Het caseinaatphosphaatcomplex van melk
1961
Schipper, C.J.
The properties of the complex of calcium phosphate and caseinate were studied by both analytical and synthetic methods. The first approach, based on a great number of analyses of milk from individual cows, demonstrated that the composition of the complex (ratio of the various components) was widely variable, and that also Mg, Na, K and citrate were part of it. Also the cationbinding capacity of casein was studied and found to depend on several factors. By simultaneous titration at constant pH of calcium hydroxide and phosphoric acid, a complex phosphate was precipitated (relation Ca/P about 1.4), which is neither an orthophosphate, nor a hydroxy-apatite. If this titration was in caseinate solutions, a 'complex' could be synthetized. Its properties were in most respects according to those of the complex of milk. Although no definite answer could be given to the problem of the kind of bond between caseinate and phosphate, some existing hypotheses could be ruled out. The complex phosphate has distinct ion-exchange properties.
