An Emulsifier

An emulsifier is a substance that helps mix two liquids that normally do not blend, such as oil and water. It works by stabilizing small droplets of one liquid within the other. Emulsifiers can be naturally occurring or synthetically produced.

In food, emulsifiers are added to create smooth, consistent textures and to prevent separation. They are commonly found in products like mayonnaise, salad dressings, chocolate, ice cream, baked goods, and processed meats to improve stability and mouthfeel.

Many emulsifiers commonly used in food are considered Generally Recognized As Safe (GRAS) by the FDA. International bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) evaluate individual emulsifiers for safety, often setting acceptable daily intake levels. Some research has explored the potential effects of certain emulsifiers on gut health, but the evidence is mixed and more studies are needed to understand their impact at typical consumption levels.
