Precipitant and amorphous silicon dioxide is most commonly used as an anti-caking agent.

In the process of manufacturing, storing, delivering or even final usage there’re often some factors which will lead to coagulation, caking, crosslinking, blocking or bad liquidity in powdered and granulated materials. Therefore, food manufacturers usually apply caking inhibitors (or flow agents) to address these problems.  


The amount of doses and stirring speed is very important while applying silicon dioxide as caking inhibitor. Usually, the dose is between 0.2% and 2% of the product. (The FDA regulates the maximum amount of silicon dioxide as 2%). The Stirring speed must be moderate. High stirring speed would cause runaway of silicon dioxide while low stirring speed would cause bad distribution. In order to have better contact and adherence with the host particles, silicon dioxide should be added gradually for several times in the drying procedure.
