What are anti-caking agents for spices?

In this brief guide, we will answer the query, “What are anti-caking agents for spices?”. We will also discuss why anti-caking agents are used in different ingredients, what they are used in, and if they are natural or manufactured. Moreover, we will also answer if brown sugar contains anti-caking agents and if they are safe for consumption.

What are anti-caking agents for spices?

Anticaking agents are additives used in powdered or granular ingredients such as table salt or confectioneries to avoid lump formation (caking) or aggregation and to improve packing, transport, flowability, and consumption. 

Since moisture causes the majority of product caking, anti-caking agents can absorb moisture or serve as a barrier, repelling water and oil. 

Some of the commonly used anti-caking agents are:

  • Sodium aluminosilicate 
  • Sodium ferrocyanide
  • Potassium ferrocyanide
  • Calcium carbonate
  • Magnesium carbonate
  • Calcium silicate
  • Silicon dioxide
  • Hydrophobic silica
  • Calcium phosphate/tricalcium phosphate (bone ash)

Why are anti-caking agents used in different ingredients?

Anti-caking agents are used in different foods to either absorb the excess moisture or to cover particles with a water repellent coating. Without them, different bakery ingredients like sugar, flour, and baking powder would turn into solid blocks of chalk over time. As time passes, these dry substances slowly absorb humidity from the air. 

Because of the water, the particles might bind together. As the ingredients oxidize and lose their ability to flow when poured, the product quality starts degrading. Anti-caking agents solve this issue by either coating the particles to protect them or absorbing moisture before the powder.

What are anti-caking agents added to?

Anti-caking agents are commonly used in different food ingredients including table salt, spices, milk powder, flour, sugar, grated cheese, baking powder, cake mixes, and many more pantry-friendly items. Other than these food products, they are also used in non-food items like road salt, fertilizers, cosmetics, synthetic detergents, etc.

Anti-caking agents are mostly found in ingredients that are susceptible to clumping, such as sugar, salt, or flour. These common ingredients often crystallize, resulting in solid blocks that do not pour evenly and are difficult to blend. This may restrict their use in baking and cooking. 

Hence, the use of anti-caking agents avoids the formation of these clumps.

Some of the anti-caking agents added to specific ingredients are:

  • Sodium dioxide is used in powdered eggs and even for filtering beer.
  • Calcium silicate is used in table salt and some spices to inhibit the movement of oils and absorb water.
  • Mannitol (a sugar substitute) is used to dust chewing gum and other items to prevent them from sticking together.
  • Cellulose is a frequent additive to parmesan cheese which functions similarly by preventing the cheese from solidifying again.
  • Stearic acid is a common fatty acid that is found in cow’s milk fat and can be used to make edible coatings that may extend shelf life by preventing contact with water and other food components.

Are anti-caking agents natural or manufactured?

There are both natural as well as manufactured anti-caking agents found on the market. Some anticaking agents like bentonite are naturally occurring, while others are synthesized from natural sources, such as silicon dioxide and other silicates. 

Rice grains also come under the natural anti-caking agent category. They are used in the other powdered ingredients to keep foods from absorbing moisture and clumping.

Does brown sugar contain anti-caking agents?

No, brown sugar does not contain anti-caking agents. Brown sugar has a lumpy texture, molasses content, and high humidity levels which do not require the addition of anti-caking agents. 

On the other hand, powdered sugar like confectioners sugar must be added with some anti-caking agents for better functioning since they are fine dry particles with a higher risk of being exposed to moisture. Usually, cornstarch or tricalcium phosphate is added to the powdered sugar.

Are anti-caking agents safe?

Yes, according to the U.S. Food and Drug Administration (FDA), anti-caking agents are a safe addition to different foods and beverages. The anti-caking agents must pass a rigorous evaluation and safety inspection on the ingredient before they are deemed safe for use. 

No anti-caking agents can be used in any ingredient unless they are specifically approved by the regulations, so you can rest assured that anti-caking agents are safe for consumption. 

Ingredients like table salt, onion powder, and garlic powder may contain anti-caking agents, but not in amounts greater than 2%, either alone or in combination as permitted by the FDA.
