Calcium silicate (CaSiO₃) is a compound composed of calcium, silicon, and oxygen. Its chemical formula is CaSiO₃, and it is typically found in the form of a white powder. In the food industry, it is used as an anti-caking agent to prevent clumping in dry foods and spices, improving flowability. Additionally, it is widely used in the construction sector as an insulation material and in fire-resistant products.
Calcium silicate is also used in some food products for its moisture-absorbing properties. As a food additive, it is known under the code E552 and is generally considered safe.
