what are emulsifiers in food

Emulsifiers are food additives that help mix two substances that typically separate when they are combined, such as oil and water. They are chemically designed to have one end that is compatible with oil and another end that is compatible with water, so they can link with both. Emulsifiers can be naturally derived or synthetic, and they are used extensively in food manufacturing to enhance the appearance, texture, and shelf-life of many processed and packaged foods. Some common examples of foods that contain emulsifiers include mayonnaise, margarine, meats, ice cream, salad dressings, chocolate, peanut butter, shelf-stable frostings, cookies, crackers, creamy sauces, breads, and baked products. Emulsifiers also reduce food stickiness and help foods maintain a smooth texture and flavor.
