Purpose and Function

Calcium silicate is primarily used as an anticaking agent in food applications:

  • Anticaking Agent: It helps prevent clumping in powdered foods, ensuring even distribution and flowability.
  • Stabilizer: Calcium silicate can help stabilize emulsions in food products, improving texture.
  • Improves Shelf Life: By preventing clumping and stabilizing formulations, it helps enhance shelf life and prevent spoilage.

Potential Risks and Side Effects

Calcium silicate is generally regarded as safe for consumption. However, some considerations include:

  • Gastrointestinal Issues: Excessive intake may lead to gastrointestinal discomfort, including bloating or gas.
  • Allergic Reactions: Rarely, individuals may experience allergic reactions to, particularly those with sensitivities to silicate compounds.
  • Contaminants: Sourcing from reputable suppliers is essential to minimize the risk of contaminants in food formulations.
