Hancock, N. H. and McKinnon, I. and Maxwell, A. D. (2006) Universal acidity - conductivity relations in commercial bulk starter production. Australian Journal of Dairy Technology, 61 (2). pp. 189-192. ISSN 0004-9433
Abstract
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.
