Magnesium trisilicate is an inorganic compound that is used as a food additive. The additive is often employed by fast food chains to absorb fatty acids and remove impurities that form in edible oils during the frying process.

Health effects[edit]

On March 12, 2007, Chinese health authorities seized and halted the use of magnesium trisilicate at Shaanxi Province KFC franchises, suspecting it to be a possible carcinogen.[1] As a response, China's Ministry of Health conducted tests at six outlets of KFC.[2] The results showed chemicals in the cooking process at KFC restaurants in the country were not harmful.[3] The Ministry of Health said tests showed that using the product to filter cooking oil had no apparent impact on health. Food scares regularly sweep the Chinese media.[4]
