This method can be applied to the quantitative determination of insoluble anti-caking agents present in powdered sugars either individually or in possible combinations as approved by Codex Alimentarius [2]. In particular, the agents identified as permissible additives and which may be used in combination include calcium phosphate, magnesium trisilicate, magnesium carbonate, silicon dioxide, sodium aluminosilicate and calcium aluminosilicate. Alternatively starch may be used singly as an ingredient with anti-caking properties.
The method is essentially that described by Reichel [3]
