Description Calcium orthophosphate (TCP) is known to be a nutritional additive
in processed foods and wheat flour. Only pure salt is highly toxic to
stored product insects. However, commercial salts were found to contain
other monobasic and dibasic calcium phosphates and carbonates of
calcium and magnesium which reduce insecticidal potency and affect
food quality. The conventional methods of analysis of these salts are
not only cumbersome but are not distinguished from each other clearly.
A new method of identification of pure tricalcium phosphate and other
associated Impurities by thermogravimetry and derivative thermogravimetry
has been described and the parameters for the identification of
the nutritional protectant salt have been characterized.
