Infobox references

Calcium aluminosilicate is an aluminosilicate compound containing calcium cations, most commonly with the chemical formula CaAl2Si2O8.[1] In minerals, as a feldspar, it can be found as anorthite, an end-member of the plagioclase series.

Uses

As a food additive, it is sometimes designated E556. The FDA recognizes it as an anti-caking agent for table salt when used at levels below 2% by weight, and as an ingredient in vanilla powder.[1]
