added. It is often added to food products as an acidity regulator, especially in low pH foods such as lemon juice-based drinks, ice cream or baked goods. Due to its preservative properties, it is also used in fermented dairy products such as yoghurt. Gluconolactone is also included in some cosmetic products due to its moisturizing and antioxidant properties. In pharmaceuticals, it serves as an ingredient in increasingly popular products to support gut and digestive health.
