Why do they put aluminum salt in salad dressing?

Aluminum salts, such as aluminum potassium sulfate, are sometimes added to salad dressings as emulsifiers or stabilizers. They help to blend oil and water-based ingredients, ensuring a smooth and consistent texture. Additionally, they can enhance the shelf life of the product by preventing separation and maintaining quality over time. However, their use is subject to regulations and consumer preferences, with some opting for aluminum-free alternatives.
