By definition, anti-caking agents<\/a> are anhydrous compounds that are added in small amounts to dry foods to prevent the particles caking together and ensure the product remains dry and free-flowing.<\/p>\n

Without anti-caking agents, dry soup, cake and biscuit mixes would be clumped and chunky, cappuccino and hot chocolate vending machines would not function properly, and premixes for manufacturing would not be as easy to use. These agents are often found in milk<\/a> and cream powders<\/a>, flour-based mixes, baking powder<\/a>, table salt, cocoa, and mixed coffee beverages, to name a few. In manufacturing, the addition of anti-caking agents helps prevent bridging during the packaging process, which can reduce production rates.<\/p>\n

Anti-caking agents function by absorption of excess moisture or by coating particles to make them more water repellant. In addition to food, anti-caking agents aid other industries,\u00a0such as those producing cosmetics and detergents.<\/p>\n

In the EU, most anti-caking agents have E-numbers in the 500 range, but some have multiple functions and fall into further categories.<\/p>\n

Some of the multi-functional compounds include:
\nMannitol (E421) \u2013 also functions as a humectant, sweetener, and texturizer.
\nAlpha Cellulose (E460b) and Microcrystalline Cellulose (E460a) \u2013 also functions as a binder, stabilizer, and bulking agent.<\/p>\n

Alternatives to anti-caking agent additives seen in some markets include rice hull powder and corn starch<\/a>.<\/p>\n

Recent News<\/h3>\n

In January, 2015, the EFSA deemed the use of sodium tartrate mixtures with iron chloride (Fe mTA)\u00a0acceptable for use<\/a>\u00a0as an anti-caking agent in salt, at a maximum use level of 106 mg\/kg salt.<\/p>\n

In August, 2015, the\u00a0Grocery Manufacturers Association<\/a>\u00a0petitioned the FDA for limited use of partially hydrogenated oils. One of the uses included was as an anti-caking additive.<\/p>\n

In September 2015, the\u00a0EFSA revised their opinion<\/a>\u00a0on Friedland mineral clay for feed use. They will now allow it as an anti-caking agent and binder at a level of 2% in all animal feeds.<\/p>\n
