Results from the application of novel high-precision conductivity measurement to the preparation of bulk starter indicates that there exists: a universal relationship between change in conductivity and change in pH; and a universal and close-to-linear relationship between change in conductivity and titratable acidity. These results are supported by a simple numerical model of the Ca2+, PO4 3-, HPO4 2- and H2PO4- equilibria for standardised milks up to the point of complete solubilisation of the colloidal calcium phosphate.
