The Chemical Composition of the Crystalline Deposit in Evaporated Milk

Abstract
Four groups of salt crystals that had separated from evaporated milk during storage were analyzed for CaO, MgO, phosphorus pentoxide and citric acid. One group of crystals was high enough in phosphorus pentoxide to indicate the presence of almost 10% tricalcium phosphate. Most of the crystals contained about 98% Ca citrate and small but varying amts. of tricalcium and trimagnesium phosphates.
