E575 Glucono δ-lactone or Glucono delta-lactone

What is Glucono δ-lactone (GDL)?

E575, known as glucono δ-lactone (GDL), is a food additive that acts as an acidity regulator and is derived from gluconic acid. It appears as a white, crystalline powder and is commonly used in the production of tofu, dairy products, and various baked goods. GDL is valued for its ability to impart a mild acidic flavor while also enhancing the texture and shelf-life of food products.

Why do I have an intolerance?

Intolerance to glucono δ-lactone can stem from individual sensitivities to food additives or specific ingredients used in the manufacturing process. Some individuals may experience digestive issues, such as bloating or cramping, when consuming products containing GDL, particularly those who are sensitive to acidic foods or additives. Additionally, those with fructose intolerance may also react to GDL, as it can interfere with the absorption of certain sugars.

What can I do about it?

To manage intolerance to E575, it is advisable to avoid processed foods that list glucono δ-lactone as an ingredient. Cooking from scratch using whole ingredients can help ensure that you do not inadvertently consume this additive. You may also explore natural alternatives for acidity regulation, such as lemon juice or vinegar, which can provide a similar tartness in recipes without the adverse effects associated with GDL.
