E552 – Calcium silicate
Anticaking agentDescription
Fine, white or off-white powder
Notes
Calcium silicate is a fine white powder made by combining calcium compounds (like limestone) with silica (essentially sand or quartz). The manufacturing process involves heating these materials together at high temperatures, then grinding the result into an extremely fine, almost talc-like powder. This creates a substance that has unique properties for keeping other powdered ingredients flowing freely. In food production, calcium silicate works as an anticaking agent, which means it prevents powdered foods from clumping together and forming hard lumps. You'll commonly find it in table salt, powdered spices, baking powder, and powdered drink mixes. It also serves as a release agent in food manufacturing, helping to prevent ingredients from sticking to processing equipment during production. This additive is entirely synthetic, created through industrial processes rather than extracted from natural sources. It's suitable for vegetarian and vegan diets, and there are no specific religious dietary restrictions associated with it. Calcium silicate is considered safe for consumption in the small amounts typically used in food products, and it's been approved by food safety authorities worldwide for use in various food categories.
