Magnesium trisilicate is an inorganic compound that is used as a food additive. The additive is frequently used by fast food chains to absorb fatty acids and extract impurities formed while frying edible oils.[1] It has good acid neutralizing properties, but the reaction appears too slow to serve as an effective non-prescription antacid.[2]

Health effects

On March 12, 2007, Chinese health authorities halted the use of magnesium trisilicate at Shaanxi Province KFC franchises, suspecting it to be a possible carcinogen.[3] As a response, China's Ministry of Health conducted tests at six outlets of KFC.[4] The results showed chemicals in the cooking process at KFC restaurants in the country were not harmful.[5] 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.[6]
