E563 – Sepiolitic clay
Description
Hydrated magnesium silicate; a naturally occurring, fibrous clay mineral with a high surface area and absorbent properties
Notes
Sepiolite is a naturally occurring clay mineral that forms when magnesium-rich water interacts with silica (the same material that makes up sand and quartz) over long periods of geological time. It's mined from deposits around the world and has a unique fibrous structure that makes it excellent at absorbing moisture and other substances. The mineral is processed by grinding and purifying the raw clay to create a fine powder suitable for food use. In the food industry, sepiolite works as an anticaking agent, preventing powdered foods from forming lumps by absorbing excess moisture that would otherwise cause clumping. It also serves as a carrier, helping to evenly distribute flavors, colors, or other additives throughout food products. You might encounter it in powdered spices, drink mixes, and various processed foods where maintaining a free-flowing powder is important. As a naturally occurring mineral, sepiolite is considered a natural additive rather than synthetic. It's suitable for all dietary preferences including vegan and vegetarian diets, and doesn't conflict with religious dietary laws. The food-grade version is carefully processed to ensure purity and safety, and regulatory authorities have approved its use in food applications at specified levels.
