An Antifoaming Agent Added

Antifoaming agents are substances added to food to prevent or reduce foaming during processing. They are typically made from a base of oil or fat, such as vegetable oil or animal fat, combined with other ingredients like silicon dioxide or emulsifiers. These agents work by lowering the surface tension of liquids, which prevents bubbles from forming or causes them to break quickly.

Manufacturers add antifoaming agents to foods where foaming can be a problem during cooking or processing, such as in frying oils, baked goods, and processed foods. They help ensure consistent product texture and appearance, and prevent overflow during manufacturing. They are commonly found in vegetable and cooking oils, prepared sandwiches, and baked items like biscuits.

In the US, antifoaming agents are generally recognized as safe (GRAS) by the FDA when used according to good manufacturing practices. Regulatory bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) have evaluated many antifoaming agents, often establishing acceptable daily intakes. Evidence generally shows these substances are not absorbed by the body and pass through undigested at typical consumption levels.
