Emulsifier

An emulsifier is a substance that helps two liquids that normally don't mix, like oil and water, to stay blended together. It works by reducing the surface tension between the liquids, allowing them to form a stable mixture called an emulsion. Emulsifiers can come from natural sources, like plants or animals, or be made synthetically.

Manufacturers add emulsifiers to food products to create smooth textures, prevent separation, and extend shelf life. They are essential in products like mayonnaise, salad dressings, chocolate, ice cream, and baked goods to keep ingredients evenly distributed. Without emulsifiers, these products might separate into layers or have an undesirable texture.

Emulsifier is a broad category of food ingredients, and the regulatory status and health effects vary for each specific type. In the U.S., individual emulsifiers are regulated by the FDA, often being approved as food additives or recognized as Generally Recognized As Safe (GRAS). The safety of each specific emulsifier is evaluated individually, and many have been assessed by international bodies. Consumers should refer to the specific emulsifier listed on an ingredient label for detailed information.
