OTHER FOOD APPLICATIONS Imerys food-grade additives and processing agents for a wide range of food stuffs

Imerys offers a selective range of controlled food-additive calcium carbonates and talcs for use as texturizing agents, anti-caking agents, raising agents, anti-stick coatings, acid regulators, thickeners and bulking agents for a wide range of food stuffs. 

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 the mixture to rise. It is particularly effective in cakes. 

Thickener & bulking agent

Calcium carbonates are effective bulking agents as well as thickeners used to increase viscosity in a wide range of applications such as bakery products.


Anti-caking and anti-sticking

Imerys talc’s hydrophobic, organophilic and platy properties make it an excellent anticaking or separating agent for ‘sticky’ food products which tend to clump together. Talc’s smooth and flat lamellae cover each particle helping it to flow freely. Relatively water repellent, the talc particles form a barrier when they envelop the particle, 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 texturizing agent

Naturally soft and platy, Imerys talcs make effective surfacing finishing and texturizing agents in foods such as confectionery, processed cheese, rice, processed meats and seasonings.
