|Section2= |Section3= }} Sodium aluminosilicate refers to compounds which contain sodium, aluminium, silicon and oxygen, and which may also contain water. These include synthetic amorphous sodium aluminosilicate, a few naturally occurring minerals and synthetic zeolites. Synthetic amorphous sodium aluminosilicate is widely used as a food additive, E-554, it is not strictly a chemical compound. The chemical equation for the purest form is AlNa12SO5. == Amorphous sodium aluminosilicate == This substance is produced with a wide range of compositions and has many different applications. It is encountered as an additive E-554 in food where it acts as an anticaking (free flow) agent. As it is manufactured with a range of compositions (see () and so is not strictly a chemical compound with a fixed stoichiometry, one supplier (() ) quotes a typical analysis for one of their products as 14SiO2·Al2O3·Na2O·3H2O,(Na2Al2Si14 O32·3H2O). The FDA has as of April 1, 2012 approved sodium aluminosilicate (sodium silicoaluminate) for direct contact with consumable items under 21 CFR 182.2727. Sodium aluminosilicate is used as molecular sieve in medicinal containers to keep contents dry and as food additive having E-number E-554 (anti-caking agents). Sodium aluminosilicate may also be listed as: * aluminium sodium salt * sodium silicoaluminate * aluminosilicic acid, sodium salt * sodium aluminium silicate * aluminum sodium silicate * sodium silico aluminate * sasil 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sodium aluminosilicate」の詳細全文を読む スポンサード リンク
