E900A – Polydimethylsiloxane
AntifoamDescription
Synthetic silicone polymer
Notes
Simethicone is a synthetic compound made from silicone, the same type of material used in flexible kitchen utensils and sealants, but specifically designed for food use. It's created by combining silicon (a common element found in sand and quartz) with oxygen and carbon in a laboratory process that produces a smooth, slippery polymer - think of it as tiny, food-safe silicone particles. This additive works as an antifoaming agent, which means its job is to prevent or reduce foam and bubbles during food processing. You'll commonly find simethicone in processed foods like cooking oils, fruit juices, soups, and dairy products where excessive foaming during manufacturing could create problems with texture, appearance, or processing efficiency. Simethicone is entirely synthetic, meaning it's made in laboratories rather than extracted from natural sources. It's suitable for vegetarian and vegan diets since it contains no animal products, and it doesn't conflict with religious dietary laws. The compound is considered very safe because it doesn't break down in the digestive system - it simply passes through the body unchanged, which is why it's also used in over-the-counter medications for gas relief.
