Emulsifiers are chemical additives used in food processing to maintain a uniform dispersion of ingredients, such as oil and water, and to improve the texture and consistency of various products.12

Common foods that contain emulsifiers include:

  • Dairy and Frozen Desserts: Ice cream uses emulsifiers to prevent the formation of large ice crystals and maintain a smooth texture.12
  • Spreads and Fats: Margarine and shortening rely on these additives to keep their components suspended.1
  • Condiments: Mayonnaise and various salad dressings utilize emulsifiers to stabilize oil-in-water mixtures.12
  • Bakery Products: Emulsifiers are added to improve the volume, uniformity, and fineness of baked goods.12

These additives are often derived from natural sources, such as algae (e.g., carrageenan) or egg yolk, which contains lecithins. By preventing ingredient separation, they also help extend the shelf life of these food items.12
