Anti-foam Agent

Anti-foam agents, also called antifoaming agents or defoamers, are substances that prevent or reduce foaming. They are typically made from silicones, oils, or fats, and are added to foods to control foam that can form during processing, such as during cooking or mixing.

Manufacturers add anti-foam agents to prevent excessive foam from interfering with food production or packaging. They are commonly found in baked goods like breads and buns, as well as in frozen appetizers and doughs, where foaming can occur during mixing or baking.

In the U.S., anti-foam agents are generally recognized as safe (GRAS) by the FDA when used as intended. International bodies like JECFA have also evaluated these substances. At the levels typically used in food, they are not expected to cause harm. There are no widespread controversies regarding their use in food.
