No results found.Calcium silicate (INS 552) is a hydrous or anhydrous silicate with varying proportions of calcium as calcium oxide, and silicon as silicon dioxide. It is prepared by various reactions between siliceous material (e.g. diatomaceous earth) and natural calcium compounds (e.g. lime with varying proportions of other elements, such as magnesium, etc.). It is used as an anticaking agent and a filter aid. Specifications for calcium silicate were prepared at the 17th JECFA (1973) and an ADI “not specified ” for silicon dioxide and certain silicates including calcium silicate was established at the 29th JECFA (1985). Metals and arsenic specifications were revised at the 57th JECFA (2001). At the 76th JECFA (2012), the Committee, while reviewing the specifications for food additives containing aluminium and/or silicon, considered it relevant to update the test methods for the determination of aluminium oxide and silicon dioxide. The Committee also noted that the specifications of some additives, in cluding calcium silicate, were rather old and that additional information would be required to revise the specifications. -
