Emulsifiers

Emulsifiers are food additives that help mix ingredients that normally don't blend, like oil and water. They work by reducing the surface tension between these liquids, creating a stable mixture. This prevents ingredients from separating over time.

Manufacturers add emulsifiers to improve the texture, consistency, and shelf life of many foods. They are used to create smooth sauces, creamy dressings, and stable baked goods. Common foods include mayonnaise, ice cream, chocolate, and various baked goods like cookies and cakes.

Many individual emulsifiers are approved by the FDA as food additives or are generally recognized as safe (GRAS). Regulatory bodies like JECFA and EFSA have evaluated numerous emulsifiers, often setting acceptable daily intakes for specific compounds. While generally considered safe at typical intake levels, some research suggests that high consumption of certain emulsifiers might affect gut microbiota in animal studies, though human evidence is mixed and more research is needed.
