Abstract

The preservative and nutritional qualities of calcium orthophosphate (TCP) has been previously reported. However, its protective use in processed foods and flour is mainly based on the purity of the salt. Most of the commercial salts screened were found to contain dicalcium orthophosphate as an impurity which is beneficial to insect breeding. A new quantitative method has been described for the estimation of TCP content in a binary phosphate system. The method is based on monitoring the solid phase decomposition of two salts under a controlled thermal environment. A unique technique of measuring the intermediary decomposition phase and estimating the adulterant in TCP is described and the thermal reactions are discussed
