Additives and regulators for an array of food products

If you need texturising agents, anti-caking agents, raising agents, anti-stick coatings, acid regulators, thickeners or bulking agents, we have a selective range of controlled food-additive calcium carbonates and talcs* for a wide range of foodstuffs. 

Calcium carbonate

  • Acidity regulation: calcium carbonate can be used to regulate the acidity or alkalinity of foods such as fruit juices, pastes and preserves. 
  • Raising agent: calcium carbonates are effective raising agents and pH regulators for baked products. Calcium carbonate leavens baked goods by reacting with acids to produce CO2, which causes your mixture to rise. It is particularly effective in cakes. 
  • Thickener and bulking agent: calcium carbonates are effective bulking agents and thickeners, used to increase viscosity in a wide range of applications such as baked products.


  • Anti-caking and anti-sticking: our talc has hydrophobic, organophilic and platy properties that make it an excellent anticaking or separating agent for sticky food products that tend to clump together. Talc’s smooth and flat lamellae cover each particle, helping it to flow freely. Relatively water repellent, talc particles form a barrier when they envelop the food particles, reducing the evaporation and uptake of moisture within the product mass.
  • Filler and carrier: as a soft, innocuous and organophilic substance, Imerys talc is approved as a filler and carrier in food supplements such as vitamin pills.
  • Surface finishing and texturing agent: naturally soft and platy, our talcs also make effective surfacing finishing and texturing agents in foods such as confectionery, processed cheese, rice, processed meats and seasonings.

Our food additive grades are sustainably sourced from high-quality minerals from our own mines. They are processed at our facilities, according to Good Manufacturing Practices (GMP).
