Anti-foaming agent

An antifoaming agent is a food ingredient intended to curb effusion or effervescence in preparation or serving. Antifoaming agents are included in a variety of foods such as Diet Coke, Sprite, and Chicken McNuggets in the form of dimethylpolysiloxane . Antifoaming agents are also used medicinally to relieve bloating , because they cause small bubbles to coalesce into large bubbles, which are passed more easily. A familiar example is the drug Simethicone, which is the active ingredient in drugs such as Gas-X.
