Anticaking agent(Redirected from Anti-caking agent)
An anticaking agent is an additive placed in powdered or granulated materials, such as table salt or confectionaries to prevent the formation of lumps (caking) and for easing packaging, transport, and consumption.
An anticaking agent in salt is denoted in the ingredients, for example, as "anti-caking agent (554)", which is sodium aluminosilicate, a man-made product. This product is present in many commercial table salts as well as dried milk, egg mixes, sugar products, flours and spices. In Europe, sodium ferrocyanide (535) and potassium ferrocyanide (536) are more common anticaking agents in table salt. "Natural" anticaking agents used in more expensive table salt include calcium carbonate and magnesium carbonate.
Some anticaking agents are soluble in water, while others are soluble in alcohols or other organic solvents. They function either by absorbing excess moisture or by coating particles and making them water-repellent. Calcium silicate (CaSiO3), a commonly used anti-caking agent, added to e.g. table salt, absorbs both water and oil.
Some studies suggest that anticaking agents may have a negative effect of food nutrition, such as one study which indicated that most anti-caking agents result in the additional degradation of vitamin C added to food.
List of anticaking agentsEdit
The most widely used anticaking agents include the stearates of calcium and magnesium, silica and various silicates, talc, as well as flour and starch. Ferrocyanides are used for table salt. The following anticaking agents are listed in order by their number in the Codex Alimentarius.
